RZR 170 Engine Crankcase Spacer-Collar #10

If you've ever split a GY6-style case, you know how these little collars like to hide in the parts tray — or worse, fall into the drain pan. This OEM crankcase spacer collar (Polaris #0454570) is diagram reference #10 in the RZR 170 engine crankcase assembly, and it's one of those parts you don't think about until it's gone.

Spacer collars locate hardware and set precise spacing inside and around the crankcase. Substituting random washers or leaving one out during reassembly isn't the move — incorrect spacing can cause misalignment, loose hardware, and problems that show up a hundred miles later when everything's already buttoned up.

This is a genuine Polaris part, so fit is exact: correct ID, OD, and length, straight from the factory spec. If you're doing a big bore kit, case work, a stroker build, or a full teardown on your RZR 170, add the crankcase hardware to your order now — nothing kills momentum on a build like waiting a week for a small collar.
