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.

Kit Fits:

  • Directly replaces the sway bar torsion bar in all of the below applications, previously equipped with an Antirock Sway Bar
  • Jeep Wrangler JL Unlimited (4-door)
  • Jeep Wrangler JL (2-door)
  • Jeep Gladiator JT
  • Jeep Wrangler JK Unlimited (4-door)
  • Jeep Wrangler JK (2-door)
  • Universal applications that use a 36 in. wide bar

Kit Includes:

  • (1) 50 in. wide x 1 1/8 in. O.D. x 28 spline sway bar torsion bar

Fitment Specs:

  • This bar will directly replace any of our existing 50 in. wide sway bars in any application (again, with the mandatory addition of the larger spline sway bar arms and larger I.D. sway bar bushings).
  • Use with any of our 28 spline sway bar arms and 1 1/8 in. I.D. (28 spline) sway bar bushings.

Component Specs:

  • Construction = forged 4130 chromoly
  • Length = 50 in.
  • O.D. = 1 1/8 in.
  • Spline Count = 28

Notes:

  • 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.

Good quality
Color: Ultra, Size: Large, Color: Ultra, Size: Large
Great quality. I purchased for my daughter’s dog who destroys all toys. This toy holds up. I didn’t realize it was a large and the chickit stick she had was a medium. The large ball ended up working out good for playing inside the house. The dog likes it a lot.

Please read!
Color: Ultra, Size: Large
This dog ball is so useful! We have a large property and we use the Chuckit! thrower with the ball. The color and material of the toy is very high-quality and lasts for a long time. We have been using the Chuckit! brand for a long time now and we love their dog products! It is a good price and we buy replacement balls like once or twice every 6 months because they keep getting lost in bushes or trees 😂 After some time the color of the ball gets washed out and since our dogs are aggressive chewers, one of the balls we got broke and split open, but it was still usable! The reason that one broke is because we had it for a HECKA LONG TIME! It has no squeaker so when your dog has the ball it wont make any loud and annoying sounds. It is easy to pick up with the thrower and it seems durable and sturdy enough to last them a few months. I don't recommend as a cat toy because this ball is specifically designed for dogs. But is your cat likes fetch i guess it could work! The ball is soft enough to not be hard as steel, but is sturdy enough to not break immediately.

Perfect size and strength for my small dog that is a heavy chewer! She hasn’t been able to destroy and chew up this one like she has with every other toy! Definitely chew resistant.
