For years the British motorcycle industry has been plagued with very low quality valve springs, especially for A50 & A65 unit twins... Luckily CBS was able to get Kibblewhite to make a quality and comprehensive spring kit for our unit twins
This spring kit we are offering is new for 2023 - "lightweight" kit comes included with everything as pictured from (8) keepers, (4) top retainers, (4) bottom base washers & (8) springs
This kit is perfect for street applications and mild racing applications paired with standard / mild lift cams... - made proud in the USA. Works will all BSA unit twins including the following models: Royal Star, Lightning, Firebird, Spitfire, Spitfire, etc from 1962-1972.

Nice spring kit,
Significantly superior quality valve train components. This spring set helped resolve my coil binding issues, reduces weight from the valve train and makes me smile every time the rocker cover comes off
I highly recommend these springs. I had the exact problem described in the tech blog resulting in bent pushrods and a broken rocker. These springs resolved those issues.
