I've ran my rcsb at the track once or twice and it's best is 9.47. That was bone stock. I have since removed the hitch, spare tire and sway bar, along with a muffler delete.

My latest project is swapping all the control arms, and spindles over to the aluminum ones off a Z71. That alone will knock off about 50 pounds or so off the front end. It probably won't be a world of difference but it can't hurt.

Do the Z71 parts maintain the same geometry and ride height as the iron parts? I'd be willing to do that too if it's all the same. 50# is 50#!! Especially when you're portly as I am!!

I have been wanting to do this swap since I bought my truck. I've got several aluminum spindles but could never come across any a arms. I was in the process of doing a lift kit on a aluminum suspension truck. The kit I received was for a steel suspension truck. The only difference I have found is that the ball joints are bigger on the aluminum a arms. (1.0" vs .875"). I placed both a arms side by side and they looked to have the same geometry. Every where I measured was the same. I swapped my steel parts over to lifted truck and it all went together normally and the alignment went as normal.

Maybe, maybe not. Lol. I just saw the opportunity to try it for free so I did. I will add, if anybody does this. You must use both upper and lower a arms and spindles.

any chance of getting the weight of the aluminum a-arms/spindles against the steel counterpart? with ball joints and all. I dont have a fullsize to play with anymore, but i'm sure 90% of the others would like to know. i've seen more expensive / borderline hacking trucks up to lose less weight than you claim.

There is a 12 pound difference in lower a arms, 2 pound difference inot uppers and a 9 pound difference in spindles. So 46 pound difference.

46 pounds per corner?
