2003-2008 Ram 1500 5.7L Hemi Parts & Accessories

Your 2003-2008 Ram 1500 may be no spring chicken, but the 5.7L Hemi V8 under its hood is more than capable of standing toe-to-toe with modern trucks, provided you have the right drivetrain support. At Tier One, we specialize in waking up these older Rams. We offer parts and accessories to transform your truck into an aggressive build capable of tearing it up on the street, track, or trail. While we carry Ram 5.7L Hemi tuners, cold air intakes, and lift kits, our true specialty lies in fixing the weak point of these trucks: the 545RFE transmission. Our built transmissions and rebuild kits are designed to hold more power than stock, fixing common failure points so you can run bigger tires or forced induction without fear. If your factory transmission is slipping or you are pushing serious horsepower, a stock replacement just won't cut it, so take a look at our 2003-2008 Ram 1500 5.7L Hemi Complete Transmissions. The factory torque converter is designed for comfort, not speed, so get better launches and towing performance with one of our 2003-2008 Ram 1500 5.7L Hemi Torque Converters. The 545RFE transmission runs hot, especially when towing or turning big tires, so keep your fluid temps in check with our 2003-2008 Ram 1500 5.7L Hemi Transmission Coolers. Rough shifting or delayed engagement is often caused by the valve body, but you can restore smooth operation with our 2003-2008 Ram 1500 5.7L Hemi Valve Bodies. Finally, whether you need a deep transmission pan for extra fluid capacity or rebuild components, we have the parts you need in our section of 2003-2008 Ram 1500 5.7L Hemi Transmission Parts.
