RJ-204002-1 - ANTIROCK SWAY BAR (50 IN. LONG X .850 IN. DIA.)


RockJock’s Antirock Sway Bar Torsion Bars are available in various lengths and diameters to accommodate bolt-on and custom vehicle builds and various applications from crawler to overlander. We offer a variety of bars with different center diameters, allowing bars to be swapped into vehicles as vehicle builds evolve to increase or decrease the effective rate of the bar (the greater the diameter, the stiffer the bar, granted the bar length is the same).
For ultimate strength and durability, Antirock bars are forged and heat treated 4340 chromoly, just like you would find in professional off-road competition sway bars.
This specific bar is 50 in. long from tip to tip, standard 1 in. OD at the ends with 25 splines and .850 in. diameter in the center.
