      Construction and Appearance. Constructed with EN36 racing-grade internal components and housed in a case made from durable 8620 chrome-nickel-moly steel, the differential is case hardened for extended life and strengthened resistance to wear. The finish is industrial and engineered for longevity rather than aesthetics.
