One of the problems common to serious running first gen pullers is front axle wrap. I have been fighting it for some time as have others in the sport. If you haven't experienced it, the first shock is violent, it will turn you as white as a sheet in a heartbeat. What most pullers don't know about the destructive nature of axle wrap is that the tremendous torque it takes to make the axle wrap is stolen from the engines output and never makes it to the ground. This takes a little bit out of the trucks momentum, especially if you let off the loud pedal to calm things, and it shortens the pass laid down on the track.
The source of axle wrap is really the front leaf springs, which dodge totally fwaked up day one. They arent good enough for most stock trucks. GM and Ford did a much better job on thier front leaf 4x4 trucks of the era. Most pullers have to run a 2 to 4" lift spring for tire clearance which really just pours salt in the wound. Every front spring I have seen to date has been based on dodges original design (which sucks) and they cannot be modded enough to fully address spring wrap at the power levels the chassis is now experiencing. I have added a 73-87 chevrolet 4x4 front sway bar to the front suspension on my truck to limit the severity of the spring wrap on my modded 4'' skyjacker gasser leaf pack. The bar is indirectly doing a job it was never intended to do but has temporarily fixed my problem.
I've spent the last week or so working on a new anti-wrap front leaf pack that will hopefully eliminate most or all wrap on rediculous running trucks. It has been very frustrating to say the least. I am trying to address the use of a 33x12.5 wide tire, curb height with 2000# of iron hanging off of the nose (trying not to trim the front fenders), and as much modern supension tech I can put into these springs. I will put them in The Red Eye Ram for next season and hope to seriously advance the first gens. I anticipate some other supporting mods to go along with the springs. If they work, I am considering the design of a street puller version of the spring.
