In out quest for continually pushing the platform, we found ourselves at the point where even with our upgraded springs, we were fighting valve float at high boost and lift levels. After researching the issue, we found that the reused stock retainer is a significant portion of the valve/retainer/keeper assembly's mass. As ZZP does, we immediately began working on the solution.
These Titanium retainers are made to directly replace the stock retainers on our upgraded 1.4 valve springs, and reduce reciprocating mass by as much as 17%! This results in a significant improvement in valvetrain stability and a much larger window before valve float occurs, matching perfectly with our camshaft package.
Note: Slight change in spring installed height vs stock; NOT guaranteed to work with any other manufacturer's springs.
