Wilwood Pro 2.5-inch drop spindles for 1963-1970 Chevrolet C10 and GMC C15 2WD pickups, built for Wilwood disc-brake kits. The steering arms are cast into the one-piece spindles.
 
The drop brings the nose down while retaining steering geometry. Traditional bearing snouts accept Wilwood kit-specific hubs in 5x4.75, 5x5, or 6x5.5 wheel patterns; stock 1963-1970 tie-rod ends stay in use with the required larger 1973-1987 ball joints.
 
Specs: Cast steel, black E-coat, 2.5-inch drop. Left and right spindles with integrated steering arms included. Part 831-15931.
