Ford 10.5" Crush Sleeve
The Ford 10.5" crush sleeve (also known as a collapsible spacer or pinion preload sleeve) is a vital single-use component for setting accurate pinion bearing preload during differential regears, rebuilds, pinion seal replacements, or yoke swaps on the Sterling 10.5" axle. It compresses reliably under pinion nut torque, providing consistent preload for optimal gear mesh, reduced wear, and dependable operation under heavy loads.
Standard in Ford Super Duty trucks (F-250, F-350, and some F-450/F-550 models from 1999 onward, plus earlier applications), this crush sleeve should be replaced anytime the pinion assembly is disassembled to prevent preload loss or premature failure. Available standalone or in installation kits, it's a key piece for towing, work, or performance builds on these heavy-duty axles.
The Ford 10.5" crush sleeve is a collapsible spacer essential for setting pinion bearing preload during differential regears, rebuilds, or pinion seal replacements on Sterling 10.5" axles. Replace it whenever the pinion assembly is disturbed for accurate setup and durability under heavy loads.
