BDS 5.5-Inch Radius Arm Lift Kit | FOX 2.0 Shocks | Ram 2500 4WD Gas 2014-2018

BDS 5.5-Inch Radius Arm Lift Kit | FOX 2.0 Performance Series Shocks | Ram 2500 4WD Gas 2014–2018 | SKU: BDS2101FS

The BDS 5.5-Inch Radius Arm Lift Kit (SKU: BDS2101FS) is a complete 5.5-inch front lift system for 2014–2018 Ram 2500 4WD gas models. This kit replaces the factory radius arms with heavy-duty BDS-engineered radius arms — correcting caster, reducing bushing bind, and maintaining consistent suspension geometry throughout the full range of travel at lifted height. The included FOX 2.0 Performance Series shocks provide improved damping control, heat resistance, and ride quality for towing, hauling, and daily use. Coil springs, track bar correction bracket, and all required hardware are engineered specifically for the Ram 2500 4WD gas platform.

Verified Fitment (OFAS Standard)

• Ram 2500 4WD Gas: 2014–2018

Does NOT fit: Ram 2500 diesel — different front suspension and engine bay configuration. Does not fit Ram 2500 2WD. Does not fit Ram 2500 2019 or newer — different platform and suspension architecture. Does not fit Ram 3500. Does not fit Ram 1500 or Ram 1500 Classic. Confirm model year and drivetrain before ordering.

Two Critical Fitment Gates

• 4WD only: This kit is engineered for 4WD Ram 2500. Does not fit 2WD models.
• Gas only: Coil springs and geometry are tuned for the gas engine platform. Does not fit diesel models — different front suspension and weight distribution.

Radius Arm Upgrade — Why It Matters

• Heavy-duty BDS radius arms: Replace factory radius arms with BDS-engineered heavy-duty arms — built for the increased stress of lifted height, larger tires, and work truck loads
• Caster correction: BDS radius arms maintain proper caster angle at 5.5-inch lift height — prevents steering wander and tire wear caused by incorrect caster on lifted trucks
• Reduced bushing bind: Improved arm geometry reduces the bind inherent in the factory radius arm design under articulation and load
• Consistent geometry: Maintains proper suspension geometry throughout the full range of travel — critical for drivability and long-term component durability
• Track bar correction: Included track bar correction bracket maintains proper axle centering at lifted height

Radius Arm vs. 4-Link — Suspension Architecture

• Radius arm upgrade (BDS2101FS, this listing): Replaces factory radius arms with heavy-duty BDS arms — retains the factory radius arm suspension architecture with upgraded components. For Ram 2500 4WD gas 2014–2018.
• 4-link conversion (BDS1676FS / BDS1677FS): Full conversion from factory radius arm to 4-link suspension architecture — more extensive modification, greater geometry correction. For Ram 3500 4WD gas 2019–2023.

FOX 2.0 Performance Series Shocks

• Improved damping: FOX 2.0 Performance Series shocks deliver significantly improved damping control over factory shocks at lifted height
• Heat resistance: 2.0-inch shock body provides greater oil volume for improved heat dissipation during extended towing and off-road use
• Ride quality: Tuned for the Ram 2500 4WD gas platform — balanced on-road comfort and off-road control
• FOX warranty: FOX 2.0 Performance Series shocks include a 1-year limited warranty

Installation Notes

• Professional installation required: Radius arm replacement and suspension lift is a complex modification — professional installation by a qualified suspension shop is required. Incorrect installation can cause handling instability, component failure, and safety hazards.
• Alignment mandatory: Full front-end alignment is required after installation. Do not drive on public roads before alignment is completed.
• Torque specs: All suspension fasteners must be torqued to BDS specifications per installation instructions.
• Break-in period: Allow FOX shocks to break in per FOX recommendations before aggressive off-road use.
• Tire sizing: Contact OFAS at 903-347-3875 to confirm maximum tire size for your Ram 2500 with this 5.5-inch lift before ordering wheels and tires.

Installation Warning

Professional installation required. Alignment mandatory after installation — driving without alignment after suspension modification is a safety hazard. Does not fit diesel, 2WD, or 2019 and newer Ram 2500. Does not fit Ram 3500.
