Elevate your Ford Super Duty diesel truck to the next level with this 9-inch 4-Link upgrade kit from BDS. It's got everything you need to give your truck the stance, performance, and capability it deserves, including diesel-specific Pro-Ride coil springs, 4-Link control arm conversion, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, bump stop extensions, stainless steel braided brake lines, NX2 steering stabilizer, and custom-tuned nitrogen charged shocks. 

With enough clearance for up to 40" tires, this kit is no joke (but it'll make your truck look seriously cool). Plus, it even comes with an indexing ring and new transmission crossmember for the transfer case, so you can still use the factory front driveshaft. And in the rear, you'll find full replacement Glideride leaf springs, u-bolts, brake line brackets, an overload spring, and a matching set of NX2 Nit

 

4-Link Conversion

Convert the factory stamped steel radius arms over to the BDS 4-link to optimize suspension geometry for better handling characteristics while adding strength and stability. This bolt-on upgrade utilizes high-strength 1/4-inch steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.

 

Pro-Ride Coil Springs

A pair of full-length, diesel-specific, Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.

 

T-Case Indexing

At this height, driveline adjustments are necessary to allow the use of the factory driveshafts so a precision-built transfer-case indexing ring featuring ARP-studs can clock the transfer case and improve the front driveline operating angle. Additionally, a high clearance transmission crossmember supplied to allow sufficient clearance.
