Shaft Nut Penske Bump Stop

The RE Suspension Shaft Nut Penske Bump Stop (MPN: RE-BR-NT73) is a vital fastening component designed for performance suspension systems, particularly those utilizing Penske coilover or bump stop assemblies. This shaft nut acts as the retention mechanism that secures bump stop cartridges and valving components to the main shock body, ensuring consistent preload and preventing unwanted component migration during aggressive driving or track use.

Engineered to withstand the radial and axial loads inherent in damper cartridge assemblies, this precision-machined nut ensures reliable thread engagement and torque retention under repeated compression cycling and thermal expansion. Its lightweight profile minimizes unsprung mass while maintaining the structural integrity necessary for bump stop stack tuning and valving adjustments on modern coilover platforms. Proper installation with an appropriate thread-locking compound is essential to guarantee performance consistency across multiple heat cycles.

Technicians and suspension builders working with RE Suspension or compatible Penske-style bump stop kits will find this component indispensable for maintaining suspension geometry and ride quality. Whether for street-performance setups or competition-grade suspension platforms, a properly secured shaft nut is fundamental to achieving optimal performance.
