Wilwood Starlite 55 five-bolt drive flange O-ring style (without bolts) adds a sealing boss and O-ring to create a leak-proof seal, eliminating the need for gaskets or sealers to retain differential oil. Machined from 7075-T6 alloy with a 24-spline count, the flange kit includes the end plate and screws while flange attachment bolts are omitted on 'L' part numbers for customers supplying their own hardware.
