• Utilizes factory upper coil bucket reinforced with support gussets for enhanced strength
• Lower mounts weld directly to the axle housing with cross support gussets for the factory TracK Bar bracket
• Dirt Logic 4.0 Resi Coilovers feature stainless steel bodies for maximum corrosion resistance
• Remote billet aluminum reservoirs improve heat dissipation and shock performance
• Rear Dirt Logic shocks included for balanced suspension upgrade
• Supports tire sizes up to 38/13.50R22 with appropriate wheel fitment and minor trimming
• Designed for wheels ranging from 17x9 to 22x10 with 5-inch backspacing
• Provides excellent off-road damping while maintaining a smooth highway ride

Construction & Design:

The Fabtech 7-inch Radius Arm Kit is engineered with durability and performance in mind. The system retains the factory upper coil bucket, which is reinforced with gussets to withstand the increased stresses of lifted suspension setups. The lower mounts are custom-fabricated to weld securely onto the axle housing, featuring cross support gussets that maintain the integrity of the factory TracK Bar bracket.

The Dirt Logic 4.0 coilovers included in this kit are constructed with stainless steel bodies, offering superior corrosion resistance for longevity in harsh environments. The remote reservoirs are crafted from billet aluminum, enhancing heat dissipation and shock consistency during extended off-road use. This combination of materials and design ensures the suspension components remain reliable and effective under demanding conditions.

Installation & Fitment:

Installation of the Fabtech Radius Arm Kit requires moderate fabrication skills, including welding and drilling. The process involves welding the lower mounts to the axle housing and drilling approximately 10 holes for proper fitment. Estimated installation time is between 5 to 6 hours, making it suitable for experienced installers or professional shops.

This kit is compatible with a wide range of Ram 2500 trims from 2014 through 2018, including Big Horn, Laramie, Laramie Limited (2014–2015), Laramie Longhorn, Limited (2016–2018), Lone Star (2014–2015), Outdoorsman (2014–2016), Power Wagon, SLT, and Tradesman models. It supports larger tire and wheel combinations with minor trimming required for optimal clearance.

What's Included:

• Fabtech 7-inch radius arms with reinforced upper coil bucket support
• Lower mounts with cross support gussets for axle housing
• Dirt Logic 4.0 Resi Coilovers with stainless steel bodies and remote billet aluminum reservoirs (front)
