Product Description

The MaxTrac K853300-4 is a complete front forged 4-link upgrade kit - both driver and passenger sides - designed specifically for 2017-2022 Ford F-250 and F-350 Dually trucks in a 4WD configuration. It replaces the factory radius arm setup on both sides with a true 4-link suspension system, delivering improved caster adjustability, superior axle control, and enhanced ride quality over any standard radius arm drop bracket kit, regardless of brand.

Built from aircraft-grade forged aluminum with chromoly axle sleeves and spherical rod ends, this complete kit provides a precise, adjustable bolt-on upgrade that installs in approximately 2.5 hours with no permanent modifications to the vehicle. Caster can be dialed in without dropping the arms, simplifying the alignment process. By purchasing both sides as a single kit, owners get a complete and matched upgrade at a lower combined cost than buying each side separately.
