CHECKING PISTON COMPRESSION RING GAPS
Created: September 21, 2010
The following chart shows the SAE recommended Automotive compression ring end gaps. These recommendations are followed for the majority of the ring line unless a certain application requires deviation from the chart.

When Omega quit making A-Series pistons, Mini Spares took it upon themselves to design and build a better Piston. Recruiting the AE Hepolite Group for their unquestionable and renowned design and manufacturing expertise, the goal was to produce the most robust piston possible given reasonable cost and weight limits. Applying current technological advances incorporating their very latest hi-spec AE109TF lightweight alloy and special double heat treatments, the result is an extremely durable piston that will withstand greater cylinder pressures at higher RPM than any other currently available.
Piston Fact File
Created: January 30, 2000
Over the years, there have probably been a dozen "stock" 1275 pistons. Currently, three different designs are available from AE/Hepolite as "stock" replacements. All have an 8.4cc dished top, but compression ratios are carried by changing pin height (Pin height is the distance from the top of the piston to the center of the wrist pin- see dimension "A" shown here).
