COMP Cams developed these hardened-steel ID spring locators specifically for LS applications to better handle modern spring pressures and high RPM. The locator uses an inboard shoulder to position and hold the spring while protecting the head and shim. The 4873 configuration lists a 1.300" OD and a 0.520" ID, offering a precise option for COMP-compatible LS spring setups.
