Overview

The Works Bell Short Boss Kit for Rapfix is a steering wheel hub adapter made from billet aluminum. It features a length of 63mm, which is 17mm shorter than a standard boss kit.

Show original supplier description

Engineered to be 17mm shorter than standard boss kits, this 63mm long adapter is specifically designed to integrate aftermarket quick-release systems, such as the Rapfix, and various sports steering wheels onto your Toyota's steering column. This boss kit maintains compatibility with the Momo steering wheel pitch and shares the same vehicle compatibility as the standard Boss Kit 537. It is manufactured under strict quality assurance practices by ASEA and NAPAC, ensuring extreme durability for sports and competition applications. The design includes a breakaway feature to reduce driver injury in severe impacts. Installation requires careful alignment to prevent slippage and potential cracking. The maximum torque specification is between 3-3.5 kg/m, with specific instructions for accurate torque wrench usage. The seller notes that compatibility information is provided by the maker for JDM cars only and fitment is not guaranteed; customers are advised to conduct their own research. A comprehensive list of compatible Toyota models and their corresponding engine codes and production years is provided, covering vehicles from 1996 to 2024. This includes a wide range of models such as the Allion, Camry, Celica, Corolla, Crown, Estima, Mark II, MR-S, RAV4, and Vitz, among others.
