ZUK mod question for 91 pickup
 

hey guys Im new to the forum, but I have been reading the forum for years. Ive got a few questions... I have a 91 toyota pickup 4x4 22re. I recently got a set of 33x12.50 BFG KM2s for cheap. I have a set of American racing tailgunner wheels 15x8, which I believe has around 4 inches of back spacing. I have no lift yet, just ordered my BJ spacers yesterday to allow more travel in the front end. When I put the new 33x12.50s on they rubbed a little bit at full lock. I will hammer out the pinch welds this weekend. My question is... I had a 2007 fj cruiser and put the OME lift kit on it and I still have the stock coil springs from the FJ. I have a pretty saggy rear end and was wondering if anyone had ever used stock FJ cruiser springs to do a ZUK mod on a 91 pickup. The front spring from the stock FJ are about 14.5 inches and the rears are around 14 inches. Im hoping the rear springs from the FJ will fit over the bump stops so I dont have to cut anything. But because I will only have a BJ spacer in the front end, Im worried that the rear end of the pickup will be too high if I put in the FJ spring. If it is too tall, should I cut the springs down or take a middle leaf out of the rear leaf springs?

Anybody? The rear springs are a little under 14 inches and have a 5 inch ID and a 6 inch OD. The front springs are a little over 14 inches and have about 4 inch ID. The front springs were coil overs on the FJ and are really stiff. The rear springs are a lot softer than the fronts. I can't find anything on the Internet about poundage of stock FJ springs. Any ideas guys?

ive done a couple of zuk mods, one on my 92 pickup that i just removed because it was extremely stiff. i used the tj jeep springs and was dissapointed.i wouldnt use any more than a 125lb spring.check into these springs.http://api.viglink.com/api/click?for...13341679154411
