Unlock maximum articulation and superior off-road performance for your 2018 and up Jeep JL Wrangler or JT Gladiator with the RockJock Johnny Joint Front End Housing Kit. This essential upgrade is designed to replace the restrictive factory rubber bushings on your front differential housing's upper control arm with high-performance Johnny Joint® rod ends. By doing so, it allows for significantly increased suspension travel and flexibility, crucial for navigating challenging terrains.
The kit includes precision-engineered Johnny Joint® inserts that seamlessly integrate into your axle housing, providing a robust and durable connection point. Along with the inserts, you receive greasable bolts for easy maintenance and extended lifespan, plus a specialized installation tool and comprehensive instructions to ensure a smooth and hassle-free setup. This upgrade not only improves your Jeep's articulation but also enhances the overall strength and longevity of your front suspension components, making it a vital addition for serious off-road enthusiasts.
Upgrade your Jeep JL or JT's front suspension with the RockJock Johnny Joint Kit for unparalleled performance. Available now at GGCRACING.
