4" 2025-2026 Dodge Ram 3500 4WD (w/Diesel Engine) Fox 2.5 Performance Coilover Lift Kit (4 Link) by BDS Suspension

The BDS 2157PPS 4-Inch Extended Travel 4-Link Coilover Lift Kit for diesel-powered Ram 3500 trucks combines premium FOX suspension performance with heavy-duty BDS components for improved ride quality, handling, and off-road capability. Designed for clearance of up to 37-inch tires, this system features FOX 2.5 Performance Elite DSC coilovers up front for excellent ride control and adjustability both on and off the road.

The factory front suspension is upgraded with a heavy-duty BDS 4-link system designed to reduce suspension bind while maintaining consistent caster and pinion angles throughout suspension travel. A forged adjustable track bar properly centers the front axle, while sway bar and brake line correction components maintain proper suspension operation at the increased ride height.

For increased suspension travel, BDS includes a 10-bolt transfer case indexing ring that corrects driveline geometry and allows additional front suspension droop. Rear lift is provided by a high-strength fabricated lift block system with longer U-bolts. Rear shock choices include FOX 2.5 Performance Series HTO shocks with position-sensitive Hydraulic Top Out rebound control or FOX 2.5 Performance Elite reservoir shocks with DSC compression adjustment.

The kit can also be configured with factory-style rubber bump stops or upgraded FOX 2.0 Factory Race Series hydraulic bump stops for additional bottom-out control during aggressive off-road use. With its combination of FOX coilover technology, BDS 4-link geometry, and extended-travel design, this system delivers a premium suspension upgrade without sacrificing everyday drivability.
