Installing a worn rocker box shaft will only make maters worse during your Triumph engine rebuild. A worn shaft can throw off timing and cause excessive valve chatter and wear.

Today we are offering you new English made Triumph rocker box spindle shafts manufactured by L.F. Harris. These rocker shafts are machined and ground to the correct O.D. The threaded ends are hardened.

We stock rocker box spindle shafts that come with an oil groove and some without an oil groove to fit various Triumph 350, 500, 650 and 750 twins including the pre-unit twins (3TA, 5TA, T100, 6T, T100, T120, T140, TR7, etc). Check your parts book to ensure the best fitment.
