Amazing Upgrade From Stock With 2.5" Lift!!!!

Reviewed By Stephen H (WARWICK, RI) Reviewed for a 2004 GMC Sierra —10/28/2014 11:27 AM

I did a torsion key lift on my '04 Sierra 2500hd DMax, and it pushed the lower control arms down so much, that the front end would "BANG" on bumps. I upgraded to the Bilstein 5100's, and the ride is totally amazing!! Almost better than stock, and with the Air Lift 5000 Ultimate kit on the rear end, my 40' Fifth Wheel doesn't sag the rear end!! Definitely worth the money and 1 hour worth of time to install all 4!!! Plus, you can't beat the customer service at Auto Anything!!

The airbags & brackets are top quality and installed easily & fit perfectly. I had one small leak and was helped by customer service. Have not towed with them yet but I hooked it up to my 5th wheel and checked them out. I believe they will work perfect too. I'm happy with them.

GMC 2500 Slide in Camper

Reviewed By Eric M (Aurora, CO) Reviewed for a 2004 GMC Sierra —4/28/2011 9:33 AM

Install was easy as long as you have the right tools. Installed on GMC 2500 to beef up suspension for slide in camper and pulling boat. So far they seem like a good purchase. Really make the truck ride better with the camper on.
