What Is an Engine Camshaft Degree Wheel Kit?
Engine camshaft degree wheel kits are among the most important specialty tools in any serious engine builder's arsenal. A camshaft degree wheel tool is a specialized instrument used in the engine building process to precisely set the camshaft position relative to the crankshaft. Without this critical step — known as "degreeing the cam" — even a high-quality performance camshaft can fail to deliver its rated power and efficiency.
How Does a Camshaft Degree Wheel Work?
The degree wheel is attached to the front of the engine crankshaft, and a pointer is positioned at the top dead center (TDC) of the number one cylinder. The camshaft is then installed, and the degree wheel is rotated until the camshaft reaches the desired position. This is typically done using a dial indicator to measure the lift and duration of the camshaft lobe and then adjusting the camshaft position accordingly. Even a few degrees of misalignment can have a profound effect on engine operation and performance.
A complete camshaft degree wheel kit includes everything you need to verify the specs and alignment of your performance camshaft — most include a degree wheel, a pointer, a dial indicator with a stand, valvetrain checking springs, piston stops, adapter bushings, hardware, and instructions, all organized in a handy carrying case. This all-in-one approach ensures that both seasoned engine builders and first-time DIYers have everything on hand to get the job done right.
What to Consider When Shopping for a Degree Wheel Kit
- Heads-on vs. heads-off: Some kits are designed for use with cylinder heads installed on the engine block, while others require heads-off access. Confirm which configuration your build requires before purchasing.
- Wheel diameter: Larger diameter wheels (11"–18") are easier to read precisely and are preferred for engine stand use, while smaller 9" wheels are more practical when the engine is in the vehicle.
- Engine compatibility: Universal kits work with most popular V8 platforms, but engine-specific kits — such as those designed for GM LS or Ford Coyote engines — include the correct crankshaft sockets and adapters for a more accurate, secure fit.
- Included components: Look for kits that include a dial indicator, TDC locator, cam checking fixture, and a foam-padded storage case to protect your investment.
