At the heart of the systems you'll find BDS's tried and true high clearance IFS technology designed to offer more ground clearance while improving the suspension, steering, and driveline geometry. This paired with FOX 2.5 factory series coilovers offers vastly superior damping performance to soak up the harshest terrains offroad while offering comfort on your daily commute. The coilovers are pretuned and ready to install right out of the box featuring a dual speed compression (DSC) adjuster on the reservoir to allow for easy tuning of the high-speed and low-speed compression damping by hand, without the need for special tools. To mount the coilovers BDS supplies a bolt-on bracket that installs on the frame in the shock mount location along with a weld-in support gusset is used to reinforce the upper mount.
In addition to replacing the factory torsion bars, the upper control arms (UCA) are upgraded to improved strength, travel, and accommodate the new coilovers. The uppers are new performance series upper control arms designed specifically for this system to integrate with the 2.5 coilovers. The arms are fabricated from large 1.5" OD x .120-wall tubing, fully welded and gusseted for the highest quality, strength and durability. The factory cast steel lower control arms are retained with the addition of a robust lower coilover mounting bracket. Along with the coilover conversion, these 6.5" coilover systems include a pair of one-piece laser cut high clearance crossmembers, CNC machined ductile iron steering knuckles to correct steering angles, heavy duty front skid plate and differential skid plate to increase protection, multipoint differential relocation brackets to secure differential and correct CV axle angles, CV spacers, and longer sway bar links. In the rear, your options are a 5" rear block and u-bolt kit or replacement GlideRide rear leaf springs with built-in overload leaf. Either option will level the stance and are paired with FOX 2.0 performance series IFP shocks to pair with the front coilovers for impressive performance wherever your the adventures lead you.

Wearable Parts | Limited Lifetime Warranty
BDS NX2 Series Shocks and BDS/Fox Performance Series Shocks: Shock oil seals are not covered by this Limited Lifetime Warranty because they are subject to wear over time and use. At BDS's discretion, leaking shock seals less than 2 years from date of purchase, free from contamination, damage, or abnormal seal wear due to misuse can be considered for repair or replacement under warranty. A shock absorber is a wear item and over time will experience diminished damping resistance due to normal component wear. This is not a defect in material or workmanship and is therefore not warrantable. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion.
Fox Proprietary Shocks and Coil Overs: Fox Proprietary parts are covered by their warranty and are not included in the BDS Warranty. BDS may offer to assist with the warranty of defective product, at our discretion. Other warranty concerns should be handled through the Fox Service program. Leaking shock seals less than 1 year from date of purchase, free from contamination, damage, or abnormal seal wear due to misuse can be considered for Warranty. FOX service information can be found here: https://www.ridefox.com/service.php?m=truck
Ball Joints and Tie Rod Ends: These items are subject to normal wear over time. However, Ball Joints and Tie Rod ends less than 3 years from the date of purchase, that have been properly greased, maintained, and do not show signs of abnormal use can be considered for warranty.
BDS Suspension's obligation under all warranties is limited to the repair or replacement, at BDS's option, of the defective material. BDS will cover the cost of ground shipping on warranty items, and a return shipping label if we require the warranty part to be returned to us.
