Maxtrac Suspension, the leader in bolt-on suspension solutions, introduces its most advanced system yet for 2017-up Ford Super Duty trucks. At the center of this innovative system are Maxtrac?s massive forged aluminum upper/lower link arms, which are clear anodized and fitted with spherical rod ends that allow for on-vehicle adjustability. Each rod end is threaded into a robust chrome moly sleeve, which is then threaded into the arm to add strength and preserve thread integrity for a lifetime of service. We also offer a factory arm drop kit. Both kits come with linear-rated coil springs, lift blocks and all installation brackets/hardware with either MaxTrac or Fox 2.0 shock absorbers.
