The durability of the 2500 series Ram is well documented, and, of course, the powerful Hemi is the motivator, But even that may not be enough for pulling serious weight. An ARH header system is exactly what you need to increase torque up to 30 ft. lbs. and rear wheel HP up 25 (before tuning). The system is 100% US made using all 304 Stainless Steel construction. Expect a great fit and easy installation from what is one of the best upgrades for your Ram. Want more? How about a great fit and easy install? We have you covered.
