While your pit crew, and back, are happy with the Spidertrax Drive Snout, this Drive Cover completes the assembly for rear axles. Not only will this Drive Cover keep your rear axle shafts where they belong, but our unique 2-piece design allows for quick access to those same shafts. Just four bolts like our standard covers and axle shafts can be pulled, inspected, and installed. This Drive Cover also comes with an upgraded o-ring design, perfect when running gear oil out to the Ultimate Unit Bearing. This Drive Cover is designed to bolt-on to Spidertrax Drive Snouts. Drive Snout sold separately.
