Key Features

Skunk2 Racing Alpha Series Connecting Rods offer a combination of advanced materials and meticulous engineering to deliver superior performance and reliability. Key features include:

• Manufactured from high-strength forged steel for maximum durability and fatigue resistance
• Optimized rod geometry to reduce reciprocating mass and improve engine response
• Precision CNC machining for tight tolerances and perfect fitment
• Shot-peened surfaces to enhance fatigue strength and extend service life
• Fully balanced to ensure smooth engine operation at high RPMs
• Compatible with factory pistons and bearings for straightforward installation
• Designed specifically for the B58 engine platform to ensure ideal performance characteristics
• Finished with a protective coating to resist corrosion and wear

Construction & Design

The Alpha Series connecting rods are forged from premium-grade steel alloys, chosen for their exceptional strength-to-weight ratio and resistance to deformation under extreme loads. The forging process aligns the metal grain structure, resulting in rods that are significantly stronger than cast or billet alternatives. Each rod undergoes CNC machining to achieve precise dimensions and surface finishes, ensuring optimal bearing clearance and alignment.

Skunk2 Racing incorporates shot-peening treatment to induce compressive stresses on the rod surface, which greatly improves fatigue resistance and durability during high-stress engine operation. The rods are also balanced as a set to minimize vibrations and promote smooth engine performance, especially at elevated RPMs common in performance applications.

Installation & Fitment

These connecting rods are designed as direct replacements for the stock rods in the 2020–2026 Toyota GR Supra with the B58 engine, requiring no modifications to the engine block or other internal components. Installation should be performed by a qualified technician with experience in engine assembly to ensure proper torque specifications and clearances are met. Using these rods in conjunction with other performance upgrades can help maximize the potential of your Supra’s powertrain while maintaining reliability.
