RockJock Antirock Sway Bar 50in Long x 1.125in Dia. x 28 Spline

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!
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, 1.212 in. OD at the ends with 28 splines and 1 1/8 in. diameter in the center.

Component Specs.:

• Length  =  50 in. (tip to tip)

• OD (of splines and bushing surface)  =  1.212 in.
• OD (of center of bar)  =  1 1/8 in.

• Finish  =  semi-gloss black powder coat (bushing surface and splines masked)

Notes:

• Any 28 spline arms we offer will fit this bar
• This bar will directly replace bars found in our bolt-on kits that feature a 50 in. long bar, and may be swapped into a vehicle that is already equipped with a 50 in. long bar to change the vehicle’s effective sway bar rate. However, be advised, this 50 in. bar with the larger 28 spline may only be used in conjunction with the 28 spline bar specific bushings as well as one of our 28 spline arm sway bar arm sets.
• If you are swapping this bar into a vehicle, be advised 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.
• 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.
