Maximize Off-Road Traction with the RockJock JT Antirock Rear Sway Bar Kit

For Jeep Gladiator JT owners who demand superior off-road performance, the RockJock Antirock Sway Bar Kit is an essential upgrade. This heavy-duty rear sway bar kit features a substantial 1 1/8-inch diameter, 28-spline bar, significantly increasing the torsional rate compared to stock. This enhanced stiffness is ideal for overlanding rigs, vehicles carrying heavy gear like rooftop tents, or demanding desert racing applications, providing balanced suspension performance and improved traction across all four tires.

Engineered for Balanced Performance

The Antirock system is designed to work in conjunction with a front Antirock sway bar (sold separately) to create a balanced suspension setup. By eliminating the binding associated with traditional sway bars during articulation, the Antirock system allows for more consistent tire contact with the terrain. This translates directly to increased traction, better stability, and improved driver control, especially in rugged off-road conditions.

Durable Construction for Extreme Use

Crafted from SAE 4130 heat-treated steel, this sway bar is built for ultimate strength and durability. The kit includes forged arms and all necessary components for a direct replacement of the stock sway bar. The design ensures that it integrates seamlessly with your JT Gladiator's existing suspension, providing a noticeable improvement in handling and capability off the beaten path.

Key Features:

  • Heavy-duty 1 1/8-inch diameter, 28-spline bar for increased torsional rate.
  • Optimizes suspension balance and tire traction for off-road use.
  • Constructed from high-strength SAE 4130 heat-treated steel.
  • Direct replacement for the stock JT Gladiator rear sway bar.
  • Ideal for overlanding, rock crawling, and desert racing.
  • Works best when paired with a front Antirock sway bar kit.

Elevate your Jeep Gladiator's off-road prowess with the RockJock JT Antirock Rear Sway Bar Kit. Experience enhanced traction and balanced suspension performance on your next adventure. Find this and other performance upgrades at GGCRACING.
