Ride Height Adjuster 8100 Series Shocks

The Ride Height Adjuster 8100 Series Shocks coil-over adjuster nut is an essential tuning component for serious automotive enthusiasts and professional mechanics who demand precision ride height control on track-built or street-performance vehicles. Manufactured by Penske Racing Shocks, a brand trusted across motorsports and high-performance applications, this adjuster nut enables repeatable, fine-tuned suspension geometry adjustments without replacing entire shock assemblies. Whether you're chasing optimal corner weights, adjusting anti-squat characteristics, or fine-tuning front-to-rear balance for road course or autocross competition, this component delivers the control professional-grade suspension setup requires.

This aluminum adjuster nut is specifically engineered for 2.5-inch inner diameter coil-over springs and features black anodized finish for corrosion resistance and durability in demanding environments. The 3 × 1 × 3-inch compact design threads directly onto Penske coil-over shock bodies, allowing instant ride height modification by adjusting spring preload without disconnecting or removing the shock unit itself. The lightweight 0.23-pound construction minimizes unsprung weight while maintaining the structural integrity required for repeated adjustments across multiple setup iterations, making it ideal for race cars, drift builds, or performance street applications where frequent tuning is necessary.

Mechanics and builders working with Penske coil-over shock kits will find this adjuster nut indispensable for vehicle setup optimization, especially when matching suspension heights to chassis geometry or accommodating tire size changes. Installation is straightforward—simply thread onto the shock body until desired preload is achieved—making it suitable for both shop use and trackside adjustments. Each unit ships individually, allowing customers to upgrade single shocks or complete suspension systems incrementally. This component is essential for anyone running Penske Racing Shocks who requires repeatable, tool-free ride height adjustment during testing, competition, or ongoing vehicle development.
