Koni 7034050000 Polyurethane Bump Stop for 12mm Rod Diameter

The Koni 7034050000 is a precision-engineered cellular polyurethane bump stop designed specifically for shock absorbers with 12mm rod diameters. This high-quality suspension component protects your shock absorbers and vehicle from damage caused by suspension bottoming.

Key Features:

• Constructed from durable cellular polyurethane material for superior longevity
• Progressive resistance design that increases cushioning as compression increases
• Prevents metal-to-metal contact that can damage internal shock valving
• Fits 12mm diameter shock rods, commonly found on Koni Sport and other performance shock absorbers
• Acts as a secondary progressive spring for controlled suspension travel limiting
• Oil, heat, and road salt resistant for extended service life

Koni bump stops function like progressive springs, offering soft initial contact that firms up as they compress further. This progressive characteristic provides safe, controlled bottoming while maintaining ride quality and preventing costly internal shock damage. Essential for lowered vehicles, performance applications, and replacing worn original equipment bump stops.
