Superlift Suspension K125F 4-Inch Lift Kit with Fox 2.0 Series Shocks and Replacement Radius Arms

The Superlift Suspension K125F is a 4-inch suspension lift kit engineered specifically for 2014–2018 Dodge Ram 2500 4WD trucks equipped with a diesel engine. This kit delivers a substantial lift while maintaining ride quality and drivability through the inclusion of premium Fox 2.0 Series performance shocks and heavy-duty replacement radius arms.

At the heart of this kit are the replacement radius arms, which correct the front axle geometry that is altered when lifting a solid-front-axle truck. By repositioning the axle to factory-spec geometry, the replacement arms reduce bump steer, improve caster angles, and preserve proper handling characteristics after the lift is installed.

Key Features:

• 4-inch front and rear lift designed for 2014–2018 Dodge Ram 2500 4WD diesel models
• Fox 2.0 Series shocks provide high-performance damping and a smooth, controlled ride at ride height
• Replacement radius arms restore correct front axle geometry and caster angles after lifting
• Engineered to accommodate larger aftermarket tires for improved off-road capability and appearance
• All hardware and mounting components included for a complete installation
• Designed to work with the factory front solid axle configuration of the Ram 2500

The Superlift K125F is an ideal choice for Ram 2500 diesel owners who demand both elevated ground clearance and uncompromising ride performance. Superlift's reputation for heavy-duty truck suspension solutions makes this kit a trusted upgrade for work trucks and off-road applications alike.
