★ This piston ring set is essential for a correct engine rebuild where the block has been bored 0.010". To be used exclusively with matching oversize pistons.

Application

For use in engine rebuilds where cylinders have been bored 0.010" to remove wear. Fits vehicles listed in the product category, equipped with L-134 Go Devil (flathead) or F-134 Hurricane (F-head) engines. Requires professional boring of the cylinder block and oversize pistons of matching dimension.

Installation notes

CRITICAL: These rings may ONLY be used with 0.010" oversize pistons in a 0.010" bored cylinder block. Use of oversize rings on standard pistons will cause engine damage. Check ring end gap per cylinder according to manufacturer specifications. Remove cylinder ridge before installation.

Compatibility

Exclusively for engines with 0.010" bored cylinder block. NOT compatible with standard cylinders or standard pistons. For greater wear (exceeding 0.010"), further boring to 0.020", 0.030" or 0.040" is necessary with matching piston and ring set.

Historical context

Oversize piston rings were already recognised practice during WWII for field rebuilds of engines with limited wear. The 134ci engines in military Jeeps were frequently overhauled in this manner to keep vehicles operational.
