🔧 Premium Coilover Performance with FOX 2.5 Technology

This high-end kit features bolt-on FOX 2.5 factory race series coilovers with remote reservoirs for increased oil capacity and cooler operating temperatures. These coilovers are tuned out of the box for diesel engine applications and come with an optional DSC (Dual Speed Compression) adjuster, giving you full control over high- and low-speed compression damping with a simple twist of a knob.

💪 Heavy-Duty Upper & Lower Control Arms

Upgraded control arms make this more than just a lift—it’s a performance overhaul:

• Upper Control Arms: Fabricated from 1.5” OD x .120-wall tubular steel with indexed ball joint cups for corrected geometry and improved down travel.

• Lower Control Arms: Fully boxed and gusseted for maximum durability in extreme conditions.

• Maintenance-Free Bushings: Durometer-specific rubber bushings and greaseable ball joints ensure quiet operation and extended longevity.

🛠 Comprehensive Front-End Geometry Correction

The BDS coilover system includes everything you need to maintain factory-aligned steering and driveline angles:

• Multi-piece differential relocation brackets

• Upgraded sway bar links

• Heavy-duty hardware and crossmembers

• Custom u-bolt flip kit for added rear ground clearance

🚗 Rear Lift + FOX 2.0 Performance Shocks

In the rear, the factory blocks are replaced with taller lift blocks and upgraded FOX 2.0 IFP (Internal Floating Piston) shocks, delivering maximum travel and improved off-road response.
