The ProLock system uses a machined keyway, keyway washer, and a jam nut with integrated set screws, designed to help secure the drag-link connection against the loosening that is common in OE and conventional aftermarket drag links. The reversible design and included stainless taper sleeve address steering stabilizer mounting on lifted trucks. Two hard stops before ordering: this kit is not compatible with wide-track axles, and it is not compatible with the BDS Adjustable Trackbar.
