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 3 spacers (2 small and one large) plus a correct amount of shims. The shims (AEG168 & AEG169) are also available separately.

This new, far superior kit, replaced the old 3 spacer type which could never give accurate alignment owing to the variations in A series cylinder heads.

Designed for any of our roller tip rockers, forged hi-lift rockers and forged standard cooper S rockers on A series.
