Skunk2 Racing Alpha Series Connecting Rods

2013–2020 Scion FR-S, Subaru BRZ & 2017–2020 Toyota 86

306-12-1010

Overview:

The Skunk2 Racing Alpha Series Connecting Rods are engineered for enthusiasts and racers seeking exceptional strength and reliability for their Scion FR-S, Subaru BRZ, and Toyota 86 engines. Designed to handle high horsepower builds up to 900 hp, these rods provide a critical upgrade for those pushing their naturally aspirated or forced induction setups to the limit. With a focus on durability and precision, the Alpha Series rods ensure consistent performance under extreme conditions, making them an ideal choice for track, street, and competition applications.

Whether you are upgrading your engine for increased power or replacing factory rods for enhanced reliability, the Alpha Series offers a perfect balance of strength and weight, helping to improve engine response and longevity.

Key Features:

Skunk2 Racing’s Alpha Series Connecting Rods incorporate advanced engineering and manufacturing techniques to deliver superior performance and durability. Key features include:

  • Forged from premium 4340 chromoly steel for outstanding strength-to-weight ratio
  • H-beam design optimized through nearly three years of development and Finite Element Analysis (FEA) for maximum stress distribution
  • Capable of handling over 900 horsepower, suitable for high-performance builds
  • Two-piece forging construction for optimal grain orientation along the rod cap, enhancing strength and fatigue resistance
  • Dual offset oil passages at the pin ends for improved lubrication and cooling of the wrist pin throughout the engine cycle
  • Comprehensive heat-treating, tempering, and shot-peening processes to ensure consistent material integrity
  • Magna-flux inspection to verify structural integrity and adherence to strict quality standards
  • Precision-machined fit between rod cap and beam without brittle materials, ensuring durability and reliability
  • Includes high-strength 3/8 ARP2000 bolts and assembly lube for secure installation

Construction & Design:

The Alpha Series Connecting Rods are crafted from select 4340 chromoly steel, known for its exceptional tensile strength and toughness. Skunk2’s close collaboration with their foundry and rigorous material testing ensures that only the highest quality steel is used. The rods undergo a meticulous manufacturing process including heat-treating, tempering, and shot-peening to enhance fatigue resistance and durability.

The H-beam design was developed using Finite Element Analysis to identify and reinforce high-stress areas, resulting in a rod that distributes load evenly and reduces wear. The two-piece forging method aligns the metal grain along the rod cap in the direction of stress, significantly increasing strength compared to traditional one-piece rods. Additionally, the dual offset oil passages provide superior lubrication and cooling, reducing friction and extending rod life under demanding conditions.

Installation & Fitment:

These connecting rods are designed as direct replacements for the factory rods in 2013–2020 Scion FR-S, Subaru BRZ, and 2017–2020 Toyota 86 models. Installation requires standard engine disassembly and reassembly procedures, and it is recommended to have the work performed by a professional engine builder or experienced technician. The rods come with ARP2000 bolts and assembly lube to ensure proper torque and secure fastening during installation.

No modifications to the engine block or crankshaft are necessary, making these rods a straightforward upgrade for high-performance engine builds.

What's Included:

  • Set of 4 Skunk2 Alpha Series Connecting Rods (129.38mm length, 502 grams each)
  • 3/8 ARP2000 high-strength rod bolts
  • Assembly lube for installation

Ideal For:

The Alpha Series Connecting Rods are ideal for enthusiasts and professional builders upgrading their Scion FR-S, Subaru BRZ, or Toyota 86 engines for high horsepower applications. Whether you are building a turbocharged, supercharged, or naturally aspirated engine, these rods provide the strength and reliability needed to handle aggressive tuning and track use. They are also well-suited for motorsport disciplines such as road racing, time attack, and drift where engine durability is critical.
