Submit a question

  • What are the benefits of a Hamilton Cams Flat Tappet Conversion Kit?

    Thoroughbred Diesel | 8/10/2026

    Key System Benefits

    • No Tuning Needed: Operates safely on stock factory calibration.
    • Emissions Compliant: Keeps all factory emissions equipment intact (49-state SEMA certified; not legal in California).
    • Performance Gains: Users often see quicker turbo spool, cooler EGTs, and minor fuel economy improvements.
    • Removes Needle Bearings: Eliminates factory roller bearing failure points that can score cam lobes and fill the engine with metal debris.

    Watch this quick video on the benefits:

  • Will this fix the Cummins lifter tick and cam failure?

    Thoroughbred Diesel | 8/7/2026

    Yes, it removes the OEM needle-bearing roller wheel assembly entirely at the source.

    Replaces it with Diamond-Like Carbon (DLC) coated steel flat tappets that have no small bearings to break and contaminate engine oil.  

  • What Parts Come in the Kit?

    Thoroughbred Diesel | 8/7/2026
    • Camshaft: A forged steel 178/208 profile cam designed to improve efficiency.
    • Tappets: Diamond-Like Carbon (DLC) coated steel flat tappets.
    • Pushrods & Rockers: Heavy-duty upgraded pushrods and adjustable rocker arms with DLC-coated trunnions (required because flat tappets need manual lash adjustment).

  • Emissions Legal?

    Thoroughbred Diesel | 8/7/2026

    Yes, the kit is SEMA-certified for 49-state emissions (not legal in California).

  • What does a Hamilton Cams Flat Tappet Conversion Kit come with?

    Thoroughbred Diesel | 8/7/2026

    What Comes in the Kit:

    • Forged 178/208 efficiency camshaft
    • Diamond-Like Carbon (DLC) coated steel flat tappets
    • Heavy-duty upgraded pushrods (3,500 lbs buckling force)
    • Adjustable rocker arms featuring DLC-coated trunnions

  • When you swap this cam and lifters do you still use the same oil as I did with the hydraulic lifters or what is recommended?

    Scott Johnson | 2/28/2026

    It is important that you use 15-40 oils in non-winter conditions or 5-40 sub-zero.

  • Do you offer installation service for the Hamilton kit

    Dave | 9/28/2025
    • Cam removal tray and installation kit.

  • Does the kit come with everything to convert it. The 2021 truck came in with broken lifter

    David Perry | 9/26/2025
    • The kit will include the camshaft, tappets, pushrods and rocker arms. Add the cam removal tray and install kit.

  • Is the Hamilton solid tappet cam conversion kit for the 19-24 Cummins on back order and if so what is the expected eta?

    Evan Parks | 11/19/2024

    Yes, 2 week lead time at this time.

  • Does this kit come with the tray and magnets to remove and install the lifters ?

    Ryan | 9/26/2024

    No

  • Hello what is the difference from these flat tops and hydraulic lifters? I have a 2024 cummins just got the first oil change last week and my lifters started ticking bad. Now I’m waiting on them to open it up and look at them. If I have to replace them would you recommend installing these? Thanks

    Humbert Magana | 9/3/2024

    Simply a flat surface to ride the camshaft as opposed to a roller, yes they have worked well so far.

  • Do you offer the tools required as a kit with the cam kit

    David | 5/27/2024

    No
