Prothane 19-1311 Bump Stop 4-1/2 in. Multi-Mount Polyurethane

The Prothane 19-1311 is a high-performance polyurethane bump stop designed for multi-mount applications. Engineered as a direct replacement for worn or degraded OEM rubber bump stops, this 4-1/2 inch unit delivers superior resistance to compression set, oils, and environmental exposure — ensuring long-lasting performance and consistent suspension travel limiting.

Key Features:

• Multi-Mount Design: Versatile mounting configuration compatible with a variety of suspension setups
• Polyurethane Construction: Prothane's proprietary urethane compound outperforms OEM rubber in durability and longevity
• 4-1/2 Inch Length: Provides controlled suspension travel limiting to protect chassis and suspension components
• Resistance to Deterioration: Withstands oils, solvents, and extreme temperatures that cause rubber to crack or compress permanently
• Improved Chassis Feedback: Firmer durometer rating compared to stock rubber translates to more predictable handling at the suspension limit
• Direct OEM Replacement: Bolt-in fitment with no modifications required on applicable vehicles

Prothane bump stops are manufactured in the USA and are a trusted upgrade for off-road, performance, and daily-driven vehicles. The 19-1311 is an ideal solution for restoring or upgrading suspension bump stop performance on leaf spring-equipped applications.
