Can it be used as or with traction bars? Are there any negative side effects with a rear sway bar?

 

I can't think of any problems using both. The sway bar alone is not going to help with straight line traction though so it cannot be used as traction bars. It will help the rear stay planted in corners though.

 

with the amount of understeer these heavy pigs have, even if lowered, a rear sway bar is only gonna help matters. I highly doubt one could even stiffen the rear up enough on these trucks to induce oversteer without judicious application of the throttle.

 

traction bars usually bolt to the springs and frame in front of the rear axle, a sway bar bolts to the axle and the frame behind the rear axle so they should work together with no problems

 

You can do it I have Hotchkis Performance Front And Rear Sway Bars #2231 and a set of Calvert CalTrac Bars #3400. no problems
