BDS 4-Inch Lift Kit with FOX 2.5 Coil-Overs - 2007-2014 Chevy/GMC SUVs 4WD
Transform your 2007-2014 Chevy Avalanche, Suburban, Tahoe, or GMC Yukon 1500 into the ultimate off-road performer with BDS Suspension's comprehensive 4-inch lift kit featuring premium FOX 2.5 Factory Race Series coil-over shocks. This complete system delivers enhanced ground clearance, improved suspension travel, and clearance for aggressive 33-inch tires while maintaining exceptional on-road comfort and handling.
FOX 2.5 Factory Race Series Coil-Overs - The Ultimate Upgrade
What separates this kit from basic lift kits is the inclusion of proprietary FOX 2.5 Factory Race Series coil-over shocks designed specifically for your application. These aren't off-the-shelf shocks—they're engineered in partnership with BDS to deliver bolt-on performance with:
- Increased Suspension Travel: Extended shock travel allows your suspension to articulate over rough terrain without bottoming out
- Smooth Bore Technology: 2.5-inch seamless steel body provides consistent damping and fade-free performance
- Application-Specific Valving: Custom-tuned to handle the weight and dynamics of lifted full-size SUVs
- Adjustable Eibach Racing Springs: 3.0 Eibach coil springs fine-tuned for optimal ride height and load capacity
- Premium Finish: Zinc-plated and double-clear coated body with black-anodized CNC-machined 6061-T6 billet aluminum components
The result? A lifted truck that soaks up the roughest off-road terrain while maintaining smooth, controlled on-road comfort.
High-Clearance Design - Maximum Ground Clearance
BDS's tried-and-true high-clearance design philosophy is built into every component of this kit. Unlike budget lift kits that simply add height, the BDS system strategically relocates components for:
- Maximum Ground Clearance: High-arched 1/4-inch thick steel crossmembers keep vulnerable components away from obstacles
- Off-Road Protection: Heavy-duty skid plates and multipiece differential relocation brackets protect critical drivetrain components
- Strength and Durability: Robust construction handles the abuse of serious off-road use
Corrected Suspension and Steering Geometry
Lifting your SUV changes suspension angles and steering geometry. BDS addresses this with precision-engineered components:
- CNC-Machined Ductile Iron Steering Knuckles: Correct steering geometry at the new ride height while maintaining ESC (Electronic Stability Control) system compliance
- Full-Length Replacement Strut Shocks: Properly valved for lifted applications
- Sway Bar Drops: Restore proper sway bar geometry
- Bump Stop Extensions: Prevent suspension over-travel
- Brake Line Brackets: Ensure brake lines aren't over-extended
- CV Spacers: Maintain proper CV axle angles
