2007-2012 Ram 3500 & 3500 6.4L Hemi AS68RC Transmissions & Transmission Parts

The Aisin AS68RC powering your awesome 2007-2012 Ram 3500, 4500, or 5500 with a 6.4L Hemi may be an upgrade over the base 66RFE transmissions, but it can still struggle to contain the awesome levels of power that your 6.4L Hemi Ram can hit with even the most basic performance tuning and bolt-on modifications. Tier One's built AS68RC transmissions can take massive amounts of horsepower, letting you stack on Ram performance upgrades without the fear of a transmission failure. Our performance AS68RC transmissions for the 6.4L Hemi Rams are a perfect solution for taking your HD Ram truck to the next level. Make sure to also check out our Dodge Cummins performance upgrades or our AS69RC built transmissions of the diesel HD Ram models. Contact Tier One with questions or for custom builds!
