Not sure which 2003 GMC Sierra Suspension Systems are right for you? We have over 6546 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:

"If you are tired of seeing hydraulic fluid on your floor or in your drive it may be time for some Bilsteins. They are easy to order from AutoAnything and install quickly; no lift needed in my case. They fit good with fastenings included." —Larry R from Windsor, ME bought a Bilstein Heavy Duty Shocks for a 2003 GMC Sierra.

"What a great kit! The directions were good, the kit was self explanatory, it all went together really smooth . I had about 3 hours into the total project." —Scott L from Kalamazoo, MI bought an Air Lift Air Bag Suspension Kit for a 2003 GMC Sierra, 2500, light-duty, factory bed.

"I wanted to replace my factory rear shocks on my 2003 GMC Sierra 2500HD. I wanted shocks that looked good but more importantly maintained the factory ride. I read the reviews on these shocks and decided to buy them. The price was right and they great. I am very happy with these shocks. Install was pretty easy. I am no mechanic but am able to perform routine maintenance in my own. Install time was perhaps longer than most but again I'm not a mechanic nor do I have any fancy equipment. Overall I am pleased with my purchase." —Steven G from Collegeville, PA bought a Skyjacker Lift Kits for a 2003 GMC Sierra.

"They lifted my truck to the perfect amount without having to use block to equal out the rear. However, for what they are, they are way too expensive. I ordered these thinking I would get shock extenders too for the price but they weren't included or needed. There are better lower price options for just keys IMO." —Raymond B from Hanover, PA bought a SuperKeys for a 2003 GMC Sierra.

"Did a fair amount of research, true to other reviews these are great shocks. Easy install, just did rear on gmc 2500HD duramax. Price was best I could find with free ship, arrived in 2 days. Haven't towed boat with them yet but I do have a 12 gal cng tank in bed. I notice no more kidney punches when driving over dips. Feels stable on freeway and holds well in snow storms. Will be putting fronts on when current ones start to go." —J.p G from Slc, UT bought a Bilstein Heavy Duty Shocks for a 2003 GMC Sierra.

Air Lift Wireless Air Compressor System

overall a very nice setup

The installation was not too difficult; although the instructions could have been better. I would have given five stars if the install instructions were better. Otherwise, it is working great. I agree with Air Lift's recommendation to use a pipe cutter to cut your tubing. View more reviews...

Air Lift WirelessOne Air Control System

Good choice

Easy install. The instructions were easy to follow. I thought I may not have enough airline to route to the existing lines on the air bags. Air lift sent me another 10 foot length for free. Ended up I was just there with what they sent in the kit. Good Price from AA. The $50 rebate was the icing on the cake for me to buy this kit. The remote works really good. I'm impressed!

Firestone In-Cab Air Command Kit

Firestone in cab air

The only things II would like to see is a switch that is included in the kit to turn it on and off and a little heavier gauge wire that powers the compressor. I realize pumping air bags it does not run a extended length of time but what if you have to air up a tire? View more reviews...
