2007.5–2009 Dodge Ram 2500 & 3500 6.7L Cummins Steering Gearboxes & Braces

Eliminate excessive steering wheel play, put an end to vague on-center wander, and restore tight, responsive control with premium 2007.5–2009 6.7L Cummins 3rd Gen steering boxes and stabilization components from Full Force Diesel. Heavy-duty Ram 2500 and 3500 trucks working under severe commercial workloads, hauling heavy gooseneck trailers, or rolling on oversized all-terrain tires subject their steering gearboxes and sector shafts to immense rotational and side-load stress. Over years of heavy-duty use, internal sector gears wear out, housing bores stretch, and factory frame horns flex, leading to a terrifying amount of freeplay in the steering wheel. Upgrading to heavy-duty remanufactured steering gearboxes, reinforced internal valving, and stabilizing sector shaft braces locks your front end down for good.

Advanced Steering Precision: Heavy-Duty Gearboxes and Sector Shaft Braces

Transitioning away from a worn, sloppy factory steering box to upgraded stabilization hardware completely transforms your truck's highway tracking:

  • Heavy-Duty Replacement Steering Gearboxes: Rebuilt with larger internal pistons, upgraded recirculating ball bearings, and tighter internal tolerances to eliminate dead zones in the steering wheel and deliver crisp, immediate feedback.

  • Sector Shaft Stabilization Braces: Engineered to tie the steering box sector shaft directly to the frame rail, eliminating the destructive frame flex and shaft deflection that causes premature gearbox failure under heavy loads.

Rugged Cast-Iron Housings and Secure Mounting Hardware

Our selection of steering components features heavy-gauge hardware engineered to handle extreme lateral force:

  • High-Strength Cast-Iron Housings: Built from thick-wall, stress-relieved iron designed to resist cracking and internal housing distortion when fighting against heavy front axle loads.

  • Corrosion-Resistant Seals and Fitting Kits: Equipped with high-pressure fluid seals and precision-machined O-ring port fittings to prevent power steering fluid leaks and maintain reliable hydraulic pressure.

At Full Force Diesel, we carry the rugged, street-tested mechanical hardware and machine-shop-certified components your transitional 3rd Generation inline-six needs to track straight and true. Explore our complete selection of 2007.5–2009 6.7L Cummins 3rd Gen steering boxes, sector shaft braces, and steering hardware above to secure your truck's handling today.
