Eagle CRS5984T3D 4340 H-Beam Connecting Rods Toyota 7M-GTE 5.984" Set of 6

Vehicle Fitment

• Universal - Fits Toyota 7M-GTE and 7M-GE inline-6 engines using a 5.984" center-to-center connecting rod, 2.047" rod journal, 0.866" wrist pin, and 2.167" housing bore
• Common vehicle application: 1986-1992 Toyota Supra (MA70 chassis, 7M-GTE Turbocharged and 7M-GE Naturally Aspirated)

Fitment Notes

• This is a universal connecting rod set - no specific vehicle trim or configuration fitment is assigned; builder must verify engine code, piston pin diameter, and bearing compatibility before installation
• Sold as a set of 6 rods - required for a complete inline-6 engine build; the Toyota 7M-GTE and 7M-GE use six cylinders
• Pin size: 0.866" - confirm your pistons use the 0.866" wrist pin before ordering
• Bushed for a full-floating piston pin - wrist pin is not press-fit; snap rings (not included) are required to retain the pin in the piston
• Rod bolt torque specification: 43 ft-lbs using ARP Moly Lube ONLY - do not substitute any other lubricant on ARP 2000 rod bolts
• Sold as a weight-matched set of 6 rods - all 6 rods are matched to within ±1g for balanced rotating assembly dynamics
• Not for use in pollution-controlled vehicles; recommended for competition use

Features

• Forged 4340 steel - certified SAE 4340 chromium-molybdenum-nickel alloy steel, vacuum-degassed for reduced internal porosity and consistent material properties throughout the rod; Eagle sources 4340 with a tighter alloy content specification than the AISI/SAE minimum, using a proprietary material mix that improves fatigue life and tensile strength for high-boost, high-RPM 7M-GTE competition builds
• H-Beam cross-section - provides an optimal strength-to-weight ratio for the 7M-GTE application, with 615g typical weight per rod achieving meaningfully less rotating mass than the factory 7M-GTE rods while delivering significantly superior fatigue life under sustained boost and high-RPM competition use
• Two-piece forging process - rod body and cap are forged separately, allowing grain orientation in each piece to be optimized for its specific load direction; the cap is forged with grain perpendicular to load forces for maximum cap strength, and precision cap alignment sleeves positively index the cap during assembly for accurate housing bore geometry and consistent clamping force
• Multi-stage heat treatment - stress relief and tempering after forging for uniform internal material properties and improved fatigue life
• X-rayed, sonic-tested, and magnafluxed - full non-destructive inspection of every Eagle ESP H-Beam rod to verify structural integrity before shipping
• 100% machined and shot-peened - all critical surfaces are fully machined to Eagle's dimensional tolerances, then shot-peened to relieve surface tensile stress and improve fatigue resistance
• Precision cap alignment sleeves - positively locate the cap on the rod body during assembly for accurate housing bore geometry and consistent big-end bearing clearance across all six rods
• 3/8" ARP 2000 12-point rod bolts - rated at 230,000 psi tensile strength, providing substantially stronger fastener engagement than standard 8740 bolts; 12-point head style allows accurate torque application in the inline-6 engine packaging environment
• Silicon bronze small-end bushing for full-floating 0.866" wrist pin retention
• Typical weight: 615g per rod; weight-matched to ±1g within the set of 6

Product Description

The Eagle CRS5984T3D is a weight-matched set of six forged 4340 steel H-beam connecting rods for the Toyota 7M-GTE and 7M-GE inline-6 engine, covering the 1986-1992 Toyota Supra MA70 platform. The set of six is the correct quantity for a complete inline-6 bottom end build. With a 5.984" center-to-center length, 2.047" rod journal, and 0.866" wrist pin, these rods are dimensionally correct for the 7M-GTE's crankshaft and piston specifications.

Each rod is forged from Eagle's certified vacuum-degassed 4340 chromium-molybdenum-nickel alloy steel through a two-piece forging process that separately forges the rod body and cap for optimized grain orientation in each section. Precision cap alignment sleeves locate the cap correctly at assembly for accurate housing bore sizing and consistent bearing clearance across all six positions. After forging, every rod undergoes multi-stage heat treatment, X-ray, sonic testing, magnaflux inspection, 100% machining, and shot peening. At 615g typical weight per rod, these H-beams are lighter than the factory 7M-GTE connecting rods while delivering substantially superior fatigue life and structural integrity for high-boost, high-RPM competition applications.

The set ships with 3/8" ARP 2000 12-point rod bolts rated at 230,000 psi tensile strength. The 12-point head design allows accurate torque application in the tight packaging of the inline-6 cylinder bank. All rod bolts must be torqued to 43 ft-lbs using ARP Moly Lube only - no substitute lubricant should be used. The small end is bushed for a full-floating 0.866" wrist pin. All six rods in the set are weight-matched to within ±1g. Not for use in pollution-controlled vehicles.
