RBS has found this to be the simplest and most convenient way to change valve springs on the bench with fuel or alch. Hemi heads. Slip the tool over the face of the valve and over the top of the valve spring, pull the trigger to compress and pull the other trigger to release.
Spring compressor body is made from durable billet alum. that has been black anodized for corrosion protection and makes the tool manageable to handle.
Please specify 1.610" Dual or 1.760" Triple dia. valve spring when ordering.
