RZR 170 Transmission Counter Shaft #23

The counter shaft is the backbone of your RZR 170's gearbox — the counter gear rides on it, and every bit of power headed to the rear wheels passes through this shaft. If yours is showing wear at the bearing surfaces, scored journals, or damaged splines, replacing it with anything less than OEM is asking for a repeat teardown.

This is the genuine Polaris OEM counter shaft, part number 0452526, position #23 on the RZR 170 transmission cover parts diagram. It also cross-references to AEON part #2342139A-000 — AEON is the OE manufacturer behind this engine platform, so you're getting exact factory spec on material, hardening, and machining tolerances.

Doing a full trans refresh? Grab the matching counter gear (#22, part 0452527) plus fresh transmission bearings and the output shaft seal while the cases are open — it's the same labor either way, and you'll only want to do this job once.
