These 122 mm H-beam rods are designed for Toyota 4A-FE engines and list fitment for Corolla (Seca/AE92), Celica, Carina, FX and MR2 models using the 4A-FE. Verify crank and piston pin dimensions on your engine before ordering.
Center-to-center length: 122 mm; big end diameter: 43 mm; small end diameter: 20 mm; big end width: 21.74 mm; small end width: 21.74 mm.
Forged 4340 aircraft chrome-moly steel H-beam connecting rods (racing quality).
The product includes a set of 4 connecting rods. They are balanced as a set to a tolerance of ±1 gram.
The rods include genuine 3/8" ARP 2000 bolts. An upgrade to ARP L19 bolts is available for an extra cost — contact the seller for pricing and options.
Recommended torque is 48 ft-lb (approximately 65 Nm) for the included bolts. Follow ARP and engine manufacturer installation procedures (lubrication, torque sequence, and re-torque if specified).
The listing specifies a power capability of 600 hp ~ 800 PS per set and a maximum engine speed of 9000 rpm. Use these values as guidance and consult a professional for high-boost or extreme builds.
That figure refers to the tensile strength rating of the fastener material (bolts) — approximately 220,000 to 230,000 psi — indicating high-strength ARP-grade fasteners are used or available.
The piston pin (wrist pin) hole tolerance is specified as ±0.004 mm (±4/1000 mm).
Yes, the product includes a 2-year warranty. Check seller terms for warranty coverage details and any exclusions (e.g., misuse or racing).
The reference/OEM number provided is CR-TOY-122-43.
They are forged 4340 H-beam rods rated for high horsepower (specified as 600 hp ~ 800 PS per set) and high RPMs, which makes them suitable for many high-performance and forced-induction applications. However, suitability depends on your specific build and tuning — consult an engine builder to confirm compatibility.
Some engines require small bearing clearancing or machining depending on crankshaft chamfers, bearing selection, and installation practices. Have a qualified machinist check big-end clearances, align hone if required, and verify fitment before final assembly.
