Spidertrax Seal Insert SLIINSERT

Designed around NASCAR technology, this stretchy Seals-It brand seal insert performs like no other seal around. This one insert will work with shafts of diameters up to 40 spline and will keep oil where it belongs, inside your housing.

These seal inserts are designed to be installed in the Spidertrax High Performance Oil Seal Kit. Although one Seals-It insert is already installed in that kit, you can buy a second seal insert to "double seal" your shafts.
