Energy Suspension GM LS Series Motor Mount Conversion Kit

The Energy Suspension GM LS Series Motor Mount Conversion Kit is purpose-engineered for builders tackling a GM LS engine swap into a chassis originally designed around an older-style three-bolt motor mount configuration. This product line delivers precise fitment, drivetrain stability, and long-term durability — eliminating the guesswork and compromises associated with adapted or generic mounting solutions.

Hyper-Flex™ Polyurethane Technology

Every kit in this lineup is built around Energy Suspension's proprietary Hyper-Flex™ polyurethane compound — engineered to outperform conventional OEM rubber in virtually every measurable way. Hyper-Flex polyurethane resists harsh fluids, oils, and road chemicals, and will not dry out, crack, or deteriorate under the extreme heat cycles common to performance engine bays. The result is a motor mount that maintains its integrity and performance characteristics far longer than standard rubber alternatives.

Key Features:

• LS Swap-Specific Engineering — purpose-built to adapt GM LS series engines to chassis using early conventional three-bolt motor mount configurations
• Hyper-Flex™ Polyurethane Cushions — highly resistant to oil, grease, chemicals, and extreme temperatures for lasting durability and consistent performance
• Reinforced Steel Construction — polyurethane cushions paired with heavy-duty coated steel adapter plates for a rigid, reliable installation
• Reduced Engine Movement — minimizes drivetrain flex and unwanted engine shift under hard acceleration for more precise power delivery
• Complete Hardware Included — all necessary bolts, nuts, washers, and fasteners included for a clean, professional bolt-on installation
• Limited Lifetime Warranty — backed by Energy Suspension's confidence in their materials and U.S.-based manufacturing

Energy Suspension is a globally recognized leader in performance polyurethane suspension and drivetrain technology, holding over nine U.S. patents and bringing decades of in-house engineering expertise to every product. Each component is manufactured to exacting tolerances — from initial design and material formulation through molding and hardware selection — ensuring consistent quality across the entire product line. Whether the goal is a restomod cruiser, a street/strip machine, or a dedicated track build, the Energy Suspension GM LS Motor Mount Conversion Kit series provides the durability and precision every swap deserves.
