I heard somewhere that in replacing the rear leaf bushings, it was better to go with poly in front and rubber in back or vice versa. I am running this car in the F.A.S.T. class with an auto and a real big block. Also, does anyone know the spring rate of the factory XHD leafs and or height? Thanks, Brad

Yes the front eye sould have aluminum or poly. The front of the leafs should b e bolted to the first leaf. I mean run a 9/16 bolt through the top leaf and the next leaf only at the front just behind the front eye. This sould be good in the FAST class as well. If your just straight lineing then just the front is fine but for the corrner carver you want polly in the back as well. Mopar was never realy good at giving spring rates out as good as they are at giveing part numbers out. You might be on your own there.
