When it comes to building your FA20 motor, upgraded case studs are necessary to keep the cylinder block firmly seated together. Case studs are the boxer motor equivalent to main studs on a regular motor. The Dynosty Case Stud kit allows for maximum case clamping to ensure the FA20 block is securely fastened for increased power.
Kit includes: Set of FA20 case studs, washers and nuts. (Engine pictured not included)
