Short Boss Kit, 40mm Length

The Works Bell Short Boss Kit for Rapfix is a steering wheel hub crafted from durable billet aluminum, measuring 40mm in length. This design is intentionally 30mm shorter than a standard boss kit, offering a more compact profile. This product is specifically designed for Momo steering wheel pitch and is intended for use with the RX-7 FC3S models that do not have an airbag. All hardware required for installation is included with the kit. Works Bell manufactures these components with strict quality assurance practices under NAPAC guidelines, ensuring durability for sports and competition applications. The design also incorporates a breakaway feature to mitigate driver injury during severe impacts. Proper installation is crucial, especially with tapered tooth designs, to prevent slippage and potential cracking under load. Ensure the steering shaft is free of grease and the boss kit is mounted flush before applying torque. The maximum torque specification is between 3-3.5 kg/m, and specific torque wrench operation is recommended for accuracy. Compatibility is based on maker information for JDM cars, and fitment is not guaranteed. Please conduct your own research before purchasing. The kit is compatible with various Mazda RX-7 FC models, including FC3C and FC3S with the 13B-T engine from 10/1985 to 10/1992, and FC3S models from 10/1985 to 11/1991. It is explicitly stated to be for RX-7 FC3S models without an airbag.
