RAM SRT10 Gear Ratio Upgrade Kits
Your RAM SRT10 comes from the factory with a 4.10 ratio in 2004 or a 4.56 in 2005–2006. We offer a wide variety of gear ratio upgrade kits to enhance your vehicle’s performance.
Why Upgrade Gears?
Upgrading your gears maximizes power and torque during acceleration and at lower speeds, ideal for racing. It transfers some of the power from the top end (around 150 mph) to the lower end, making your vehicle feel as if it gained about 50 HP on takeoff!
