Hello guys i have an 05 z85 LS extended cab, and my stock leafs are toast. I just received my belltech leafs this weekend. I am wondering if need to order special u bolts for them or if i can just get the OEM ones from rock auto? I wont be using any blocks. Also if anyone happens to know where i can find a set of traction springs that would be greatly appreciated. I have been looking online for the hellwigs that 1BADI5 has but i cannot find them anywhere. Thank you for your time.
