I have a new pair of rear leaf springs that I got with a 85 4Runner that was never installed.I want to put them on my 88 4Runner , they are 2" lift part number N73200 (Rear Spring (pair) '84-'88 2")from NWOR. Will they require longer shocks and u-bolts?

Thanks

 

If they are the same amount of leafs as the current ones on. No. But... it is recommened that you should. When i did mine, couple of the bolts backed out from being streched the first time. Might as well replace them, cheap insurance for your axle not falling off.
