Product Details
Grade 5 titanium key stock in the standard 1/4 x 1/4 inch square size, cut into 2 inch pieces and sold four to a pack. This is the keyway size that locks rear hubs, sprocket carriers and brake hubs to a 1.25 inch live axle on outlaw karts, jr sprints and quarter midgets, so one pack refreshes an entire rear end.
Keys sit right on the axle centerline, which makes them pure rotating weight. Moving from steel to Grade 5 titanium takes mass out of the driveline where it costs the most, and titanium will not rust a key into an aluminum hub the way steel does after a season of wet nights and pressure washing. You keep the shear strength to drive the hubs hard and pick up a little free acceleration on the way to victory lane.
- Material: Grade 5 titanium
- Key size: 1/4 inch x 1/4 inch square
- Length: 2 inch pieces
- Quantity: 4 keys per pack
- Weight: 9.5g (+/- 0.5g)
Fits any rear end running a full-height 1/4 x 1/4 square keyway. For thin-wall axles with a shallow keyway, the low-profile 1/4 x 3/16 key stock is a separate part. Cut each key to length to match your hub or sprocket carrier.
