4" 4-Link Suspension System (FOX Shocks) - 2014-2018 Dodge RAM 2500 4WD Diesel

Part # 1602HF

The newest addition to the 2500 Ram suspension line follows the same design as the 3500 Ram 4-Link conversion options.

Like our popular 2005-2014 Ford Super Duty systems, we replace the factory radius arm setup for 4-link system. The design starts with 2 massive frame brackets that provide the mounting points for the new upper and lower control arms. These brackets locate off of the factory radius arm brackets, no factory bracket removal required.

The new 4-Link brackets mount similar to the current radius arm relocation brackets, wrapping the frame and nesting in the factory radius arms mounts. As with our radius arm brackets, there is a minor amount of welding required to install the threaded frame insert (1 per side). This insert is necessary to provide the strongest possible mount. The new control arm positions at the frame create better suspension geometry and reduce caster change through wheel travel compared to the radius arm setup. This creates better handling and more controlled steering "feel", especially in rough terrain when the suspension is allowed to travel and articulate.

The large diameter, heavy-wall tubular control arms are formed for tire clearance when turning and position the axle slightly forward from stock to create more clearance to the rear portion of the front fenders.

In the rear the new 2014-17 2500s have a rear multi-link, coil spring suspension similar in design to that of the 09-up Ram 1500s. For this new system, the rear lift is accomplished with massive new 2.5" progressive rate coil springs. These new springs provide an amazing ride and are designed to stand up to any load the new 3/4 ton trucks were built to handle.

An axle mounted track bar relocation bracket repositions the rear track bar and centers the axle. Extended sway bar links keep the rear sway bar at the optimum operating angle. Replacement rear shocks round out the rear lift and provide that desired level stance.

We don't care if you jumped your truck off a cliff, lit it on fire, rolled it down a hill, installed Chevy parts on your Ford, or even if you didn't read the instructions and cross threaded a bolt with too many Ugga Duggas! This "no fine print" lifetime replacement warranty extends to cover all BDS hard parts and includes a lifetime warranty on bushings! Exclusions would be product finish and wearable items as described below. All warranties require the customer to provide a Proof of purchase including Name, product, purchase date and price paid.

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

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.
