LS Engine Mounts for 1984-1991 Chevy Corvette
If you are installing an LS V8 into a Chevy Corvette built between 1984 and 1991, the 1984-1991 Corvette LS Engine Mounts position the powerplant at the precise drivetrain angle required for OE 4L60E or 4L80E transmission fitment without any chassis modifications. By matching factory frame rail spacing and original transmission crossmember dimensions, the mounts preserve the Corvette's weight distribution and steering balance during cornering and heavy braking while eliminating chassis distortions and driveline stress. Crafted from thick steel plate in the United States and paired with polyurethane bushings, they resist flex under sudden torque shifts, absorb vibration to reduce cabin noise, and uphold chassis integrity over time. Complete hardware and a detailed guide let you bolt in the mounts using existing chassis holes, eliminating frame rail or tunnel trimming.
Exact Drivetrain Alignment for Classic Corvette Swaps
The 1984-1991 Corvette engine mounts are engineered to hold an LS powerplant at the exact angle needed for seamless mating to OE 4L60E or 4L80E transmissions. By matching factory frame rail spacing and the original crossmember footprint, the design maintains the Corvette's intended weight distribution and steering characteristics. This precise placement helps preserve suspension geometry, ensuring predictable handling and cornering balance identical to stock performance. With no chassis cutting or tunnel modification required, owners retain the structural integrity of the C4 frame and protect resale value. The result is a conversion that feels factory engineered rather than an afterthought.
Solid Steel Plate Base to Resist Engine Torque
Each mount bracket is fabricated from thick American steel plate to withstand the high output of modern LS engines under hard acceleration. Precision TIG welds join sections into a unified cradle that resists flex during abrupt throttle bursts or downshifts. This rigid foundation prevents misalignment of driveline components, reducing fatigue on U-joints and transmission housing seals over time. Strict quality control in US production ensures consistent material properties and weld penetration across every unit. Drivers will notice a rock solid connection between engine and chassis whether cruising or pushing on a road circuit.
Durable Polyurethane Bushings to Control Vibration
Performance grade polyurethane bushings replace traditional rubber to deliver long term resistance to heat, oil and compression set. Unlike softer compounds that sag or deform, these bushings preserve their shape through repeated temperature cycles, holding the engine precisely in place. The compound dampens harsh vibrations and keeps unwanted noise out of the cabin while still offering enough compliance to absorb shock loads on the frame. By maintaining alignment under peak torque, the design also reduces drivetrain lash and wear on connected components. The result is a smoother ride without sacrificing responsiveness.
Complete Installation Package for Seamless Fitment
The kit includes a matched pair of engine mounts, all necessary bolts, washers and detailed instructions to guide the installer step by step. By using the factory mounting holes, the process avoids drilling or trimming of frame rails and the transmission tunnel. This approach not only saves shop time but also ensures each bracket seats fully against the chassis for optimal load transfer. Whether tackling the project in a home garage or a professional workshop, the complete hardware package streamlines the LS swap and delivers confidence from start to finish.
A well-considered solution for your LS swap project, offering a precise fit and dependable performance.
