Fitment-
Our silver stripe LS1 retainers will produce around .025" more installed height than std beehive retainers.
These are normally used for heads which have a thick aftermarket spring base/ locator.
GM's stock spring base is normally around .035" thick, many aftermarket locators are closer to .060" which can create .025" less height than required; this retainer will help correct this problem.
Also used to reduce seat pressure on high output beehive springs.
A hard to find item!
