ARP 204-6004 Porsche 911 RSR Titanium Ti Connecting Rod Bolt Kit

Unquestionably the most important fasteners in any engine are the connecting rod bolts, as they hold the key to the entire rotating assembly. A broken bolt will lead to catastrophic engine failure. As you can imagine, the most critical joint is where the connecting rod halves mate. The rod bolts must support the primary tension loads caused by each rotation (or cycle) of the crankshaft. When the crank rotates, the big end of the connecting rod essentially becomes oval-shaped and the rod bolts bend. As the crankshaft continues to rotate, the rod becomes round again. With alternating tension loads and cyclic bending of the bolts, it is very important to install fasteners that are able to exert a clamping force greater than the load imposed upon the joint (tension).

In addition to utilizing a rod bolt with sufficient strength to withstand the tremendous cyclical strains placed upon it, it is absolutely imperative that the bolts be properly tightened. The preferred method of monitoring the correct amount of tension is through use of a stretch gauge. This is far more accurate than using a torque wrench. Moreover, through subsequently checking the rod bolts length at teardowns, it is possible to determine if it has been stressed beyond safe limits and must be replaced.

For the most severe applications, in conjunction with aftermarket I-beam rods, ARP has developed the "Pro" Series Wave-Loc bolts. These ultra heavy-duty rod bolts are made from a special material designed ARP2000 and feature a black oxide finish. It has approximately 200% the fatigue life of 8740 chrome moly steel and has a tensile strength of 220,000 psi, and is capable of more than 12,000 lbs clamping force.

Don't risk a failure by reusing weak factory rod bolts. Upgrade to ARPs and never worry about your Porsche connecting rod bolts ever again!

Installation Method for Porsche Rod Bolt Kit


Part Number: 204-6004

Application: Porsche RSR Titanium Rod



  1. Please check the part-number(s) for your application against the part-number(s) listed on the instruction sheet.

  2. Make sure there is an adequate chamfer around the top of the connecting rod bolt hole to clear the radius under the head of the bolt.

  3. Press the bolts into the connecting rods and install the rod caps.

  4. Use ARP Ultra-Torque Fastener Assembly Lubricant to lubricate the threads of the bolt and the nut face. Then install the nuts onto the bolts and tighten them hand tight.

  5. ARP recommends using the STRETCH METHOD when tightening the bolts. Following the instructions for using a stretch gauge, stretch the bolts to .0095 - .0100.

  6. If you do not have a stretch gauge, torque the bolts to 50 ft-lbs using ARP Ultra-Torque Fastener Assembly Lubricant.

  7. The connecting rods should always be re-sized after new rod bolts are installed.

  8. A log should be kept on the original non-torqued length of each bolt. Bolts that have any permanent deformation or have increased in non-torqued length by more than .001 in. should be replaced.
