Universal Bushing 1.5ODx 2.5L w/1/2in Bolt Hole

The Universal Bushing 1.5ODx 2.5L w/1/2in Bolt Hole by PROTHANE is a critical suspension and drivetrain component designed to isolate vibration and reduce noise in vehicle mounting applications. Whether you're rebuilding a control arm, engine mount, or transmission support, this polyurethane bushing replaces worn OEM rubber components that have degraded over time. As an enthusiast mechanic, you'll appreciate that upgrading to a quality aftermarket bushing restores precision handling and eliminates the clunking and creaking that develops in aging vehicles.

PROTHANE's polyurethane formulation outperforms factory rubber by resisting heat, oil, and UV degradation—extending service life well beyond the original bushing. The 1.5-inch outer diameter and 2.5-inch length suit a broad range of mounting points, while the 1/2-inch bolt hole accommodates standard metric and SAE fasteners common across domestic and import platforms. Polyurethane bushings are stiffer than rubber, which increases suspension responsiveness and reduces lateral play in worn mounting points, translating to tighter steering feel and more predictable brake feedback during spirited driving or load-bearing applications like towing.

This universal bushing is ideal for frame-on-body restorations, suspension refreshes, and powertrain mount repairs on light trucks, muscle cars, and classic vehicles where OEM replacements may be unavailable or cost-prohibitive. Installation is straightforward—press or bolt the bushing into your existing mounting bracket using a shop press or engine hoist, depending on your setup. Before ordering, verify your mounting hole diameter matches the 1/2-inch specification and confirm overall dimensions fit your application's envelope. Pair with a full bushing kit to transform your vehicle's feel and eliminate decade-old vibration patterns.
