Wilwood Iron ProSpindles (2in Drop) | 1988-2000 Chevy/GMC C1500

Genuine Wilwood Iron ProSpindles (2" drop, PN 831-15933) for 1988-2000 Chevy/GMC C1500 trucks and SUVs. These are the factory-engineered foundation for Wilwood's D52 caliper front brake upgrades and our 14"/16" big brake kit lineup, dropping ride height 2" while providing purpose-built mounting for Wilwood's caliper brackets.

Important: these spindles do NOT come with spindle nuts, and the stock C1500 nuts/washers will not work with them. You'll need our separate Wilwood Iron ProSpindle Hardware Kit (castle nuts, washers, and cotter pins) to complete the install.

Choose Wilwood ProSpindles when you want a factory-engineered, purpose-built spindle backed by Wilwood's own part numbering and design tolerances, ready to bolt directly to our D52 caliper upgrade kit or any of our 14" and 16" big brake kits built around this spindle.
