Warranty note: Hamilton only warranties their cams when run with Hamilton tappets and springs.

Fits: 1989-2018 Dodge/Ram 5.9L/6.7L Cummins, 12V and 24V. (Drop-in fit requires no more than .018" piston protrusion and the correct valve face depth, otherwise requires machining.)

Break-In & Install

Drop-in clearance: 12V, no more than .018" piston protrusion, at least .055" valve face depth, standard head gasket, 99 intake centerline. 24V, no more than .018" protrusion, at least .038" valve face depth, standard gasket. If you don't meet clearance, run an oversize head gasket or cut valve reliefs. Always check clearances.

We always recommend new lifters when changing a cam. Follow this break-in to protect the lobes:

  • Apply a liberal amount of quality assembly lube to the camshaft.
  • Do not let the engine start without oil pressure, we suggest not changing the engine oil until after the engine has been started.
  • On a new engine, pack assembly lube into the oil pump and prime the oil filter so the cam gets oil fast.
  • Disconnect the fuel system and crank with the starter until you read oil pressure or see oil at the rocker arms. Don't run the starter more than 10 seconds at a time.
  • Once oil pressure is verified, start the engine and run it at 1,200-1,500 RPM for five minutes, then shut down.
  • On a new engine, retorque the head (expect .003"-.004" more gasket crush, which changes valve lash, readjust the valves). Then you're cleared to use it.

At Full Send Diesel, we don't just sell parts. We stand behind them. Hamilton Cams machines their Cummins camshafts, valvetrain, and hard parts right here in the USA, and their commitment to performance and reliability lines up with how we build trucks.

We don't just carry Hamilton as a brand. We run their parts in our personal trucks, our in-house builds, and every giveaway truck we put together. If it's not good enough for our own trucks, it's not good enough for our customers. Hamilton Cams has earned our trust, on the street and on the dyno.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
