Description
Overview:
The Ring Set (.25) Style B for Kohler Engines (OEM 24 108 28-S) is a genuine replacement ring pack for selected Kohler petrol engines, including CH23 and CH670. Made to Kohler's own tolerances from wear‐resistant materials, it renews the compression and oil‐control rings to restore cylinder sealing and engine efficiency. The .25 designation indicates a 0.25 mm oversize (0.010 in), intended for engines that have been re-bored or honed to the first oversize. By maintaining correct clearances and a reliable seal, this set helps recover compression, reduce blow‐by and oil consumption, and support smooth starting and consistent power. Suitable for workshops and DIY users maintaining lawn and garden equipment, generators, pumps and light construction machinery powered by the listed Kohler engines. As a Genuine Part, it offers assured fit and performance.
Key Features:
- Genuine Kohler part; direct replacement for OEM 24 108 28-S
- 0.25 mm (0.010 in) oversize for first‐oversize cylinders after re-bore or hone
- Style B ring configuration to match specified pistons on supported engines
- Precision‐matched compression and oil‐control rings for consistent sealing
- Durable, heat‐resistant construction for long service life

Common on ride‐on mowers, zero‐turns, garden tractors, generators, pumps, and compact construction machinery fitted with the applicable Kohler engines.
