Hooker BlackHeart Transmission Mount

Hooker BlackHeart Transmission Mounts: Engineered for High-Performance Engine Swaps

When it comes to engine swap builds, every component in the drivetrain chain matters — and the transmission mount is no exception. Hooker BlackHeart has established itself as one of the most trusted names in platform-engineered swap solutions, and their lineup of transmission mounts reflects the same precision thinking that defines the entire BlackHeart system.

Polyurethane Construction Built for Serious Power

Hooker BlackHeart transmission mounts are constructed of durable polyurethane to handle the stress and vibration of high-horsepower applications while still lasting longer than rubber mounts. This is a key differentiator for builders who are pushing power beyond factory levels. Traditional rubber mounts tend to deteriorate under extreme heat cycles and torque loads, but polyurethane holds its shape and damping characteristics far longer under demanding conditions. Available in both black and red colorways, these mounts let enthusiasts add a subtle touch of style without sacrificing function.

A Fully Integrated Engine Swap Ecosystem

What truly sets Hooker BlackHeart apart in the transmission mount category is how these components are designed to work as part of a comprehensive, system-level solution. This LS/LT swap transmission mount adapter kit is part of the most comprehensively engineered system of mounting components, headers, and exhaust systems available for this application. Rather than piecing together mismatched parts, builders can rely on BlackHeart components that are purpose-designed to work together.

The transmission mount adapter kits are comprehensively designed for use with Hooker BlackHeart transmission crossmembers in specific LS engine swap applications, and when used as instructed, provide engine/transmission inclination angles optimized for U-joint working angles and component clearances. This level of engineering detail eliminates guesswork during installation and reduces the risk of driveline vibration or misalignment — common headaches in DIY swap builds.

Broad Vehicle and Transmission Compatibility

Hooker BlackHeart polyurethane transmission mounts cover various 1958–2004 GM Cars, 1966–90 GM Trucks, and 1980–1995 Jeep CJ/YJ/Wagoneer applications. On the transmission side, the system supports a wide range of popular gearboxes. Adapter kits facilitate installation of GM 4L60-4L70, Tremec TKO 500/600, and TTR-3550 transmissions in multiple LS swap vehicle applications using Hooker BlackHeart engine mounting brackets and transmission crossmembers. Additional adapter kits extend compatibility to the GM TH400, 200-4R, 4L80E, 4L85E, and even the Tremec T56 Magnum for manual transmission enthusiasts.

CAD-Designed Precision and Finish Quality

Hooker BlackHeart crossmembers and mounts are designed as part of a fully-engineered LS swap mounting system, CAD designed to provide an optimized balance of weight, stiffness, and strength. A semi-gloss black powder coat finish provides an attractive, corrosion-resistant appearance that holds up in the engine bay long after the build is complete. Whether you are tackling a first-gen F-body LS swap or a classic GM muscle car build, Hooker BlackHeart's transmission mounts deliver the fitment and durability that demanding projects require.
