Title: Spindle comparison: HD vs Std and lower vs Stock
Post by: Captkaos on March 17, 2015, 09:29:21 PM
Pictured are a HD dropped spindle and a std stock spindle.  Note the HD takes a 1.25" rotor and the std takes a 1" rotor.  All 1973-1980 trucks had 1.25" rotors, the 1" rotor was introduced in 1981.  They take different calipers and bearings. Measurements are shown for comparison.  The drop spindle is 2.5"
