JTR Precision Engines custom performance heads for Dodge Magnum 5.2L and 5.9L engines. |
|
67,000 mile Dodge 5.9L receiving new JTR 360 package. |
|
These newer engine compartments are crowded but this one can be done in-frame with a good low mileage bottom-end. |
|
Custom porting and cylinder head building, note the screw in studs, guideplates, beehive springs and porting on the left-hand head. The right-hand head is a stock 5.9L 360 Magnum head. The left-hand head is a JTR custom built EQ head for Magnum Engines. |
|
The newly designed ports and chambers are more efficient and support more power than the factory designed castings. They also have thicker deck surfaces to eliminate the cracking problem that occurs on these heads between the intake and exhaust seats. |
|
The new heads, camshaft, lifters and full roller rockers are all installed and prelubed. |
|
This intake has been custom machined with shorter runners that have been profiled for more peak power and a broad power curve. |
|
Custom machined and high temp coated “kegger” manifold for Dodge Magnum engines. |
|
One of our custom engine packages here at JTR Precision Engines is the 318, 360, 408, or 426 Dodge Magnum engines. Is your Ram or Dakota leaving you wishing for more? We can cure that for you with one of our custom engine packages. Our heads outflow the R/T heads at a fraction of the price and are not crack prone like the factory heads. We also sell custom tunes for your truck computer that can support any combination you can think of. These engines also make great replacements for the older Mopar LA series engines with a carburetor package so that you don’t have to worry about all of the injection. |
