SDR303008 Raceshop ID Style Spring Locator for LS and GEN5 LT - Single Piece - 1.309" OD & 0.080" Thick

Designed by the Raceshop for our own NHRA Stock Eliminator COPO Camaro that competes in Super Stock and Stock Eliminator with a GEN5 LT1 327ci PFI engine. Machined from 4140 steel, heat treated and made to our specifications. The LT1 and LT4 cylinder heads present a unique challenge for valve spring upgrades since the intake and exhaust have different installed heights based on the OEM valve design. These spring seat ID locators were originally designed to fit PSI Valve Spring DR427RML, PAC Springs 1237X and 1238X. Can also be used in other applications where the ID and OD of the spring will work with this spring seat locator dimensions as indicated in the chart. Available in both 0.100" and 0.080" thickness, in sets of 8-pcs or as single items for purchase.
