KSP Front Shock Extenders for 8 Lug Heavy Duty Trucks, 1"-3" Shock Extension Kit for 2011-2023 Chevy Silverado 2500HD 3500HD 2011-2023 GMC Sierra 2500HD 3500HD, Shock Extension Brackets Mount

Lifted the truck quite a bit and turned out amazing. Great quality and will be buying again for future projects.

Amazing fit

Have them on my 2001 Suburban 1500 and haven’t had any issues with them. The installation was easy with a torsion bar key tool. Would 100% get it again.

Works perfectly , came with all components required

These keys are just like the stock ones and prob better .. the only complaint I have is the fit was pretty loose and I did not like the loos fit with all that slop in the hex. But they did work great and that was the only complaint I have.

They was well packaged and arrived on time. They are torsion keys Not much to ssy.

I have an '02 GMC Yukon XL with an 8.1L Vortec. I was able to install these in about an hour and a half. Made a few adjustments and was able to level my rig. Kept it about stock height and am very happy with the results. Ty guys

I changed out my old keys, and put the bolts back at the same depth. My truck lost a TON of height. Even cranked all the way, it’s still not as high as it used to be. Noticed the torsion bar is stripped inside the key. They don’t fit snug and have a lot of play before it starts to crank the key. I’m confident that’s why the truck won’t raise as high as it used to. Put back my old keys and got my height back. But they are rusty and that’s why I bought new ones. Manufacture defect or something? Waste of money for me tho. BEWARE!
