Prothane 6-1302-BL Front Strut Bump Stop Kit Black

The Prothane 6-1302-BL is a front strut bump stop kit engineered from high-performance polyurethane to protect your suspension from the damage caused when it bottoms out. Unlike factory rubber bump stops that crack and deteriorate over time, Prothane's urethane construction delivers superior energy absorption and long-lasting durability.

These progressive-rate bump stops feature unique internal chambers molded directly into the urethane that create a progressive compression rate — absorbing impact gradually rather than all at once for a controlled, predictable feel. The integrated poly-lock system bonds the polyurethane element and mounting bracket into a single, rugged component.

Key Features:

• Progressive-rate polyurethane construction absorbs suspension impacts progressively to protect chassis components
• Multi-mount design allows quick and easy retrofitting to your specific application
• Poly-lock system integrates the urethane bump stop and mounting bracket into one durable unit
• Black urethane with graphite additive — same durometer as red version, with potential squeaking reduction
• Direct-fit replacement for factory rubber bump stops
• Height: 1.9 in. | Top diameter: 0.9 in. | Bottom diameter: 0.6 in.
• Sold as a 2-piece kit (one pair)
• Made in the USA
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Prothane polyurethane suspension components are a proven upgrade over OEM rubber parts, offering improved durability and consistent performance throughout the life of your vehicle.
