Titanium Transmission to Engine Bolt Kit

The SpeedFactory Racing Titanium Transmission to Engine Bolt Kit provides a direct replacement for the stock 17mm-head transmission-to-engine bolts found on Honda and Acura B, D, and K series engines. This kit addresses the common issue of degraded or missing OEM hardware during engine swaps or transmissions repairs, ensuring a clean and secure installation. Crafted from ultralight Ti-6Al-4V (Grade 5 titanium), these bolts offer superior corrosion resistance, which is crucial for long-term reliability and ease of future removal compared to standard steel fasteners. The hollow-domed 6-point flange head design further contributes to weight reduction. The kits are precisely matched to engine families. B and D series applications receive five 65mm bolts. For K series engines, the kit includes six bolts: four 65mm and two 85mm bolts, specifically designed to fit the K bellhousing pattern correctly. The inclusion of varied lengths is a key detail that prevents installation issues often encountered when sourcing hardware separately. Fitment is based on the engine family (B, D, or K series) rather than the chassis, making it suitable for various Honda/Acura models with these engines, whether factory-installed or swapped, including FWD and AWD applications. Installation requires cleaning the threads in the block and case, applying a nickel-based anti-seize to the threads, and torquing to the factory service manual specifications. Avoid using impact tools for installation.
