Overview:

The Brian Crower Connecting Rods are precision-engineered performance components designed specifically for the Subaru BRZ (2013–2017) and Toyota 86 (2017) equipped with the 4UGSE engine. Built to replace the factory rods, these connecting rods provide enhanced strength and durability for enthusiasts seeking to improve engine reliability under increased power and high RPM conditions. Ideal for sportsman-level builds, they offer a reliable upgrade for drivers pushing their naturally aspirated or mildly boosted engines beyond stock limits.

These rods come equipped with ARP2000 fasteners, ensuring secure and consistent clamping force to withstand the rigors of spirited driving and track use. Whether you are upgrading for improved engine longevity or preparing for moderate performance enhancements, Brian Crower connecting rods deliver a solid foundation for your build.

Key Features:

Brian Crower connecting rods combine advanced engineering with quality materials to meet the demands of performance enthusiasts. Key features include:

• Length of 5.094 inches, optimized for the Subaru BRZ and Toyota 86 4UGSE engine configuration
• Manufactured from high-strength forged steel for superior durability and fatigue resistance
• Equipped with ARP2000 fasteners for reliable bolt stretch control and consistent clamping force
• Precision machined to exacting tolerances for perfect fitment and balanced performance
• Designed to handle increased horsepower and RPM safely beyond stock limits
• Ideal for naturally aspirated, turbocharged, or supercharged applications within sportsman-level builds
• Direct bolt-in replacement for factory rods with no modifications required

Construction & Design:

Brian Crower connecting rods are crafted from premium forged steel, providing an excellent strength-to-weight ratio essential for high-performance applications. The forging process enhances the grain structure of the steel, resulting in rods that resist bending, stretching, and fatigue under extreme engine loads. Each rod undergoes precision CNC machining to ensure exact dimensions and surface finishes, promoting optimal bearing fit and smooth piston movement.

The rods feature a fully machined beam design that balances rigidity with weight savings, contributing to improved engine response and durability. The inclusion of ARP2000 fasteners, known for their high tensile strength and reliability, further secures the rod assembly, reducing the risk of fastener failure during high-stress operation.

Installation & Fitment:

These connecting rods are designed as direct replacements for the Subaru BRZ (2013–2017) and Toyota 86 (2017) models equipped with the 4UGSE engine. Installation requires standard engine disassembly procedures and should be performed by a qualified technician or experienced enthusiast. No modifications to the engine block or crankshaft are necessary, ensuring a straightforward upgrade path.

Proper installation includes precise torqueing of the ARP2000 fasteners to manufacturer specifications and verification of bearing clearances. This ensures optimal performance and longevity of the connecting rods within the engine assembly.

What's Included:

• Set of Brian Crower forged connecting rods (quantity as required for engine)
• ARP2000 high-strength rod bolts pre-installed
• Installation instructions and torque specifications

Ideal For:

These connecting rods are ideal for Subaru BRZ and Toyota 86 owners who are upgrading their engines for enhanced durability and performance.
