4 Degree Cam Bushing 1/4 5 Pack-copper

The 4 Degree Cam Bushing 1/4 5 Pack from Comp Cams is an essential component for serious engine builders and performance enthusiasts looking to fine-tune cam timing and valve train geometry. These precision bushings allow you to adjust camshaft timing in small, controlled increments—critical for optimizing power delivery, fuel efficiency, and overall engine responsiveness. Whether you're dialing in a stock rebuild, a mild street engine, or a high-performance application, cam bushings give you the flexibility to dial in the exact timing curve your engine demands.

Each bushing in this 5-pack features a 1/4-inch bore and offers a 4-degree timing offset, manufactured from durable copper material that resists wear and provides reliable, repeatable performance through extended use. Comp Cams' engineering ensures tight tolerances and precise fit within your cam gear or timing sprocket, eliminating slop and maintaining consistency across multiple heat cycles and engine operation. The compact design—measuring 1.25 x 0.55 x 4.15 inches—integrates seamlessly into most street and race engine configurations, while the five-piece quantity provides spares for experimentation or future builds.

Professional engine builders, performance shops, and hands-on mechanics rely on these bushings when dialing in cam timing for peak torque production or top-end horsepower. Installation requires basic mechanical knowledge and access to a harmonic balancer or degree wheel for proper timing verification. The 4-degree offset makes this pack ideal for small-block and mid-size displacement engines where incremental adjustments yield measurable gains in throttle response, idle quality, or cylinder scavenging efficiency.
