JB Raceworks OTK Bumper bushing and weight bolts tool

JB Race Works OTK Bumper & Ultra-Thin Weight Bolt Tool

Make tightening OTK bumper bushings quick and easy with the JB Race Works OTK Bumper & Ultra-Thin Weight Bolt Tool. It’s machined from aircraft-grade 6061 aluminum and anodized for durability, and it works with a standard 1/2" ratchet. A 1/2" to 3/8" reducer is included, so you can use it with a 3/8" ratchet too.

The same tool also tightens our JB Race Works Ultra-Thin F1-Style Weight Bolts, so one tool handles two jobs in your pit box.
