RockJock Anti-Rock Heavy Rear Sway Bar Kit

Overlanders and Racers! RockJock heard you and the wait is over! Their heavy bar Antirock Sway Bar Kit for the rear of all Jeep JK Wrangler models features a 1 1/8 in. diameter, 28 spline bar! This heavier bar considerably increases the rate of the rear sway bar for those with racks, roof top tents, camping gear, etc. This heavy bar kit is also applicable to desert racing applications.

This kit easily bolts on with hand tools and is designed to directly replace the vehicle’s stock rear sway bar. The sway bar is made of 4130 heat treated chromoly for ultimate strength, which is the same quality used in professional off-road competition sway bars. The Antirock rear sway bar, when used in conjunction with a front Antirock sway bar, provides a more stable feeling cabin and balanced performance of front and rear suspension in rugged off-road conditions. Antirocks gives the driver increased traction by balancing and distributing the weight and traction over all four tires.

Kit Includes:

1 1/8 in. diameter 4130 heat treated chromoly sway bar

Fabricated steel frame brackets

Forged chromoly sway bar arms

Adjustable sway bar links

Stainless braided extended brake line kit

All required hardware & step-by-step instructions

Notes:

Body Roll - Being that this kit features our heavy torsion bar, if this kit is used in unloaded vehicles, you may find the rear sway bar to be stiffer than you would prefer. This kit is intended for use on vehicles that are loaded down with a rack, roof top tent, camping gear, etc.

End Links - Out of the box, the length of the sway bar’s vertical links that are included in this kit are intended for use with our suspension systems (4 in. lift). Additionally, all the link rods may also be trimmed in length for fine tuning purposes.

Wheel & Tire Clearance - If stock JK wheels are being retained, a 1.5 in. wheel spacer is required for proper tire clearance of the Antirock sway bar end links. Aftermarket wheels should have a minimum of a 4.5 in. back spacing for proper tire clearance of the Antirock sway bar end links.
