Product details
Overlanders and Racers! If you've been in need of a heavier rear sway bar to support the added load, and resulting sway) of the addition of a rack, a roof top tent, camping gear, etc. – or – if you are a desert racer needing more control, RockJock has the solution! Their 50 in. wide x 1 1/8 in. O.D. x 28 spline sway bar is a direct replacement for 50 in. wide bars in any of our standard Antirock Sway Bar kits – regardless of application. Because of the larger diameter and spline count of the bar, the sway bar arms must also be replaced with 28 spline arms as well as the sway bar bushings being replaced with larger I.D. bushings. However, with all of the upgrade parts in hand, you simply unbolt the arms from your existing bar, slide the bar out, replace your sway bar bushings, and then install this larger bar and 28 spline sway bar arms! Sway control will be dramatically improved in loaded or racing applications. Bar is constructed of forged 4130 chromoly and finish is semi-gloss black powder coat. Antirock® Sway Bar; 50 in. Long x 1.125 in. Dia. x 28 Spline; Antirock® Sway Bar
