- DIY Four Post Lift Modification allows you to use your four post lift like a two post lift while saving over $1000 on a rolling bridge jack!
In this DIY video I fabricate a pedestal from scrap steel and utilize a $90 12T pneumatic floor jack to lift the front or rear of your car to provide access for wheel removal, brake jobs, and suspension work.
You are a genius! If I'm ever stuck in a jungle, I want you on my team!
Did something similar, I use 2 cheap 4 ton telescoping bottle jacks, I also welded 2 pockets on a cheap cross beam adaptor so I can get wider lift points when using both jacks. Cost less than $150.
Just curious, because I have seen a lot of people buying or making(which I understand making one more) one of these jacks instead of buying the big tripod jack stands for doing the same thing. I have a 4 post lift and it's so simple to use, get the car to whatever height you want and slide jack stands under it. Great video by the way, always enjoy watching fabwork.
Love the channel, great vid. Smiles all the way around putting down a GT350, Vette and Jag. Liked the twin turbo install with details and commentary. Won't be doing that on my '22 Mach 1 w/handling pkg on order as I love the twisties. Keep it up!
Thanks for watching and the kind words!!
Is this any different than the jack trays that come with many 4 post lifts from the factory? They are meant for exactly this. It's just a metal tray you place your bottle jack or whatever in. Even the cheap lift I am looking at comes with this jack tray.
The only real difference I can see is that yours allows you to use a larger bottle jack than typical. But at the end of the day the mini bottle jacks usually work well since all you really need is to raise it up enough to get the tires off the base.
So my lift cam with plastic trays but you couldn’t lift from them. I had a metal tray but the issue was my cars are low and you needed to get a low profile jack in there which could also lift it high enough to get the wheels off. So you are right its the same idea but my stock tray was the wrong height to fit my applications. Would have worked fine for a truck, suv or car with more clearance.
@@truckandroll989 That's why I was considering using a mini bottle jack. I haven't actually done this yet but am looking into it versus just buying the scissor lift attachment. My cars are about 4-5 inches from the ground so not crazy low but low enough. It's just hard to find a good mini bottle jack with a decent lift too.
The other issue with the scissor lift is they typically require about 4 inches of clearance under the car. So I am still on the fence here if that would even work for my car, sometimes parts hang a bit lower than the bumper does. It's unfortunately not a simple issue to fix unless you have a welder and metal like you did here. It would cost me a fair bit to have someone fabricate the same thing I think.
@@jdmcarrepairs142check out the air bag jacks, they have high capacity both weight and lift from a very compact package.
Have you considered using an air bag jack with your flatter jack tray? I recently installed an old 12k 4-post lift and just got a 5 ton air bag jack to try and lift vehicles from the body seam sides so I don't need to be underneath. My lift came with no accessories so I may try making a jack tray or buying one so I can lift from the center if I want.
Honestly, its a really good idea. Ive seen them and they look really cool! Unfortunately I had to sell the lift and now rent that place. The new shop is a 4 car garage but no lift :/
Great Idea. I have been debating 2 vs 4 post lift purchase and a mod like this could be the deciding factor. You did not say specifically, but your main downside is that it hangs too low (how many inches?) to put the ramp all the way down for when you drive a car on? I can think of three solutions (but i am not sure they are worth the cost effort) a) less deep tray, but this probably means a shorter (and less lifting capacity) jack, b) cut out some of your garage floor (doubt it) and c) ramp extensions. longer ramps would keep your approach angle low without having to lower the lift all the way. any thoughts on these ideas?
So if the main issue is lifting height. This lift comes with a tray but any of the available jacks are either not low profile enough or dont lift high enough to make it work. A hinged tray, like what i made but with hinges, could work but would be more time consuming. They sell sliding scissor jacks which solve all of these problems but cost a decent amount. Ramp extensions could work but its one more thing to build and you are driving a car up onto a partially raised lift which may technically be a “no-no” but maybe in reality NBD
@@truckandroll989 good points. I would imagine there is quite a bit of vehicle variation in lift needs to calculate as well. thanks again for the post.
A four post lift is the correct choice if you have long term storage needs. If you're planning on doing your basic maintenance, a two post lift is far more useful.
My brother has a four post lift, but he uses my two post lift for brake jobs, or when he rotates the tires on his wife's import car. With out a bridge jack, his 4 post is almost useless for many tasks. Smaller cars and some small SUVs have a narrow stance, and without a bridge jack you may not be able to get on a decent jacking point if you are relying on lifting from the ramps.
Does the car have any tendency to tip a bit once one wheel is removed? What about positioning the jack under the side you want to remove the wheel on? It looks safe enough,, but I keep imagining if the car tipped enough and the jack kicked out, and then the car slid off the lift.....
So not really shown here but id put small jack stands beneath the car once it was high enough to remove the wheels. As for sliding off the lift to a one side nah. Basically lift from center, jack stands in, lower and do whatever you want safely. Thanks for watching!!
What lift do you have? Thinking about buying one. Thanks.
Mine was made by Tuxedo. It is their extra long and extra tall model. Good for 8-9k lbs i believe. Im 6’5” so I need the extra height
