This is an optional Schumacher Gear Differential Set. This set includes the necessary parts to assemble one complete gear differential, minus differential fluid. A gear differential provides longer running time between maintenance rebuilds, and with the use of steel gears, is super strong.
This differential is suitable for a wide range of conditions but is very good in high grip situations providing more forward drive and rotation. Recommended starting oils for Astro: 7000K front and rear. Clay/Low traction: 5000K front and rear.
