Shaft Nut Penske Bump Stop

The RE Suspension Shaft Nut Penske Bump Stop (MPN: RE-BR-NT73) is a precision-engineered shock mount fastener designed for Penske shock installations on performance and race vehicles. This polished steel nut secures the shock shaft to the vehicle's suspension mount point, delivering the tight, vibration-free connection critical for consistent suspension geometry and predictable handling dynamics across extended track sessions and off-road applications.

Manufactured from durable steel with a polished finish, the bump stop nut resists corrosion and maintains consistent clamping force even under shock loads from rough terrain or prolonged high-speed use. The compact dimensions (3.1 × 0.35 × 3.15 inches) and minimal weight (0.08 lbs) ensure integration without adding unsprung mass to the suspension system. As a wear item and critical fastener in shock assemblies, this nut should be inspected regularly during routine maintenance and replaced when stripped threads or corrosion appear, ensuring the shock assembly maintains proper preload and alignment.

This component is essential for users building or maintaining Penske shock-equipped suspensions on race vehicles, rock crawlers, desert runners, and high-performance street machines where reliable shock mounting is non-negotiable. Whether replacing a damaged fastener or stocking spares for extended race weekends, the RE Suspension bump stop nut ensures repeatable suspension performance and eliminates the risk of loose shock connections that compromise handling and increase component wear.

RE Suspension specializes in OEM-grade suspension components and fasteners for performance and off-road platforms. This shaft nut represents the precision-focused engineering required for systems where suspension geometry directly determines cornering grip, impact absorption, and vehicle stability.
