Application specific caps

  • NOTE1: Requires slight pan clearancing in some areas.
  • NOTE2: This high-performance item is not eligible for any further discounts or promotional pricing.

New main caps from Milodon are a must-have for any serious performance engine. These caps are CNC-machined from a high-strength combination of ductile metals and hardened to the proper levels which allow increased shock loads to the crankshaft and bearings. A minimal amount of drilling and machining is required to install these caps, but detailed instructions and the necessary bolts, washers and drill bushings are included for a hassle-free experience.
