SBC Poly Engine Mounts

The SBC Poly Engine Mounts from UMI PERFORMANCE deliver the vibration isolation and structural support critical for small-block Chevrolet builds. Whether you're running a stock 350 or a heavily modified 383, engine mounts directly control drivetrain harmonics, chassis flex, and component longevity. These mounts address the weak link in many budget builds: inadequate motor isolation that allows excessive engine rocking under acceleration, braking, and load transfer. Designed for street machines, drag cars, and weekend warriors, the SBC Poly Engine Mounts absorb engine movement while maintaining proper geometry for exhaust clearance and accessory belt tension.

UMI PERFORMANCE engineered these mounts with polyurethane elastomer compounds that outperform both OEM rubber and street-use solid mounts. Polyurethane provides superior damping of low-frequency vibrations while resisting oil, heat, and ozone degradation—critical durability factors in engine bays routinely exposed to 180+ degree heat cycles and aggressive additives. The material's composite structure locks engine position within tighter tolerances than rubber, reducing unwanted lateral movement that stresses frame welds, transmission bearings, and steering linkage. The mounting hardware is engineered for direct bolt-in fitment on small-block Chevrolet configurations, with precisely sized bushings that maintain OEM clearances for alternator, power steering, and intake manifold accessories.

These mounts suit any serious SBC platform—Chevelle, Nova, Camaro, or third-gen F-body builds where engine isolation directly impacts ride quality and component survival. Installers appreciate the straightforward bolt-on design that requires no frame modifications or custom fabrication. Drag racers benefit from reduced weight transfer during violent launches, while street builders eliminate rubber creep that gradually shifts engine position, throwing timing cover clearances and radiator fitment. Verify your application against your specific block and frame configuration before ordering; SBC mounts are not interchangeable across all mounting locations or model years.
