hell...i broke 3,clutches,stock 10bolt,drive shaft,tq-arm,bent 1-lca and bent both rear shocks,they almost looked like a letter L. i've been using the aluminum shaft from summit racing,its been holding alot of 6,000rpm launches w/tires off the ground. my 12bolt has 13/50 u-joints,don't know if that is also helping.
