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.

Many of the products we sell are made to order, imported or custom built, so a lead time may apply. If you need a part urgently, contact us before ordering and we will confirm the expected delivery timeframe and process.
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.
