Low friction straight pin ball joints are designed to fit spindles with straight-through 3/4 in mounting holes. The straight pin design allows height adjustment by relocating the internal shim stack for more accurate, precise changes versus swapping the entire pin. This is the Small K772-reference Screw-In housing with a 1 in to 2 in adjustable pin. Take-apart, greasable, and rebuildable. For off-road use only. Note: machining of most standard spindles from tapered to straight-through mounting holes is required for use with this style ball joint.

Compatibility
ALL56872 cross-references to the Small K772-style screw-in upper ball joint housing used by Allstar and Moog. It requires a spindle machined for a straight-through 3/4 in mounting hole and adjusts from 1 in up to 2 in longer than standard by relocating the shim stack rather than changing pins.
FAQ
What is the adjustment range on the ALL56872 ball joint?
It adjusts from 1 in up to 2 in longer than standard length by relocating the internal shim stack, allowing height and roll-center changes without swapping the entire pin.
What housing style does ALL56872 use?
It uses the Small K772-reference screw-in housing, matching the Allstar and Moog K772 cross-reference used on upper ball joint applications.
Does this ball joint require spindle modification?
Yes. Because it uses a straight pin design, most standard spindles must be machined from a tapered mounting hole to a straight-through 3/4 in hole before installation.
