I run 235/75/15 tires on stock rims with the 3" UPYOURKIA.
I broke both rear monroe shocks the first week of adding my lift kit; during aggressive driving. 5MPH with full axle articulation. <img src="/forums/images/graemlins/scared.gif" alt="" />
I thought it was the fault of the shop for not installing the bump stops. So the shop replaced the shocks with monroes and installed the bump stops. <img src="/forums/images/graemlins/smile.gif" alt="" />
Once again; they broke that week under agressive driving. I didn't understand what was wrong. <img src="/forums/images/graemlins/scared.gif" alt="" /> I got under the wheel well and jacked the axle up as far as she would go.
Finding: accessive contact between the tire and the shock. Before the lift kit the tire would tuck into the wheelwell just above the shock.
After the kit the wheel sat lower and rubbed the upper portion of the shock till it broke.
I have run the KYB brand now for three weeks with minor rubbing, but I'm more cautious and am having less fun.
Solution: I'm buying a set of wheels with 2.5" Backspace as opposed to the stock wheels with 5.5" Backspacing.
I don't know if the 3" space is going to be enough to give me full axle articulation without rubbing, but I need to try something. All advice on this issue would help, to include wheel backspacing requirements or transverse rod adjustment. Thanks.
