COMP Cams Camshafts and Valvetrain Parts

Shop COMP Cams parts for a camshaft upgrade, valvetrain refresh or coordinated engine build at Black Ops Auto Works. Explore HEMI HRT camshaft choices, selected Coyote and GM applications, lifters, valve springs, pushrods, rockers and timing components. Choose the combination around your engine and intended operating range.

Camshafts and Matched Build Plans

HEMI references distinguish VVT and non-VVT applications, stages, NSR designations and master-kit contents. Coyote and other engine-specific profiles have their own requirements. Compare the actual cam specifications and supplied components with your cylinder heads, induction and intended use; a stage number does not describe the complete combination.

Lifters and Conversion Packages

Compare hydraulic flat-tappet and roller references for the correct engine and camshaft architecture. Selected Evolution and Xtreme Energy DLC listings, non-MDS HEMI kits and GM DOD-delete packages address distinct projects. Review complete conversion scope, companion components and calibration requirements where specified.

Springs, Pushrods, Rockers and Timing

Build a coordinated valvetrain using the specified spring setup, retainers, locks, seals and clearances. Match pushrod length and rocker geometry to the assembled engine. Timing-chain, phaser and measuring-tool references support specific configurations; review what the kit supplies and what the installation still requires.

Frequently Asked Questions

Is a higher stage number always a better choice?

Choose the actual cam profile for the complete engine combination and intended use. Stage alone does not establish suitability.

Does NSR apply to every camshaft in this collection?

No. Review the designation and requirements of the exact camshaft and application.

Are flat-tappet and roller lifters interchangeable?

Select the lifter design specified for the camshaft, engine architecture and any engineered conversion.

Is every DOD-delete package a complete conversion?

Review exact contents and all companion hardware and calibration requirements for the actual engine.

Can I choose pushrods using the original engine specification?

Measure the assembled combination and required geometry, especially after changes to heads, camshaft, lifters or deck dimensions.
