10-01-11   Roller-Wave Pistons  are now only available in engines built here at ENDYN or with cylinder head packages. No exceptions. 

 

Important Notes

Use of these pistons requires cylinder clearances recommended in specification sheet that accompanies pistons. Cylinder walls must be properly honed for ring seating.
All B Series pistons in bore diameters larger than 82.0mm require the use of aftermarket sleeves with the exception of B20's which can use bore diameters as large as 85.0mm with careful tuning.
