JKS Manufacturing JKS1140 Adjustable Front Bump Stop for 2018–2021 Jeep Wrangler JL, 2–6-Inch Lift

JKS Manufacturing 18-21 Jeep Wrangler JL Adjustable Front Bump Stop 2-6in Lift

The JKS Manufacturing JKS1140 Adjustable Front Bump Stop is designed for 2018–2021 Jeep Wrangler JL models equipped with a 2- to 6-inch suspension lift. It helps control front suspension travel by providing a properly positioned stopping point, supporting improved clearance and reducing the risk of excessive compression during demanding off-road use. This application-specific design is well suited for lifted Wrangler builds that require dependable bump stop adjustment.
Built for suspension systems with increased ride height, the JKS1140 allows the bump stop position to be matched to the vehicle’s lift and suspension setup. Correct bump stop placement helps protect suspension components, maintain tire and wheel clearance, and promote more predictable performance when navigating uneven terrain. Its adjustable design makes it a practical solution for fine-tuning front suspension travel without relying on a one-size-fits-all configuration.
The JKS Manufacturing JKS1140 is intended for automotive applications and is sold as a single front adjustable bump stop. Verify your Jeep’s model year, JL platform, lift height, and suspension configuration before ordering to ensure proper fitment. Professional installation is recommended, particularly when installing or modifying suspension components. This product carries a California Proposition 65 warning.
