We actually installed a prototype on our truck on Friday. The strut pattern is completely different and the actual strut is different. We are developing a couple other pieces as we test a 1" spacer. Have room to add more if we do a pre-load spacer.
We are limited to just a 1" spacer on top of the strut without causing the customer to re-clock the top hats and cause increased installation complexity as well as make the shock too long overall causing UCA issues.Measuring the truck I find a 1-1/2 stance difference.Shouldn’t it be a lift of 1-1/2 inch spacer design to allow for settlement and if some one puts a aftermarket bumper or winch design.Throught’s ?
I don't think you would have to do much with a 1 inch. Just alignment, adjust headlights, possibly adjust the camera in the front for advanced braking and following distance. I have not installed a lift yet, so not sure.If you install lift kit, do you need to have the safety systems recalibrated?
The guys at shock surplus are clueless on fitments lol I know first hand that none of those on the market right now fit.According to Shock Surplus via online chat this kit fits:
Eibach Pro-Truck Lift System Stage 1 Kit for 15-22 Colorado 2-3" lift (shocksurplus.com)
Fox and Bilstein were also mentioned to fit.
BUT after a phone call to Eibach this part# is not confirmed that this will fit, I am about 20min away from Eibach and I offered up my 2023 Z71 to check for filament.
The Tech on the phone did say that they had a GMC AT4 in the shop but can't confirm that it's the same suspension configuration as the Colorado
I'm the guy (Bill) you were chatting with on your website this morning.The guys at shock surplus are clueless on fitments lol I know first hand that none of those on the market right now fit.
Eibach had our AT4 in the shop for measurements. But like you said they don't have an eta. I can confirm its the same suspension as a Trailboss and can confirm its different suspension from the Z71/LT/WT - but the mounting positions should be the same but will be likely a shock length difference between the two.
