LS Engine Mount Kit, large bushings, universal

Heavy-Duty Engine Mount Kit (LS & HEMI)

We’re confident that this kit will handle the scrutiny of your friends when they’re checking out your build, as well as any power you can throw at it. The very same kit is trusted by Don Schumacher Racing on their 1150hp HEMI dyno cart, so you know it’s built to withstand high horsepower and demanding performance. It works seamlessly for both LSand HEMI engines, making it a versatile choice for builders.

This versatile engine mount kit is compatible with various LS engine variations, including LS1, LS2, LS3, LS6, LS7, and the more recent LSX and LSA models, as well as the HEMI engine.

Precision Engineering:
The main plate is laser-cut from 1/4" pickled & oiled (P&O) mild steel, ensuring high durability and resistance to deformation under heavy loads. The 3/16" P&O gussets and frame plates add rigidity to the entire setup, giving your engine the solid support it needs.

Energy Suspension Performance Bushings:
Our kit features large, high-performance 1-3/4" wide, 1-5/8" OD urethane bushings from Energy Suspension, a trusted name in polyurethane components. These bushings are designed to absorb vibrations and deliver a smooth ride, while still providing the secure engine stability needed for high-performance builds. The frame plates measure 6" from the bushing center to the opposite end, with the bushing bolt center positioned 3-3/8" from where the mount sits on the block. This allows for precise alignment and easy installation.

Heavy-Duty Mounting:

• The bolt hole pattern is 4-7/16" x 3-1/4” and slotted slightly, perfectly aligned for LS and HEMI applications.
• The kit is available either precision TIG welded or as a ready-to-weld component kit for those who prefer to customize the assembly.
• Includes all grade 5 zinc-plated hardware, bushings, engine brackets, and frame plates to ensure a complete and hassle-free installation.

Additional Reinforcement Option:

For those seeking extra strength, the optional “frame filler plate” add-on includes two #27804 rectangular plates, which can be welded between the frame plates for additional rigidity and reinforcement, ensuring your setup is rock-solid for any demanding applications.
