- When it comes to drag racing chassis and motorsports in particular, there is a constant battle between saving weight and making a part strong enough for its job.
Year’s ago, Tim McAmis Performance Parts introduced a 4-link bracket with provisions for 4140 steel Adjustable Shock Mounts. The industry has recently seen an influx of imitation components made of aluminum.
In this video, Tim goes over the specifics of Adjustable Shock Mounts, why they are beneficial, how they are used and many of the different features and options involved.

Lowering prices while investing in your business, that’s amazing sir.
The best part is when you said “cut the cost while still providing a quality part” that almost seems like voodoo these days.
Simply amazing, How can that be? 😁
I’m not a real drag racer by any means but I find your channel awesome. I like hearing you talk about technology and parts and always give you a like. Keep it up man. 👍🏻
Glad to see you back posting....made my night!
Carroll Smith wrote in one or more of his books that while aluminium has superior tensile strength pound for pound, where stiffness is needed an aluminium part will weigh the same as a steel part if it has the same stiffness.
Tim you guys are the best! Wished I could be a hang around in your shop.
Zero deflection. The chassis now is able to ''talk" to the shock. No communication lost. Thank you
Shocks are very important. We had our shocks tuned and picked up .05 in the 60'. That was 91-92.
Great video/point. I must say, aluminum double shear mounts you see commonly these days have always made me a little nervous. And I believe they are typically 6061 and not 7075; regardless, aluminum can get pretty brittle and shock mounts certainly are stressed not only with a lot of force, but with quickly alternating forces, sometimes with high frequency; think about tire shake and/or radial setups that start the run holding the car's rear weight, then suddenly have the shock pulling against them to control extension (rebound) during the run. If a car goes up on the rear wheels/tires and the driver lets off of the throttle, nearly the entire weight of the car plus dynamic forces are suddenly on the rear shock mounts. I haven't personally seem any aluminum ones fail, but the deflection which could potentially affect the tuning is definitely something else to consider, as you pointed out. Thanks for the video, and nice product!
Very nice piece and informative video as always.Thanks.
Tim , awsome adjustable shock mount top quality
Very nice!!
Great video Tim! Thanks for sharing. It is good to see how the real pros do it.
Top notch 👍
nice stuff
Totally dig the detail, I'm into Fusion 360, manual machining & 3 axis CNC at Tinkermill in Longmont CO. Any additional would be welcome and cheered on.
,,, they look so good, think I need the 3-X size for book-ends ,,, !
Hey Tim, love your informative videos, do you have any ground-level apprenticeship openings for a shop floor sweeper for a semi-retired car guy doing his own thing on a 2000 Pro Street Camaro?
How wide is it back at the back where it mounts at to the reared thank u
19👍's up Tim McAmis thank you for sharing 🌞
Great video from the master! Wondering - if it is possible to use titanium on these components? Or is cost, or machining prohibitive? Not an expert, but thought I would ask.
Possibly...
Weight is a sign of reliability in most cases.
Tim, what are your thoughts on TI 5/8 studs?
Depends on application, horsepower, weight, etc. For the most part, we do not use them.
Although not a popular material outside of Aerospace, 17-4 Ph stainless is worth looking at. Far better corrosion resistance than steel, a simple single stage heat treat will substantially increase mechanical properties. An added bonus is the color that is created during the HT, a gorgeous dark bronze if HT'd at 900 degrees (H900). I actually prefer machining it in the H900-1025 condition then doing a short heat up to 875-900 to get the color.
Those mounts would be over the top in 17-4. Get a piece and experiment. No point in sinking more time in the shock mounts but for something else
We've used 17-4 and done the H900 HT on it before. Definitely a cool material with some unique benefits.
You guys and Motion Raceworks are some of the very few that try to keep everything made in America. You should check out their TBM brakes. 100% made in America and the only zero drag brake on the market.
You should look at carbon brakes, far superior to anything TBM makes..
Are they no drag, like the TBM brakes? If not, then they aren't superior. TBM brakes DO NOT drag any after you let off the pedal. The carbon brakes might stop a heavy car quicker, but there are other considerations when you want that last 100th of a second. @@cliffbeckwith4019
Well the other people are not rookies as well and they believe the aluminium works 🤷🏻♂️ my motto is if it works it works
Window = yummy
Running Mercer's adj on your 4130 rear mounts.
2465 w/ my ass in it, your mounts flat work...
And don’t buy any parts made in 🇨🇳……
1-2mm doesnt affect the car okay...stop talking rubbish. Car chassis will never be within 1 or 2 mm nor will a four link set up.
