RockJock Antirock Sway Bar – 36" x .850" – 25 Spline
CE-99001D
The RockJock Antirock 36" Sway Bar – .850" Diameter – 25 Spline is a forged and heat-treated 4340 chromoly replacement or custom sway bar designed for RockJock Antirock suspension systems. At 36" long with a .850" center diameter, this bar provides a specific sway bar rate for crawlers, trail rigs, overlanders, Jeeps, and custom off-road suspension builds.
RockJock uses the same 25-spline configuration across compatible Antirock arms, making this bar useful both as a direct replacement and for changing the effective sway bar rate on an existing 36" Antirock system. The bar features 1.080"–1.085" spline and bushing surfaces with a semi-gloss black powder-coated finish.
Includes:
- (1) RockJock Antirock Sway Bar
Note: Sway bar arms, bushings, brackets, links, and mounting hardware are not included unless otherwise specified.

Fitment Notes
This bar directly replaces the 36" x .850" bar used in compatible RockJock Antirock systems. It can also be used to change the effective sway bar rate on vehicles already equipped with a compatible 36" Antirock setup.
RockJock 25-spline Antirock arms are compatible with this bar. Verify bar length, bushing locations, arm spline configuration, and suspension packaging before using it in a custom application.
Tech Insight
1. What does the .850" sway bar diameter affect?
Bar diameter affects the effective spring rate of the sway bar. When comparing Antirock bars of the same length and material, increasing the center diameter produces a stiffer bar, while decreasing the diameter produces a softer bar.
2. Can I use this bar to change the rate of my existing Antirock system?
Yes. If your existing Antirock system uses a compatible 36" bar and 25-spline arms, changing to a different center-diameter bar allows you to alter the effective sway bar rate without replacing the entire system.
3. What sway bar arms fit this bar?
According to RockJock, any of its 25-spline Antirock arms will fit this bar.
4. Why is 4340 chromoly used for the Antirock bar?
The bar is forged and heat-treated 4340 chromoly for the strength, durability, and torsional performance required in demanding off-road suspension applications.
5. Can this sway bar be used for a custom suspension build?
Yes. The 36" length and 25-spline ends make it suitable for universal Antirock installations when the chassis, bushings, sway bar arms, links, and suspension geometry are properly designed around its dimensions.
