UMI Performance 90071 SBC Polyurethane Engine Mount Kit for 1978-1988 GM G-Body
$109.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1978-1988 Buick Regal, Chevrolet Malibu, Monte Carlo, and El Camino, GMC Caballero, Oldsmobile Cutlass, and Pontiac Bonneville.
The UMI Performance 90071 engine mount kit is engineered to eliminate the excessive engine movement common with aged factory rubber mounts. Designed specifically for Small Block Chevy (SBC) engines in the 1978-1988 GM G-Body platform, this kit utilizes high-performance polyurethane bushings to stabilize the engine. By significantly reducing engine deflection under load, these mounts improve throttle response and ensure more consistent torque transfer to the drivetrain while maintaining the durability required for performance street and track use.
- Direct-fit for SBC-equipped 1978-1988 GM G-Body vehicles
- High-durometer polyurethane bushings for superior durability and engine control
- Reduces engine movement to improve power delivery and clearance
- Rugged construction replaces prone-to-failure OE rubber mounts
- Manufacturer Part Number: 90071
