Remanufactured Cummins 5.9L 24-valve common-rail diesel long block for 2003 to early 2007 Dodge Ram 2500 and 3500 pickups. Zero miles, built to order, free shipping. $1,500 refundable core charge (added as a separate core item at checkout).

Rockers and pushrods included. Reconditioned rocker arms and pushrods are part of the long block, so you don't have to transfer them from your old engine. Some long blocks on the market leave them out.

Build time: usually 7-10 days, plus shipping (contact us for current availability).

Fitment

Dodge switched to the 6.7L Cummins in January 2007, so a 2007 Ram can have either engine. Only the 5.9L trucks are covered.

Confirm your engine

• VIN 8th digit: C or 6 = 5.9L, covered. A (2007) = 6.7L, not covered.
• Early or late 5.9: 2003-early 2004 engines (305 hp or lower on the engine decal) use different pistons and injectors than 2004.5-2007 engines (325 hp). Another tell: a 2004.5 and later turbo has an electronic wastegate with a wiring connector. We match the build to your VIN.

Send us your VIN with your order to confirm fitment.

Break-in

A diesel's piston rings seat under load, not at idle. Following these steps is required to keep your warranty.

• Before the first start: fill with conventional (non-synthetic) 15W-40 heavy-duty diesel oil, pre-fill the oil filter and pre-lube the engine. Fill the cooling system.
• Prime the fuel system: turn the key to run the lift pump several times before cranking. The high-pressure system bleeds itself, so never open the high-pressure fuel lines. Do not use starting fluid.
• First start: don't rev it. Run at 1,500-2,000 rpm until the thermostat opens, check oil pressure and look for leaks, then top up the coolant. Keep this first run short (about 5-10 minutes).
• First 100 miles: don't idle for more than 5 minutes at a time.
• First 500 miles: drive under a moderate to heavy load (towing or hauling) and vary your RPM and load. Avoid long, unloaded cruising at a steady speed, and don't rev the engine while parked, since that doesn't load the rings. Watch your gauges and check the oil level often.
• At 500 miles: change the oil and filter.

Long idling or light-load driving during break-in can glaze the cylinders, which leads to oil burning and low power. See our break-in procedure for more.

Warranty, core and performance parts

Warranty: 1-year unlimited-mile warranty on the engine only; labor is not covered. Optional 3-year extended warranty available for $1,500 (includes labor coverage at $50/hr). See our Warranty & Refund Policy. Add the 3-year extended warranty to your order.

Core charge: $1,500, refundable, added at checkout as a separate core item. You have 30 days to return your old engine (core). We pay the return freight: when it's ready, we email you a return label, and you ship the core back on the same pallet your new engine came on.

Performance parts: we do not blueprint engines. We can install custom or performance parts you supply (you pay for the parts and shipping them to us; no extra installation charge), but this waives the 1-year warranty.
