Spidertrax Filler Cap
Without question, the Spidertrax Axle Filler Assembly Kit is the sharpest, most well designed setup in the off-road market, making it the ideal solution for custom off-road housing build-ups. Our Spider engraved 6061T6 billet aluminum filler cap has an o-ring seal to keep oil where it belongs and keeps the filler cap from loosening up. In addition, our double anodize protection will keep your filler cap from corroding even in the harshest terrain. Our weld-in steel sleeve has a large 1-5/16" diameter opening making gear inspection and filling easy. Our Spidertrax Axle Filler Assembly Kit contains one steel sleeve, aluminum cap, and o-ring.
