ARP head stud kit designed specifically for Land Rover vehicles with Rover 3.9L 4.0L 4.6L V8 engines and 10 bolt cylinder heads including Range Rover Discovery and Defender models from 1989 to 2004.

  • Precision Threads: Rolled before heat treatment for maximum fatigue strength and consistent engagement in aluminum heads
  • Matched Hardware: Includes washers and twelve-point nuts for complete kit and simplified bolt-on assembly
  • Versatile Application: Handles stock rebuilt or modified engines in Land Rover V8 swaps or performance builds

Product Notes

  • Verify 10 bolt head configuration before purchase matches your engine
