Custom manufactured ARP studs designed to not interfere with the valve cover on any CRD.  These studs are not undercut and are stronger than the alternative stud version.

Set of 18 ARP head studs, nuts and washers for the Jeep Liberty CRD.

This kit includes:

  • 18 x ARP2000 studs that can fully bottom inside the block for easier installation, especially important with the higher torque inner bolts.
  • ARP installation grease, required for proper torque.

These ARP studs are made with ARP's newest proprietary metal, ARP2000, that has a nearly 20,000 psi material strength.  Threads are cold rolled, not cut, to avoid damage to stud integrity.  

In addition to being a much stronger material, using these studs has two other disctinct advantages.  The primary advantage is how torque is applied.  When torqing a bolt, there is both squeezing pressure and friction load from the threads turning inside the block.  By using an ARP stud, the torque applied to the nut is fully utilized in squeezing the cylinder head and block together, meaning a more accurate torque and less stress on the block threads.  Secondly, the washer has a larger squeezing surface than the stock head bolt - spreading the squeezing force out over a larger area limits the chances of distorting the softer aluminum head.

Includes installation instructions with torque values.
