Is this diesel wide or a certain places. Wondering, I wanna put my stocker in the work stock class at BUCK Motorsports and see how the beauty does. What do you mean 1" travel on rear by the way?

rules are different for every org that pulls so those rules are kinda general. for instance the 2.8 class dosnt really exist any more because there are very very few orgs that still run that class. the 1" travel means there must be 1" between the bump stops on the rear axle. this lets you build some suspension compression limiters but you dont get to run a soild rear suspension like the upper classes.

imo the 1" rule is the dumbest rule out there because all it does is let the rear suspension unload and load causing bounce and driveline breakage. the same result could have been had with simply lowering the hitch height to 25" instead of 26"

would a leveling kit affect anything?..

Not really almost every truck that pulls workstock around here is leveled with 35" tires

Sent with a Droid RAZR in one hand and 14,000 volts in the other.

well im not really worried anything will break, i just want to experience pulling before i have to spend all my money on trade school. Just want to get everything in order before i show up to the pulls looking like a dummy. Maybe even afterwards it might become a money pit kinda hobby :humm:
