Pinion Crush Sleeves

Pinion Crush Sleeves - 8-3/4" differential. Note: This is ONLY for the 489 casing. The 741 or the 742 case did not need a crush sleeve....

Solid Spacer - 8-3/4 substitute for 489 case crush sleeve.For those that may want another option – we have a solid spacer that can be substituted into a 489 case, which is better way to go for several reasons: The solidspacer holds its dimension better under high-load use; it can be re-used multiple times; and it allows the drive yoke to be removed and replaced without the possibility of altering the gear setup. Most importantly, however, the solid spacer can be installed normally during the trail assembly, and if the mesh pattern checks out, you are done.
