Bruiser Conversions began its life as Jeff’s Jeep Yard in 1984, a salvage yard for Jeep vehicles. After a few years of reselling parts, Jeff established a fabrication division. Initially, he needed it to reconstruct sheet metal for bodies, repair structural issues with frames, and rebuild crossmembers and motor mounts. Necessity turned into a passion and Jeff started customizing the shape of vehicles, bringing them to life in a reimagined form. Form and function are the foundations of a great vehicle. Jeff started specializing in conversions using Chevy small block engines with modern electronic control systems, integrating them into the Jeep Wrangler CJ models of the era, and it grew from there. He developed a process to create reliable, high-power engine kits for his reimagined vehicles. Through the years, Jeff has led his team building bespoke restorations, restomods, hot rods, street rods, muscle cars, jeeps, mud trucks, amongst other creations, that perform just as good as they look. Bruiser Conversions’ clients love it, and we do too. Almost four decades along, and Bruiser Conversions is as passionate about our work as ever—excited for new coachbuilding projects, the new technologies to integrate into our builds, and the new opportunities and experiences the vehicle’s owner will get to enjoy. The seamless, factory-style functionality complements the kick-ass performance and award-winning form that makes these vehicles amazing to drive and highly collectible. It is the nearly-40-years of ideation, design, fabrication, and integration experience that our clients trust to turn their desires into drivability.

From the 8HP70 and 8HP75 to the 8HP90 and 8HP95 — we have the capability to support the right ZF 8HP transmission for your build.

Every application is different. Whether you’re building a street cruiser, high-horsepower restomod, off-road rig, or something built to take serious abuse, we can match the transmission to your power goals and intended use.

Our 8HP conversion kits are built around making these transmissions work in applications they were never originally offered in — with OEM-style control, drivability, and performance.

8HP70 • 8HP75 • 8HP90 • 8HP95

Built around your application. Built to support your power goals.
