Product Description

The Wilwood 831-15932 ProSpindle Kit is a front suspension upgrade engineered for 1971-1987 Chevrolet and GMC 2WD C10 and C15 series trucks, including pickups, Blazers, Suburbans, and Jimmys. Featuring a 2.50" drop, these cast steel spindles lower the front ride height for an improved stance while preserving correct steering geometry and alignment, making them an ideal choice for performance builds and custom classic truck projects.

Sold as a matched pair, each spindle includes integrated steering arms and a traditional bearing snout designed for Wilwood kit-specific hubs. The durable black e-coat finish protects against corrosion, and the drop design works seamlessly with compatible Wilwood disc brake systems featuring a variety of wheel bolt patterns. This kit is perfect for builders looking to combine lowered front suspension with high-performance braking upgrades without sacrificing handling precision.
