Designed specifically for Ford Atlas axles, this collapsible spacer is exactly what you need to lock in the perfect pinion bearing preload during your next diff rebuild or pinion seal swap.
Because these washers are engineered to crush under a specific load to hold that precise bearing tension, they deform permanently once torque is applied. That means they are strictly a single-use part - if you’re pulling the pinion nut off, a fresh crush washer needs to go back on to prevent premature gear wear, annoying whine, or total diff failure down the road.
