Wilwood Pro 2.5-inch drop spindles for 1971-1987 Chevrolet C10 and GMC C15 2WD pickups using Wilwood disc-brake kits. Each cast-steel spindle has its steering arm built in.
 
They lower the front without changing steering geometry. The bearing snouts support Wilwood kit-specific hubs in 5x4.75, 5x5, or 6x5.5 wheel patterns, giving the brake conversion room to match the wheels. The 1971-1972 trucks use larger 1973-1987 ball joints and tie-rod ends with this setup.
 
Specs: Cast steel, black E-coat, 2.5-inch drop. Left and right spindles with integrated steering arms included. Part 831-15932.
