Yes I've run them in the past. They're really not that great. Check out my latest video as I found what I think are the best gears you can get.
this is a must for overpowered rigs. I run these on my 12S Powered XRT - great review.
Yeah definitely some good gears! Thanks for watching and if you aren't already subscribed a sub is appreciated :-)
My V2 8s Xmaxx has yet to kill them, and it has eaten pretty much everything I put in it. It rocks a Max5 with the 800kv geared 35/37. Lots of power. I did kill one set when I vaporized the rear pinion bearing. But I just rounded the teeth, but didn't actually break them.
Yeah they're very durable. I've got some new ones I'm testing now though. I'll have a video out soon on them! Thanks for watching :)
Still running stock, but alu cups, a 950kv-58113 geared 33/25. Id say, if you fail diffgears all the time, style might be first to look over, if that aint an option ( cus most say they are flawless 😁😂) ..well then this might be a good idea. If you ask me, if id buy them?. Anwser is no.
Good video, enjoyed it a lot sir!
My differential breakages are absolutely due to my driving style. I beat on this xmax in ways that I really wouldn't any other RC I have. It is The truck I take out when I want to tear stuff up. Properly shimmed the stock gears work admirably well.
Great review!
"Stupid things" = fun
Yeah but I can get expensive pretty quickly :-)
Just wondering where you find them out. Looked and seem not be able to find them. Any help would be appreciated. Thanks.
They don't have a website but you can jump into any of the X-Maxx groups on Facebook and contact Jerrel Winter.
Hi Kenny, I know this is not the most recent spiral gears you’ve reviewed. Which were the best you’ve tried that survived longest and didn’t back out?
To be honest with you I think the stock gears properly shimmed with aluminum housings and aluminum differential covers are really your best bet. They are pretty darn durable and are cheap to replace if they break.
Thanks bro
Man. I need to get me some of these!
Yeah they're pretty sweet!
Great video, really helpful. However, I'd only ask if PR Racing has any other web presence, other than a private Facebook page. I don't have a FB account (not my kind of thing), so if FB is their only means of being contacted, they might wish to consider making their page public, instead of private.
Thanks again, for the helpful video, cheers!
As far as I know they don't but I'm not affiliated with them in any way so I'm not 100% certain of that. That was just the method that they gave to contact them when I asked if they wanted me to include contact information and I told them I was making the video. I agree that it would be good for them to have an actual website though. Thanks for watching!
My kept blowing the tires off went to proline badlands with a max 6 and a castle motor things a riot
Yeah the stock tires aren't the most durable things in the world.
These gears are awesome! I have them in 2 of mine of max5 and 1100kv.
Yeah I'm a little annoyed I push them too far and broke them but I wanted to see what they could handle. They can handle quite a bit!
@@DoRC where’s that link to buy them? I didn’t see it in the description.
PR racing doesn't have a website for them. I put a link in the description to the PR racing Facebook group and you can get them through there.
@@DoRC cool. Thanks. I requested to join so I can get some pricing.
@@jerrettporter544 awesome. It would be more convenient if they had a website but as far as I know they don't. I'm not affiliated with them so not entirely sure though
Yeah helical gears can really take up some abuse, but will only be realized after a while not in one day I mean
Agreed. These were not tested over just a single pack or even a single day though. I always test things for at least a little while before passing judgment on them. Thanks for watching if you enjoy the videos they sub is appreciated!
It seems they should to be improved for strength. Maybe a different material can be used. Stock gears are only $40 a set and they break to. You broke these in one set of batteries I’m assuming in the video.
No I ran them for a few sets finally broke them doing something really stupid. Accelerating at full speed backwards and then immediately transferring to full speed forwards is about as hard as you can be on a gear. I was trying see how far they could go.
I've tried pretty much every gear option there is for these trucks and in my opinion these are the best. They're not indestructible but when you're putting those kinds of forces on a gear that can only be so large with a truck that is as heavy as mine something's going to give.
Running them for multiple sessions changes things. Yes the sudden impact of full reverse then full forward power then the flip with free wheel acceleration and the jarring landing is brutal on the ring gears. The impact might not have damaged the gears if you think about it. The reverse could have pull the pinion out causing massive misalignment thus the damage. The teeth could have literally sheared themselves apart from the misalignment. Maybe a collar around the pinion on the other side of the thrust bearing will keep it from extracting itself. Seems super strong going fowards though. So your right most the time we aren’t bashing in reverse. Please get another set and bash it only going towards to see if they are unbreakable that way. Or use the same set with broken teeth and see if they keep on going!!!!
Are they quieter to
My XRT keeps blowing up tires and I went thru 2 stock gears in 2 days
Yeah the stock gear is definitely leave something to be desired. Thanks for watching and if you enjoy my videos a sub is appreciated!
Which you prefer This or new Vitavon v2 diff?
That's a tough one. I broke them both and whereas I think they're both stronger than stock I'm not sure which one I would say is the best. The vitavon ones would probably take the edge just because you don't have to glue them into the bearings.
Have you ever tried using the Vitavon gears? They are very similar but larger than mod 1.0
Yes:)
czcams.com/video/WYDSANblNRI/video.html
@@DoRC good to know you like these better! Maybe the mod 1 of these gears helps. I stripped one of the vitavons and will try these. Do you have a link for these?
@@M3rwin6 Unfortunately there is no link to them. You'll have to join the PR racing group on Facebook and then contact them through there.
Race cars use straight cut gears because they are stronger.
Actually race cars use straight cut gears because they don't create axial forces which allows for more simple designs in the gearboxes. Helical gears are stronger but require a more complex design.
You mentioned the vitavon gears but didn’t discuss, they are similar price tag with pr gear, have u broke them yet? Which you prefer? Thanks
I've broken multiples of every gear I put in my truck. That being said I'm really hard on them. I think that the PR gears are superior.
@@DoRC thanks man!
You're welcome :-)
Hey, it's been 10 months since the video....what's your current opinion for XRT?
This is a tough one. I've tried basically every set of upgrade gears out there and honestly I still keep going back to the stock ones. A properly shimmed set of stock gears with an aluminum differential housing and an aluminum differential cover to stiffen everything up really is a durable option. It's also a heck of a lot cheaper to replace when something does break.
@@DoRC thanks! I'm not surprised with that. I figured it's probably best to allow the easiest accessible gears to be the weaker point of drivetrain.
@s21killah Yeah that seems reasonable. Having stronger gears doesn't seem to make a lot of difference it's just that for some reason none of the manufacturers have really managed to make a gear set that seems like a massive improvement over the stock gears. If someone would just come out with gears that are identical to the stock gears but made out of stronger material they'd probably have a winner but for some reason everybody seems to want to go fancy with it.
liked the video i have tore though so many diffs with my m2c racing build xmax with a hobbywing 1100kv but my question is what is a good retaining compound to use and also they don't show theses gears anymore I found the VITAVON 1.65Mod V3 Spiral Cut F&R Diff Ring Pinion Gear Set 10/32T For XMAXX what do you think
I don't have any experience with the V3 so I can't really give my opinion on them. I will say that in my experience if you're using an aluminum differential housing and an aluminum diff cover and you have good bearings and the differential shimmed properly the stock gears Are almost as durable if not as durable as any of the aftermarket options
@@DoRC nether have i tbh I'm just getting into having an xmax but I've done a lot of upgrades to it from m2c racing I got about every upgrade they make and its got pro line bedlanders but I have a set of trenches in stand by hehe anyway I've shimmed the diff with two that I have put in it and the diff still leaves the chat lol so I'm trying to find a better option and I don't beat it as you do in your videos I like to make it hall ass lol in fields and speed runs I jump it once and a while but not very high
@christianabacan5537 did you follow my shimming video?
Are you running an aluminum housing and diff cover. Dong this stiffens the area up and helps keep the gears where they should be under load
@@DoRC I don’t have the aluminum diff housing but I got the aluminum diff cover. What do you recommend for the housing housing brand meaning
So which set work best and last the longest in your opinion? I know the traxxas ones don't handle big can motors very long at all. With that said do you think pr racing gears will outlast vitavon gears if both are shimmed properly because let's face it these gears usually break when u land from a massive jump and your on the throttle or brake to correct the truck which sometimes is inevitable. I would like to know because me personally and friends have gone thru tons of ring gears.
After having tried pretty much every option I think the PR racing ones are the best. They put up with quite a bit of nonsense before they finally failed on me. I've had other options fail pretty quickly. I think the PR racing ones are definitely worth a try
I must be doing something right because I send my XRT pretty good and I run a TP 5670(102mm) motor. I've yet to have a single diff problem. I do try pretty hard not to land on throttle though so maybe that's it.
Yeah as long as you're taking care of your gears the stock gears actually work very well. This is especially true if you shim them correctly.
I ordered a set of these, hopefully they can handle an XLX2 / 2028 1100kv combo on 8s and mod 1.5 20/35T gears. I keep destroying diffs!
They'll definitely be tougher than the stock ones just make sure you shim them properly. I have a video about it. Thanks for watching and if you enjoy my videos a sub to my channel is appreciated :-)
@@DoRC I've even destroyed Hot Racing diff gears lol so yeah I'm hoping these will hold up.
Yeah the hot racing one is really aren't that good. They've got some pretty small teeth on them and I've never had good luck with them. These will be significantly better than that.
Where did you order them?
Join the PR racing Facebook group. You can get it through there.
i want to order these gears please send me a link
You're actually the previous generation or maybe even two generations old now. If you want to order the latest ones go to eBay and just look vitavon x-maxx gears.
No links?
I don't do links for two reasons. The first one is that they're always changing and a link that's current when I make the video will be outdated a month later and I don't really want to have to constantly update them. The second one is I don't want people to think I'm profiting for many affiliate links because I don't and never will.
That being said you can join the PR racing Facebook group and contact them through there to get them.
Which one better spiral or straight gear for rc?
There are arguments to be made for both. Spiral bevel gears are inherently stronger because They have more physical tooth area then straight gears do. They also have a smoother engagement which can be beneficial. That being said they are somewhat more susceptible to issues caused by misalignment which could be a problem.
In this specific instance I think these gears are the best option for the X-Maxx although the stock gears work pretty well if they're shimmed properly. Make sure you check out my shimming video for that info
@@DoRC thanks for your explaination
You're welcome thanks for watching :-)
Spiral bevel have more contact area so they are stronger design. As for the metal they made it of who knows the carbon content
Yeah they're a stronger design but they're all so more susceptible to misalignment which could be a problem. I've got some new gears coming that I think you're going to be Even better than these. Stay tuned!
Omg spiral be all better then just straight cut
It definitely has its advantages :-)
Poor customer service.. priced way to high and shipping is too much coming from the Netherlands
What was your experience?
@@DoRC I have the diffs, 1.5 mod gears and drive cup sleeves. I haven’t installed the diffs yet because the stock ones shimmed properly last a while.. The 1.5 mod gears aren’t bad but extremely heavy and a tad pricey like the diff gears.. I prefer the WFO gears or vitavon ..then add the shipping cost from the Netherlands and it’s too pricey.. I also have the drive cup sleeves for the GpM drive cups and the fit was terrible.. so loose I had to use JB weld instead of green retaining compound to secure them onto the Gpm drive cups..but I was told by Jerrel and Paul that’s normal😀 their stuff isn’t bad but I prefer to spend my money elsewhere
@@jpjplace4355 are their sleeves designed for the GPM cups or the stock ones?
@@DoRC they have a set for the stock cups and they GPM cups which are larger than the stock drive cups
Ah gotcha. Interesting info. Thanks for sharing!
