great riding shocks

easy to install, ride was great, a lot better then the rancho quick lifts were that I had on before, would be nice to buy then already loaded with springs, but no big deal.

Really good shocks

I bought these for off road when I hunt, expecting a harsh on road ride. Big surprise the on road ride is better than the stock shocks were when they were new. Off road is what I was looking for good bump absorption and great control. Truck sits slightly higher than stock which looks pretty cool.

Great! These bilsteins leveled my silverado 1500 nicely to fit 285/65/18 tires. It rides at least as good as stock, probably a bit of improvement in my opinion. Difficult to install only because you need from spring/strut assembly. Had a shop do it for a decent price in only a couple hours. Definitely recommend if you are trying to level your truck.

Great Shocks!!

I have a 2011 Chevy Silverado 1500 crew cab. These shocks raised the front end 1 3/4 inches and eliminated the nose down rake that I didn't like, without having to install a leveling kit or tamper with the OEM engineering. Also gave the front end a "stronger" feel.

These are perfect!

I have a new GMC Sierra 1500 SLE Crew Cab. Wanted it to look like a real truck so I went with Bilstein 5100's front and back. Put a 3/8" ReadyLift shim under the adjusteble front shock on it's highest setting plus a 1" ReadyLift taller block in the rear. Truck is 2 1/2" higher in front than stock & 1" higher in back. Still has a 1/4" rake for trailering without it being rear end low. Have more travel than stock with an awsome ride & look. Added 33" BFG All Terrain's. Can't be beat!

Hello, I have a 2011 Chevy Avalanche Z71 and I want to lift the truck in the front. How high can I lift it with these shocks? Do I need to lift the rear also and if so what part # shock do I need? I see these do not come with boots, where can they be purchased or are they not necessary? Thank you. John
