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 ranging from 27 spline all the way 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.
Spidertrax was founded in 1999 by two New Jersey guys who met each other in vocational school and who both were really into off-roading. Thomas Kingston is an mechanical engineer and Eddie Casanueva is a manufacturing engineer. Their engineering backgrounds combined with their love of off-roading is the key to Spidertrax innovative products. Eddie and Thomas custom produce mods for their own Jeeps. Then they run those mods up and down rock crawling trails until the mods fail. Then they meticulously examine the exact cause of the failure. They then incorporate a solution to the failure into the product design before starting mass production. The Jeep way of build-break-repeat is the very process that brings the quality to Spidertrax products. Shop Spidertrax Offroad Now
