Product Description

The Wilwood 831-14201 ProSpindle front drop kit is engineered specifically for classic GM 2WD trucks, including Chevrolet C10 and GMC C15 pickups and Suburbans from the 1960s. These precision-forged aluminum spindles lower the front of the vehicle by 2.50", delivering a more aggressive stance while maintaining proper steering geometry and handling balance. Each spindle includes an integrated modular bearing hub assembly supporting both 5x4.75" and 5x5.00" wheel bolt patterns, making them versatile for various wheel choices.

Designed to work with Wilwood disc brake kits (sold separately), the 831-14201 provides a strong, zero-flex platform for radial caliper brackets, helping maximize braking performance in street, custom, and performance builds. The included left-hand and right-hand steering arms and hubs simplify installation, while the durable black e-coat finish protects against corrosion. Note that early model trucks (1963-1970) may require updated (1973-1987) upper and lower ball joints for proper fit.
