ARP 168-4201 Engine Head Stud Kit for Sea-Doo RXP-X 255

$165.10

$165.10

Fits Sea-Doo RXP-X 255 personal watercraft models.

High-performance personal watercraft engines demand superior clamping force to maintain head gasket integrity, especially under the increased cylinder pressures of a supercharged 255-series engine. This ARP (168-4201) Engine Head Stud Kit replaces the factory torque-to-yield bolts with high-strength studs that provide more consistent torque loading and prevent head lifting.

Each fastener is manufactured from premium 8740 chromoly steel and heat-treated to a 200,000 psi tensile strength rating. Unlike lesser fasteners, ARP threads are rolled after heat treatment, which provides significantly better fatigue resistance. This kit is essential for any performance build or engine rebuild where reliability is the priority.

  • Manufacturer Part Number: 168-4201
  • Material: 8740 Chromoly Steel
  • Tensile Strength: 200,000 psi
  • Thread Type: Precision J-form rolled threads
  • Includes: High-strength head studs, parallel-ground washers, 12-point nuts, and ARP Ultra-Torque fastener assembly lubricant
