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 inch wide x 1 1/8 inch O.D. x 28 spline sway bar is a direct replacement for 50 inch 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.

Body Roll
- Being that this torsion bar is a considerably heavier rate that what you may have in your vehicle now, if this bar is used in unloaded vehicles, you may find this bar to be stiffer than you would prefer. This bar is intended for use on vehicles that are loaded down with a rack, roof top tent, camping gear, etc., as well as aggressive racing applications. If this does not sound like your application, you may be more of a customer for one of our standard RJ-204002-1 or CE-9900JR4-BAR bars. Front Bar
- If you are looking to upgrade both front and rear sway bars to a heavier rate torsion bar, see RJ-204002-3, our 1 in. diameter replacement for 36 in. torsion bars.
