Spidertrax High Performance Outboard Oil Seal Kit (For 3-1 2 IN Spider 9)
SKU: S06P SLI312D
Beginner — under 30 min
Description
Each kit includes a steel seal housing and two rubber seal inserts. The steel housing is intended to be welded onto the wheel side of your Spider 9 housing tube. This allows the housing tubes to function as a reservoir for increased oil capacity, a common modification in Ultra4 racing. For front steering axles, this seal can also serve to keep dirt and debris out of the housing tubes. The seals accommodate Spidertrax axle shafts from 31-35 spline, and the steel housing fits 3-1/2" Spider 9 housings.
