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 Toyota 4UGSE engine. These rods provide a critical upgrade for enthusiasts seeking enhanced engine durability and reliability under increased power and high RPM conditions. Crafted to withstand the rigors of spirited driving, track use, and moderate forced induction setups, these connecting rods offer a balance of strength and weight savings that help improve engine response and longevity.

Ideal for tuners and racers who demand consistent performance from their naturally aspirated or mildly boosted 2.0-liter boxer engines, Brian Crower connecting rods deliver the confidence needed to push the limits without compromising engine integrity.

Key Features:

Brian Crower connecting rods combine advanced materials and manufacturing techniques to ensure superior performance and durability. Key features include:

• 5.094-inch length optimized for the Toyota 4UGSE engine architecture
• H-Beam design for maximum strength-to-weight ratio and reduced flex under load
• Constructed from high-grade forged steel for exceptional toughness
• Equipped with ARP Custom Age 625+ bolts for enhanced clamping force and fatigue resistance
• Precision machined for exact fitment and balanced weight distribution
• Compatible with stock and upgraded pistons and crankshafts
• Designed to improve engine reliability during high RPM operation and increased power output
• Direct fit for Subaru BRZ (2013–2017) and Toyota 86 (2017) with no modifications required

Construction & Design:

Brian Crower connecting rods are forged from premium-grade steel, ensuring a robust yet lightweight component capable of handling the stresses of performance driving. The H-Beam configuration offers superior rigidity compared to traditional I-beam rods, reducing bending and twisting forces during combustion cycles. This design choice enhances durability while maintaining a competitive weight, which contributes to quicker engine response and reduced rotating mass.

The rods are finished with meticulous CNC machining to achieve tight tolerances and precise balancing. The use of ARP Custom Age 625+ fasteners further elevates the assembly’s strength, providing reliable clamping force that resists stretching and fatigue over time. This combination of materials and engineering results in a connecting rod set that meets the demands of both street performance and track applications.

Installation & Fitment:

These connecting rods are engineered as a direct replacement for the factory rods in Subaru BRZ models from 2013 through 2017 and the 2017 Toyota 86, ensuring straightforward installation without the need for custom modifications. Installation should be performed by a qualified engine builder or technician familiar with precision engine assembly to guarantee proper torque specifications and clearances.

Brian Crower rods maintain OEM dimensions, allowing compatibility with stock pistons and crankshaft setups. However, it is recommended to inspect and measure all related components during installation to ensure optimal engine performance and reliability.

What's Included:

• Set of four Brian Crower H-Beam connecting rods (5.094-inch length)
• ARP Custom Age 625+ connecting rod bolts
• Installation instructions and torque specifications
