Spindle Rocket XR1 Left

The PPM Racing Products Spindle Rocket XR1 Left is a precision-engineered front spindle assembly designed for serious performance enthusiasts and professional racers who demand reliability under extreme load and cornering stress. This left-side spindle serves as a critical steering and suspension component, handling both braking forces and lateral acceleration while maintaining precise wheel alignment. Built for track applications, road racing, and high-performance street builds, the Spindle Rocket XR1 Left replaces worn or damaged OEM spindles with a unit engineered for superior geometry and durability.

This spindle assembly features high-strength steel construction that resists the torsional and vertical loads imposed during aggressive acceleration, hard braking, and high-speed cornering. The precision-machined bearing surfaces ensure smooth rotation while minimizing runout, which translates to accurate brake rotor clearance and consistent pedal feel. The Spindle Rocket XR1 Left incorporates optimized geometry to work in concert with performance suspension systems, maintaining proper kingpin inclination and scrub radius for responsive steering response and reduced bump steer.

At 9.21 lbs, this spindle is ideal for road racers, autocross competitors, and dedicated performance car builders upgrading suspension geometry or replacing damaged components. Its robust design ensures that it can withstand the demands of competitive racing environments. The Spindle Rocket XR1 Left is a reliable choice for those looking to enhance their vehicle's performance and handling characteristics.
