Eagle CRS5236N3D Forged 4340 H-Beam Connecting Rods for 1985-1994 Nissan CA18DE

Vehicle Fitment

• 1985-1994 Nissan 200SX / Silvia / 180SX / Pulsar / Bluebird with CA18DE or CA18DET engine (I4, DOHC, 16-valve, Turbo where applicable)

Fitment Notes

• Designed for engines using **CA18DE** or **CA18DET**; not compatible with engines outside this family (e.g., SR20, RB, KA etc.)
• Full-floating piston pin required (rod is bushed for full-floating pin); ensure matching pistons for correct pin fitment
• Intended for performance, street, and competition builds; ensure block dimensions (housing bore, journal size) match standard CA18 specs

Features

• Forged 4340 steel construction for high strength and fatigue resistance
• H-beam profile to improve rigidity under high RPM and boost load
• Shot-peened and machined surfaces to reduce stress risers
• Weight-matched set to tighter tolerances for smooth operation
• Bushed for full-floating piston pin design to allow pin rotation and reduce wear
• Equipped with ARP 2000 bolts for secure rod cap fastening under high loads
• High-precision sizing: exact center-to-center length, journal/bolt/bore dimensions
• Recommended for competition or high-output CA18 builds; suitable for high boost or high RPM use

Specifications

• Material: Forged 4340 steel
• Center-to-Center Length: 5.236 in (≈ 133 mm)

Product Description

The Eagle CRS5236N3D is a high-performance set of connecting rods engineered for the CA18 family of Nissan engines (both CA18DE naturally aspirated and CA18DET turbocharged) used in various models between 1985 and 1994. These rods are constructed from forged 4340 steel in an H-beam design to deliver excellent strength, stiffness, and durability especially under increased power or elevated RPM. The rod set is weight-matched, shot-peened, and precisely machined to maintain balance, reduce vibration, and ensure reliable performance in aggressive builds.

Ideal for those modifying or rebuilding CA18 engines for racing, drifting, or high performance street use, these rods support full-floating piston pin setups and use ARP 2000 fasteners for superior bolt retention. To ensure fit and function, it is important to verify standard CA18 engine dimensions (housing bore, pin and journal sizes). Fitment is confirmed for years 1985-1994 CA18DE/CA18DET units. Use of correct pistons and compatible hardware is required for proper installation.
