  • Shim under bucket valve lash caps

    Wondering for those who run shim under bucket if there is a maximum thickness for the valve lash cap. I am swapping cams with a smaller base circle while keeping the same valve length and need a thicker valve lash cap (range 4.4-4.65mm). Before they were 1mm shorter.

    Will going thicker increase the risk of the lash cap slipping out or rocking out?

    I am currently running the Supertech shim-unders....3.5mm is the thickest shim they offer. It is a bit of a different design...just uses a small metal disc that fits inside a recess in the bucket.

    My previous setup I was using Arrow buckets along with lash "caps" on the valve stem. I'm not sure how thick those were available.
