Our P/N 135-ST Steel Retainer weighs the same as the Stock LS-1 "Stamped" Retainer but is superior in strength. It is machined from 4130 Chromemoly Steel & Heat Treated for Maximum "Pull-Thru" Strength. The combination of the 135-ST steel retainer and our "Machined" VL-500 Bead Locks yields a more precise, consistent installed height and gives added insurance in your LS-1 Engine with more aggressive hydraulic roller cam profiles at higher RPM. This combination can be used with stock LS-1 "B-HIVE" springs as well.
