Pinion angle

[wrivord]

Hey guys,

I need a little help with figuring out the pinion angle on my 69 Coronet. This is what has been done: weld in sub-frame connectors, front and rear torque boxes, XHD leaf springs, A833 transmission, 8.75 rearend (489) 3.55:1, Bilstein non adjustable shocks, 500" wedge (600HP/600TQ).

The only change from stock that I made was using front spring hangers from Mancini's. They are the type that have two holes, one for stock position (bottom) and one for lowering the car approx. 1 inch (top). After I got the suspension together, I realized that the pinion angle was not sitting correctly as this moved it up (toward the bottom of the car). I have shims to correct the angle, I'm just not sure what the appropriate angle would be.

Any advise on setting this up would be greatly appreciated. Thank you, Bill.

Your car sounds pretty stout, so I would recommend what the MP suspension book says. 5-7* pinion nose down in comparison to thr drive shaft. Do you have a Mopar suspension manual? I highly recommend one. Mancini's. Ten bucks. Buy one.

Here you go.

I Had The Same Problem With My '65 Plymouth Regarding The Pinion Angle. Super Stock Springs Came From Mancini Also. Rob Is Right When He Said 5-7 Degrees Pinion Downnose. Mine Came In At 7!
