RAM 1500, 2500, 3500. Hemi 5.7 V8, Hemi 6.4 V8, Pentastar 3.6 V6, EcoDiesel 3.0 V6, 6.7 Cummins inline-6. ZF 8-speed (1500), 6.7 Cummins with Aisin AS69RC HD transmission.
RAM diagnostics use AlphaScan / wiTECH or compatible Stellantis tools. We have the right kit for modern RAM, including the Cummins-specific INSITE software for diesel work.
For the Hemi 5.7 lifter tick (MDS), we replace failed lifters with updated OEM Mopar parts. The aftermarket lifters often fail again within 30,000 miles. We use OEM. For severe lifter failure, the cam may need to be replaced too — we’ll diagnose and quote in writing.
For the EcoDiesel CP4 fuel pump, we follow the same approach as the Power Stroke 6.7 CP4: proactive replacement on high-mileage trucks, OEM Bosch parts, no CP3 conversions (federal compliance).
5th gen. Hemi 5.7, 6.4 (Rebel TRX), Pentastar 3.6, EcoDiesel 3.0. ZF 8-speed.
6.7 Cummins (250–370 hp depending on year). 68RFE auto, Aisin auto, G56 / G80 manual.
6.7 Cummins HO (HD trim, 400 hp). Aisin AS69RC. Heavy-duty drivetrain.
6.4 Hemi V8. 8-speed automatic. Less common than diesel but well-supported.
Pentastar 3.6 V6, 3.0 EcoDiesel (older). Cargo van service, fleet.
3.0L V6 diesel in 1500. CP4 fuel pump, EGR, DEF system service.
If your vehicle is doing any of these, bring it in. None of them is guaranteed to be the part you might think — that’s why we diagnose first.
The 5.7 Hemi has a Multi-Displacement System (MDS) that deactivates 4 cylinders under light load. The lifters that handle the cylinder switching can fail, causing a tick at idle that gets worse with age. The fix involves replacing the failed lifters (sometimes the cam too if damage has spread). Typical cost: $2,000–$4,000.
Yes — extensively. See our Cummins page. We have INSITE diagnostic software, OEM parts, and we service every generation of the 6.7 Cummins from 2007.5 to current.
Yes. The 3.0L EcoDiesel in older RAM 1500 has a CP4 fuel pump issue similar to the 6.7 Power Stroke. We service routine work and address the CP4 proactively when warranted.
Yes. The Aisin AS69RC in RAM 3500 HD diesel is a robust transmission that needs disciplined fluid service. We use the manufacturer-spec fluid and follow Aisin procedures.
Typically 25–35% below dealer rates for the same work using OEM Mopar parts.
