LS Engine Mounts for 1984-1991 Chevy Corvette
The 1984-1991 Corvette LS Engine Mounts are engineered to position LS engines at the correct drivetrain angle in a C4 chassis without any chassis modifications. Matching factory dimensions for the frame rails and the OE transmission crossmember, they maintain the Corvette's original weight distribution and cornering balance. Constructed from heavy gauge steel and fitted with durable polyurethane bushings, this setup absorbs vibration and resists flex under load. Installation arrives complete with hardware and step by step instructions so you can bolt in the assembly with confidence.
Preserving C4 Corvette Handling with Exact Engine Geometry
The LS mounts are machined to factory frame rail and transmission crossmember dimensions, so the engine sits at the ideal drivetrain angle without cutting the chassis. By matching original mounting points, the design keeps weight distribution and suspension geometry true to the engineers' intent. This precise alignment reduces stress on driveline components and maintains stable steering balance under acceleration, cornering and braking. No chassis modifications means you preserve the C4 structure and handling character built into every model.
Polyurethane Bushing Technology for Engine Stability
Each mount uses a polyurethane bushing that resists heat, oil and compression set far better than conventional rubber. This material absorbs and dissipates engine vibration without allowing excessive movement under load, reducing noise in the cabin and minimizing wear on mounting surfaces. Over repeated acceleration and deceleration cycles, the bushing maintains consistent alignment to prevent drivetrain lash and fatigue. The result is a smoother ride feel and long material life even in spirited driving or track duty.
Comprehensive Bolt-In Hardware Kit for Streamlined Installation
The installation kit arrives with every bracket, bolt and washer needed to complete the swap without extra parts runs. Clear step by step instructions walk you through each attachment point, eliminating measurement guesswork and trial fitting. Since the components fit directly into factory holes, there is no need for drilling or trimming the frame rails or transmission tunnel. This complete kit approach saves time and ensures the mounts engage full metal surface for secure support.
American Made Steel Plates Deliver Lasting Durability
Fabricated from heavy gauge steel, the mount plates resist flex and torsion generated by high torque LS engines. Precision TIG welding secures each seam for a rigid cradle that holds the powerplant firmly, even under high load shifts. Domestic production enables tight quality control at every step, ensuring consistent material strength and fit. The result is a support system capable of withstanding repeated heat cycles and torque spikes for the life of your Corvette conversion.
