How the Swap Works
Quote and booking. Tell us your RAM (DS or DT, year, MDS or non-MDS) and how you use it. We confirm the package, options and timing.
Baseline dyno run. We record your RAM's stock power and torque on our dyno.
Engine swap. Cab lifted, 5.7 out, the new engine fitted with new gaskets, fresh coolant and oil.
Tune. ECU unlocked, then our own engine and transmission calibration, tuned on the dyno.
Final dyno run and road test. You get your before and after dyno sheet with the vehicle.
Time in the workshop: about 2 weeks for a 392 swap and about 3 weeks for a Hellcat Redeye swap, depending on any other repairs your RAM needs.
Engineering & Rego
Engineering is an optional extra. It isn't included in the swap prices above. If you want your swap engineered, ask us and we'll add it to your quote.
Both engines are Hemi V8s, but whether your swap needs a modification certificate depends on the engine and your state. A supercharged Hellcat Redeye adds forced induction, so it's very likely to need one. We'll tell you what applies to your vehicle before you commit.
