2933TD Ring Set 74.50mm for Wiseco

Ring Set, 74.50mm for Wiseco

This Wiseco-style piston ring set measures 74.50mm and is built to seal the combustion chamber and control oil along the cylinder wall in a matching bore engine.

Overview

This 74.50mm ring set is a replacement piston ring assembly for engines running that bore size, helping bring back compression and cut down on blow-by. The rings seat in the piston grooves to seal combustion pressure and manage the oil film on the cylinder wall. This ring set suits rebuilders and riders doing a top end refresh on a single cylinder machine.

• Multi-ring set covering compression and oil control positions
• Precision ground faces for even cylinder wall contact
• Spring steel construction that retains tension through heat cycles
• Manufacturer part number 2933TD for straightforward lookup

On-The-Job Use

• Top end rebuilds on single cylinder two stroke engines
• Ring replacement during a piston change
• Compression recovery after a cylinder hone
• Routine service on racing and trail bikes

Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my engine? A: Match the 74.50mm bore and the 2933TD part number against your current piston and cylinder before ordering, since ring dimensions must align with the piston groove.

Q: Do I need to gap the rings after installation? A: Many rebuilders check end gap with a feeler gauge and file as needed, so measure against your engine's service spec before final assembly.

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