High-Quality Cam Cores

Quality Cores for Your Custom Production

Engine builders who prefer to finish grind their own lobes rely on LSM’s unground lobe camshafts (UGLs). Each core is created with precision, leaving only the final lobe grinding to you. We supply tens of thousands of UGLs to leading aftermarket suppliers and performance shops.

At LSM, every cam core starts as a billet core. That choice means stronger material, tighter tolerances, and proven reliability in demanding automotive applications and racing applications. Our billet designs withstand extreme spring pressures, aggressive profiles, and high-RPM conditions where cast cores fall short. Faster lead times and leaner inventory control make our cam cores as efficient as they are durable.

We commonly machine from premium alloys like 5150, 8620, and 4140, and can also produce camshafts from tool steel or other specialty materials to match your exact performance needs.

Why choose LSM for Cam Cores?

  • Proven Expertise: Decades of experience designing high-performance camshafts for weekend racecards and OEM programs alike.
  • Competitive Pricing: Volume runs of billet blanks rival the cost of cast cores.
  • Reliable Delivery: We can ship to your schedule in large or small batches with a nearly 100% on-time delivery record.
  • Flexibility: Any profile, firing order, or journal size can be tailored to your build.
  • Quality Materials: Induction-hardened and carburized cams from a variety of alloys (primarily 5150 and 8620).
  • ISO- and IATF-Certified: Our ISO 9001:2015 and IATF 16949:2016 certified processes guarantee consistency..
  • Lasting Performance: Precision machining delivers billet cam cores built for durability and repeatable accuracy.

Cam Cores for Racing and Automotive Applications

From drag strips to pro touring builds, LSM’s billet cam cores power some of the most demanding racing applications. Engine builders trust our cores to handle aggressive profiles, and extreme RPM ranges. Whether you’re working with flat tappet or roller lifter designs, our billet blanks provide the backbone for durable, high-output engines.

FINISHED CAMSHAFTS

Need more than blanks? LSM also produces fully ground camshafts, customized to your application. We can hold an inventory of your preferred camshaft core profiles, then finish grind them as you need them, so every cam is ground to exact specs without delays.

CAM CORES FOR ALL INDUSTRIES

LSM has built high quality cam cores for more than three decades. Our engineering expertise and machining capabilities allow us to adapt to any industry’s requirements while delivering performance you can count on.

CAM CORE PROTOTYPES

Testing a new design? Our cam core prototypes give you flexibility. Order a range of anticipated profiles and grind them in-house as you refine performance. Some builders also rely on LSM to stock multiple profiles, then request finished grinds as testing confirms the best setup.

Cam Core FAQs: What Builders Ask Us Most

Cam cores are the starting point for custom camshaft builds. Often called unground lobe camshafts, they give engine builders the flexibility to finish-grind the lobes to their exact specs.

  • Provide the foundation of a camshaft core
  • Leave final lobe grinding to the builder
  • Allow for precise tuning of performance needs

In short, cam cores put control of the final profile directly in your hands.

The material and process make all the difference. Billet cores are machined from solid bar stock, while cast camshafts are poured and shaped in molds.

  • Billet cores offer higher strength and precision
  • Cast camshafts can suffer from wider tolerances
  • Billet options support extreme spring pressures and aggressive profiles

For demanding builds, billet cores provide reliability that cast parts can’t match.

Yes. We produce cam core prototypes so builders can experiment before full-scale production.

  • Available in small runs or specialty profiles
  • Ideal for in-house grinding and testing
  • Option to stock multiple profiles for ongoing development

Prototypes help you refine performance before committing to large orders.

Our cam cores are trusted far beyond performance shops. They’re used wherever strength and precision matter.

  • Racing applications, from drag to endurance
  • Specialized custom builds

If reliability is essential, LSM cam cores have a proven track record.

Absolutely. Every LSM cam core can be engineered to match the builder’s exact performance goals.

  • Wide choice of materials, including tool steel and specialty alloys
  • Custom profiles, firing orders, and journal sizes available
  • Support for prototypes, small runs, and full production

This flexibility is why our cam cores are trusted across racing, OEM, and defense projects.
