The Apex Chassis KIT375 ProLock Steering Kit rebuilds the steering linkage on a 2017-onwards Ford F-250 or F-350 Super Duty with extreme-duty steel. Super Duty trucks haul, tow and plough at weights that flex the factory tie rod and drag link - the classic route to death wobble and steering that never feels planted. This kit replaces the linkage with massive DOM steel assemblies, oversized forged ends, proprietary set-screw jam nuts and ProLock washers, so the geometry you set is the geometry that stays. It is a genuine Apex Chassis part, imported to the UK.
Confirm your truck's year and that it is not a wide-track model before ordering - fitment shown is manufacturer reference. The oversized components sit larger than factory, so if you run a dual steering stabiliser, check clearance and mounting against this kit before committing. Plan a full alignment after installation and torque the ProLock hardware to spec so the locking system does its job.

It removes the linkage flex and self-loosening that drive wobble on these trucks. Inspect track bar, ball joints and damper as part of the job - the cure sticks when the whole system is sound.
No - wide-track models are excluded from the application. Confirm your truck's spec before ordering.
Keyway washers and set-screw jam nuts mechanically stop the rods rotating, so the alignment you set survives hard use instead of working loose.
