Aluminum steering Block for CRC Ultra-tune front end. Made to fit the CRC 1/8th inch axle that uses the stronger 1/8th x 5/16th wheel bearing.

Use the CRC #3020 for the axle. Accepts CRC and A12 bushings and collars.

Note regarding the steering block bushings:

If you use the 3021 CRC machined engineering plastic bushings, these are a precise fit for the CRC Ultra-tune kingpin at 5mm. For the over-sized 5.05mm A12 kingpins, you can use stock A12 bushings or you may need to ream the CRC engineered composite bushings to obtain the fit you desire.
