These extra-long CSP Products rocker studs are made to be used with shimmed blocks on Type-1 and WBX engines. They are on par with stock studs as far as quality, and are made in Germany of course!

When setting the rocker geometry and shimming the blocks, you usually can't use the stock studs anymore as they are too short. Thanks to a longer fitting surface (+6.8 mm) and a longer overall length (+6.3 mm), the CSP Products studs solve all your problems. The Grade 10.9 studs feature rolled threads and fit under stock valve covers.
