I looked at leveling the truck with the torsion bar,while under there noticed that the lower a-arm aready sits on the yellow bump stop?Is this right, the truck is a 05 and only has 4000 miles on it.It has had no front end work done.....:confused:

All of them are that way. Dunno why.

GM says that they are like that to make the front springs "progressive rate".

They are suppose to sit on the a-arm. They are what make your truck ride nice. They are made of some new progessive rumber, they kinda act like a progessive rate spring. If you crank your t-bars and make a spacer to move the yellow bumpers down so they sit back on the a-arms of your truck. It will be level and still ride nice. The guys that complain about the rough ride after cranking there bars didn't move them down. My bars are cranked and I bought new yellow bumpers and made a spacer and extended the stud and now my truck rides great again. Make sure you remember to extend the guide pin on the back also. Hope this helps.

Iam glad yall know what the yellow things are.I was looking at a web site that offers a complete kit to level the truck.It comes with the green keys and four Blisten stocks at all corner for 419.00.Does this sound high?The web site is offroadunlimited.com

You probably don't need the green keys, crank up on the stockers.

i took my bump stops out and i thought the ride got a ton better. i never touched my bars either, make look a little low in the front but thats okay. rides so much better!
