Solid cast tappets/lifters for the Cummins 4BT four-cylinder. At 1.300" diameter they're much wider than the 1.10" tappets in many 4BT engines, that extra surface area spreads the load between cam and tappet to reduce lobe and lifter wear, which matters on today's low-zinc oils.

- Spreads load to reduce lobe and lifter wear

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.
