DoctorDiff Sure-Trac II is a fully machined, forged steel 8.75" differential which operates similar to an Eaton True-Trac.

The Sure-Trac II incorporates 6 helical (worm) gears instead of 4 for maximum strength and smooth, quiet operation.

Use conventional 85 W 140, GL-5 grade gear lube. Friction modifier additive is not necessary.
