Spacer kit re-designed in 2005 for correcting rocker alignment. This kit has been produced to help rocker pad and valve stem alignment plus reducing friction. The standard springs can be replaced with this special kit of three (3) spacers (two small and one large) plus a correct amount of shims. This superior kit, replaced the old 3 spacer type which could never give accurate alignment owing to the variations in A series cylinder heads.
Shims (AEG168 and AEG169) are also available separately.
