Overlanders and Racers! If you’ve been in need of a heavier front 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!

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 36 in. long from tip to tip, standard 1 in. OD at the ends with 25 splines and 1 in. diameter in the center.

Kit Fits:
  • Universal Application
  • Included in some JL Wrangler front Antirock Sway Bar Kits
  • Included in some JL Wrangler Unlimited front Antirock Sway Bar Kits
  • Included in some JK Wrangler front Antirock Sway Bar Kits
  • Included in some JK Wrangler Unlimited front Antirock Sway Bar Kits
  • Included in some JT Gladiator front Antirock Sway Bar Kits
Kit Includes:
  • (1) Sway Bar Torsion Bar (36 in. long x 1 in. x 25 spline)
Component Specs.:
  • Length  =  36 in. (tip to tip)
  • Spline Count  =  25
  • OD (of splines and bushing surface)  =  1.000 in.
  • OD (of center of bar)  =  1 in.
  • Threads (in ends of bar)  =  5/16 in.-24 x 1 1/8 in. deep
  • Finish  =  semi-gloss black powder coat (bushing surface and splines masked)
Notes:
  • Any 25 spline arms we offer will fit this bar, however this heavy rate bar is NOT for use with aluminum sway bar arms!
  • This bar will directly replace bars found in many of our bolt-on and universal kits, but may also swapped into a vehicle that is already equipped with a 36 in. long bar to change the vehicle’s effective sway bar rate.
  • 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 CE-99001B or CE-99001D bars.
  • If you are looking to upgrade both front and rear sway bars to a heavier rate torsion bar, see RJ-204001-1, our 1 1/8 in. diameter replacement for 50 in. torsion bars. Be advised: this 50 in. bar is a larger, 28 spline so it requires new sway bar arms and bushings for installation.
