I-Beam “Heavy Duty” Series De-Stroke Connecting Rods

Designed for Watercraft Sea Doo 1630 XRT / GTX / XRP, these connecting rods are perfect for high horsepower and boost applications. Constructed from 4340 high tensile steel, they offer extreme durability and performance.

Features

• AMPCO 18 bushings for excellent wear and fatigue resistance, featuring a radial groove for oil reservoir.
• Shot peened to relieve stress and multi-stage heat treated for increased rigidity.
• Precision manufacturing ensures perfect fitment and optimized oil clearances.
• Includes 3/8 ARP 2000 cap fasteners rated at 220,000 psi, with an optional upgrade to ARP L19 material at 260,000 psi.

Additional Machining Processes

• Dowel sleeves for perfect fit and accurate re-assembling.
• Lipped cap relief for improved big-end integrity in extreme applications.
• Grooves in thrust face for weight reduction.

Technical Features
