Bring the Identity 4-Link series to your 2017–2022 Ford F450 / F550 Super Duty 4WD with the Stryker 3 1/2" to 8" RAD Tube 4-Link Upgrade Kit. Identity Series 4-link arms, badged HD drop brackets and all hardware come in the base kit, with a traction bar and center cradle available by part number.
Why Choose the Stryker F450 RAD Tube 4-Link Upgrade Kit?
- Drop brackets mount outside – rather than going up inside the factory radius arm pocket, Stryker’s bracket mounts outside for added width and strength.
- U.S. steel, ¼” and up – all steel is U.S. made and at least ¼”, larger in some places.
- Fabricated in Maryville, TN – all 4-link arms and drop brackets are made in house on Stryker’s HSP (high speed plasma) Star Lab machine.
- Traction bar and cradle options – base kit only, with a traction bar, or with a traction bar and the new Identity Series floating center cradle.
- Identity styling – badged HD drop brackets for Stryker’s signature look.
