*** IN STOCK SHPS TODAY *** For the racer that made the investment for an MTI valve spring compressor and has used it for years and now it seems to work not as well as you remember or has an annoying hissing air leak, RBS to the rescue with a full O-ring, trigger rebuild kit. For a little time and a small investment the racer can bring that mighty tool back to its former glory and again be the envy of the pits wit your air operated valve spring compressing tool.
