CJ REAR SPRING AND SHACK SET

The CJ Rear Spring and Shack Set from Energy Suspension is engineered for Jeep CJ platform owners who demand a measurable upgrade in suspension geometry and chassis control. If you've noticed excessive play in your rear leaf spring mounts or felt the characteristic wandering that comes with factory rubber bushings breaking down, this polyurethane bushing kit addresses the root cause. The shackle assembly is critical—it controls the angle of the leaf springs under load, and worn factory bushings allow movement that degrades handling and accelerates wear on other suspension components.

Energy Suspension's polyurethane compound offers a significant durability advantage over stock rubber, resisting ozone degradation and maintaining stiffness across temperature extremes that cause factory bushings to soften and crack. The material is engineered to eliminate the compliance that allows the spring eye and shackle pin to migrate under cornering and braking loads, which directly translates to tighter steering feel and more predictable axle articulation during off-road use. This rear spring and shack set maintains proper pinion angle throughout the suspension travel range, a detail that prevents driveline vibration and binding that many CJ owners incorrectly attribute to other drivetrain issues.

Mechanics and weekend four-wheelers alike benefit from this upgrade on CJ-2A through CJ-5 models, particularly those running increased tire sizes or tackling rock crawls where axle articulation demands precision bushing performance. Installation requires basic hand tools and minimal suspension disassembly—the compact 5.8 x 2.85 x 6.7 inch package contains all hardware needed for a complete rear spring and shackle retrofit. Whether you're restoring a vintage CJ or modifying an existing platform, this kit eliminates a common source of vagueness in the drivetrain and restores the crisp response that modern suspension geometry should deliver.
