this may sound dumb but here goes. with the 429 i have replaced my original motor with I generate all the power I want but seem to have a little to much torque keep breaking rear uv. would traction bars help stabilize rear roll and keep the leaves from spreading so much on acceleration (keep having to reweld tail pipes from cutting) but still keep the power running through slop. 78 f250 custom 3/4 ton. Also is there a air locker kit similar to the setup my buddy has on his rubicon. how much$$$$
