Nolathane REV204.0052 Polyurethane Engine Mount Bushing 2-3/8 In. Wide x 2-3/16 In. Tall

The Nolathane REV204.0052 is a polyurethane engine mount bushing measuring 2-3/8 inches wide and 2-3/16 inches tall, engineered as a direct upgrade over soft OEM rubber bushings. Designed to work in conjunction with the existing OE rubber bushing, this motor mount bushing insert restores drivetrain responsiveness without requiring a full mount replacement.

Stock factory engine mount bushings are designed to minimize noise and vibration, but their softness allows the engine and transmission to rotate under load — resulting in vague throttle response and imprecise gear changes. The Nolathane REV204.0052 addresses this by adding polyurethane support that controls engine movement where it matters most.

Key Features:

• Dimensions: 2-3/8 in. wide × 2-3/16 in. tall
• Material: Premium polyurethane — resists oil, grease, ozone, and weathering
• Works with the OE rubber bushing — no full mount replacement required
• Reduces engine rotation under hard acceleration for improved throttle response
• Delivers more crisp and defined gear shifts in both automatic and manual transmissions
• Internal grease-compatible design for long-lasting performance
• Nolathane black finish for a clean, factory-style appearance
