Leafs are mounted at what angle when setting loaded? Front eye measurement and rear eye measurement?

Put ya about 11" arch in the lt. and about 10" in the rt along with removing the bottom rt leaf and grease em up real good in between the leafs and tape em so no dirt can get in them after that with duct tape . Bad fast ! Almost forgot , make sure you got a adj. lowering block to play with your rear steer and that can fix your push in a hurry .

We disconnected the rear slider, just took the bolt out and greased up the eye real good. This help give us alot more body roll, the spring was not holding the left rear of the chassis down. It worked for me , it may or may not work for you. I've worked alot with multi-leafs if you need some more help you can email me at I'm no chassis wizard but might keep you from making some of the same mistakes I already have.

Trash the multi leaf on the RR and mount a mono leaf and #150 coil spring. Take the LR multi apart, move the stack forward 2"'s, toss the bottom leaf. Tack weld the pearches to the housing on LR and toss the 5th arm.
