2017-2019 Ford F250/F350 6" Radius Arm Suspension System 3 Leaf - Rear Block - NX2 -

Take your 2017-2019 Ford Super Duty F250 and F350 diesel truck to the next level with this 6-inch radius arm lift kit from BDS. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 38 Inch Tires.

Up front the lift kit includes diesel-specific Pro-Ride coil springs, heavy-duty replacement radius arms, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets, and custom-tuned nitrogen charged shocks.

At this height, the transfer case needs to be indexed to allow use of the factory front driveshaft so an indexing ring and new transmission crossmember are supplied. In the rear this kit utilizes a high-strength fabricated lift block, longer u-bolts, brake line brackets and a matching set of NX2 Nitro or FOX Performance shocks.

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.

HD Radius Arms

In place of the factory stamped steel radius arms BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights along with an OE-style rubber bushing at the frame mount for smooth, quiet, service-free operation.

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.
