The wrist pin end of the rod features a wear resistant bushing material made from AMPCO 45 - a high strength alloy with mechanical properties beyond that of commercial nickel-aluminum bronzes. Wear reduction is further enhanced via a pin lubrication access point at the top of the rod, feed by the engine's oil squirters. For further weight reduction and drop in rod compatibility with OEM and APR pistons, the wrist pin end is tapered. When modifying an engine for strength and longevity, quality is of the utmost importance. APR's Engineering teams have ensured each rod is created with absolute quality and control in mind each step of the way. Tolerances are kept to OEM specs and the rods are balanced to within +/- 1 gram. Furthermore the rods undergo rigorous tests to backup the entire manufacturing process. Rockwell testing provides a method for testing hardness while Magnaflux or Magnetic Particle Inspection, offers a method for detecting interruptions in the physical continuity of the casting. The result is a product you can trust.

Mahle Motorsport VP2 Rod Bearings

When upgrading connecting rods, it's necessary to replace the existing connecting rod bearings. APR recommends using Mahle Motorsport VP2 rod bearings for their superior strength and wear resistance properties and attention to detail over the similarly priced OEM bearings. Each bearing is capable of taking abuse in the magnitude of 14,500 psi while still offering superior conformability and fatigue resistance not commonly seen elsewhere in the market. This is partially due to the bearing's high-grade hardened steel backing with bronze substrate and lead/indium overlay. Laser etched part numbers rather than typical stampings aid in significantly improved heat transfer and prevention of shell distortion. Formula 1 standards dictate extremely high tolerances, while Mahle's attention to detail and chose of fine materials ensure worry free operation.

Install Kit Includes

Upgrading connection rods requires disassembly of the engine, including several items designed for one time use only. Upon reassembly, new gaskets, stretch bolts, sealant and such are necessary to ensure years of reliable operation.

- OEM Timing Cover Gasket

- OEM Head Gasket

- OEM Valve Cover Gasket

- OEM Exhaust Manifold Gasket

- OEM Intake Manifold Gasket

- OEM Camshaft Seals

- OEM Gasket Sealant

- OEM Valve Cover Bolts

- ARP Head Stud Kit

- OEM Camshaft Plug

- OEM Victor Reinze Sealant

Mahle Motorsport German Tool Steel Wrist Pins

For ultimate strength and reliability, APR recommends upgrading to Mahle's German tool steel wrist pins while upgrading connecting rods. If ordering APR's Pistons, wrist pins are included.
