9900ZV Ring Set 99.00mm for Wiseco 99.00mm Piston Ring Set

Ring Set for Wiseco 3162VS

This Wiseco 3162VS ring set is a 3.162 inch piston ring replacement kit for two-stroke and four-stroke engine rebuilds, restoring the compression seal between piston and cylinder wall.

Overview

This 3162VS ring set for Wiseco pistons uses the 3.162 inch bore dimension stamped into the part number to identify the exact application. Rings wear, lose tension, and lose the seal that makes compression, so fitting a fresh ring set at rebuild time is standard practice when a cylinder comes apart. This ring set for Wiseco is aimed at engine builders and owners rebuilding a top end who want the right diameter rings matched to the part number rather than a guess. The 3.162 inch sizing and the 3162VS code make it straightforward to cross-check against your piston before ordering.

Built For Performance

• 3.162 inch bore sizing identified by the 3162VS part number
• Ring set intended for a matching piston, so ring width and profile suit the intended groove
• Faced and finished to seat against the cylinder wall during break-in
• Manufactured by Wiseco for its own piston applications
• Sold as a set for one piston

On-The-Job Use

• Top end rebuilds when a piston is replaced and the rings go with it
• Compression refresh on a tired engine before the next season
• Shop work where the old ring set has lost tension, scuffed its face, or been damaged in removal
• Correcting ring gap after a bore measurement and hone

Good To Know

Q: How do I confirm this ring set matches my piston? A: Match the 3.162 inch bore and the 3162VS part number against the piston you are installing. Piston part numbers and bore size are the two details that lock in fitment, so check both before ordering.

Q: Do I need to check ring end gap before assembly? A: Yes, end gap should be measured in the cylinder bore and adjusted to your engine builder's spec before the piston goes in. Rings that are simply installed out of the box can seize when the engine reaches temperature.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
