No one makes the LT-5 rings.....Total Seal sent over a set

The top ring is .004 side clearance vs stock at .002-.003


How much backspace is too much?, these are .025 stock is .016

Thanks

 

End gap has a LOT of variables. The most significant being ring material and application. A steel ring needs a diff gap compared to a moly ring, a heavy nitrous application needs a different endgap than say a mild street motor, etc.

Backspace you typically want as tight as you can without binding up when at temperature...once again, ring material comes into play. A larger backspace can be useful with gas ported pistons for instance. .025 sounds on the large side. I'd get up with Total Seal, they should know more than anyone....
