Skyjackers transfer case index ring kit prevents front driveline issues on your 5-8.5 inch lifted F250 / F350. With larger lifts it is necessary to index the transfer case to allow the front driveline to reconnect and eliminate any vibrations. This transfer case index ring kit retains optimal spline engagement and is clocked to be used with up to 8.5 inches of lift height. A heavy duty high clearance transmission crossmember and transmission mount bracket are supplied to retain sufficient clearance. These are powder coated to provide an extremely durable protective barrier to prevent corrosion. Complete with high-grade mounting hardware.
