This is a XRAY 38T Differential Pulley with Labyrinth Dust Cover, and is intended for use with the XRAY 305003 and 305004
aluminum ball differentials. This molded-composite 34T diff pulley with
XRAYs innovative Labyrinth Dust Cover diff protection system has been
carried over from the previous T1/T2 platforms where it has been very
successfully used for many years. The special internal labyrinth design
of the diff covers prevents any dirt, debris, or carpet fibers from
getting into the differential and as such reduces servicing and ensures
the longest life of the differential.
