Set precise pinion bearing preload and protect your crownwheel and pinion gears from premature wear with the Blackline English Axle pinion crush washer. Positioned on the pinion shaft between the inner and outer tapered roller bearings, this collapsible steel spacer compresses smoothly as the pinion nut is torqued down to lock in the exact bearing preload required for quiet, efficient operation.
Because crush washers are strictly single-use items, fitting a fresh Blackline spacer is essential whenever you replace a pinion oil seal, swap out worn bearings, install a new Blackline limited-slip differential, or change your final drive ratio.
