Description

The HKB Sports Boss Kit Hub Adapter (OR-205) is a crucial component for installing an aftermarket steering wheel onto compatible Mazda vehicles. Manufactured in Japan using either cast or billet aluminum, this adapter is built to endure the demands of sports and competition driving. Its construction prioritizes driver safety, incorporating a breakaway design to mitigate harm during severe impacts. The adapter is double drilled to accommodate a wide range of steering wheels, including those from Nardi/Personal and Momo/Sparco/OMP. Compatibility is specific and requires careful attention. This OR-205 hub adapter is designed for Mazda vehicles equipped with airbags, including models such as the RX-7 (FD3S), AZ-3 (EC5SA, ECPSA), MPV (LVEW), Cosmo (JC3SE, JCESE, JC3S, JCES), Sentia (HD5S, HDES), Familia (BHA3S, BHA3P, BHA6R, BHA7P, BHA7R, BHA8S, BHA8P, BHALP), Presso (EC8SE), Bongo Friendee (SGLW, SGLR, SGL3, SGL5, SG5W, SGEW, SGE3), Lantis (CBA8P, CBAEP), and Roadster (NA8C). However, several exclusions and important notes apply. For the RX-7 (FD3S) models from 10/91~12/98 and Sentia (HD5S, HDES) from 5/91~12/00, this adapter is not compatible with vehicles equipped with cruise control. The Roadster (NA8C) from 9/93~1/98 is not compatible with vehicles equipped with a MOMO OEM steering wheel. For certain Bongo Friendee and Presso models, alternative part numbers (OR-217 and OR-216 respectively) may be required, and buyers should confirm compatibility. Installation requires precise torque application, recommended between 3~3.5 kg/m, with careful attention to centering and holding the steering shaft to prevent slippage and potential damage. After-sale support does not include installation assistance, and compatibility is guaranteed only for JDM cars.
