1. Which Subaru models and engines do these H-beam connecting rods fit?
They are engineered for Subaru EJ-series 4-cylinder engines including EJ20, EJ22 and EJ25 found in various Impreza (WRX/STi), Legacy, Forester and Outback models (examples: GC8, GDB, EJ205/EJ207/EJ255/EJ257 applications). Always verify fitment for your specific year and engine code before purchase.
2. What material and manufacturing processes are used?
Forged from SAE 4340 (EN24) chrome-moly steel, multi-stage heat-treated, shot-peened, CNC machined, magnaflux/MP tested and 100% X-rayed/sonic tested for material integrity and fatigue resistance.
3. What type of fasteners are included and can they be upgraded?
Sets include genuine 3/8" ARP 2000 bolts (rated ~220,000 psi). An optional upgrade to ARP L19 bolts (rated ~260,000 psi) is available for an extra cost.
4. Are these rods sold as a complete set and do they include bolts?
Yes — they are supplied as a complete set sized for Subaru 4-cylinder engines and include ARP 2000 bolts by default. Boltless variants are also offered for customers who prefer to use their own fasteners.
5. What are the key dimensions and tolerances?
Center-to-center length: 130.5 mm (5.137"). Big end diameter: 55.0 mm. Small end diameter: 23.0 mm. Big and small end widths: 21.38 mm. Big end bores are honed to approximately +/-0.0004" and all bores are finished to +/-0.01 mm.
6. What is the weight matching tolerance for the set?
Sets are balanced and weight-matched to within +/- 1 gram per rod to ensure consistent rotating assembly balance.
7. What horsepower capacity do these rods support?
Specification lists a nominal rating of 200 HP per rod. For high-horsepower or heavily modified engines you should consider bolt upgrades (ARP L19) and consult a professional engine builder.
8. What quality checks and testing are performed?
Each rod undergoes magnetic particle (magnaflux) inspection, shot peening, 100% X-ray and sonic testing, plus dimensional checks and laser-etch marking for traceability.
9. Is there a warranty and what does it cover?
A 2-year warranty against manufacturing defects is provided. It typically does not cover damage from improper installation, engine failure due to other components, racing abuse beyond intended use, or normal wear; follow installation instructions and retain proof of purchase.
10. Do these rods include wrist pin bushings?
Yes — bronze wrist pin bushings are fitted to increase wear resistance and extend wrist pin life.
11. Can these rods be used for turbocharged/race engines?
Yes — the H-beam 4340 forged design, heat treatment and testing make them suitable for demanding and turbocharged applications, but confirm overall rotating assembly strength and consider bolt upgrades for very high horsepower builds.
12. Do I need to perform additional machining or fitment checks before installation?
Yes. Although bores are precision-honed, you should verify big-end bore clearances, piston-to-wall and piston-pin clearances, and rod-to-crank journal clearances. A machine shop or experienced engine builder should perform final clearancing and torque procedures.
13. What are the recommended installation practices for rod bolts?
Follow ARP's torque and/or torque-plus-angle specifications for the supplied bolts. Replace rod bolts if they are reused beyond recommended service life, and always use proper assembly lube and a calibrated torque wrench or angle gauge.
14. Are there cosmetic or customization options?
Yes — rods feature a laser-etched maXpeedingrods logo for authenticity. Non-logo products and private/custom logo options are available on request. Titanium-plated upgrade models are also offered.
15. Should I have balancing done after installation?
Yes — while the rods are matched to +/-1 g, a complete rotating assembly balance (including pistons, wrist pins, rings and rods) is recommended when building a high-performance or race engine to minimize vibrations and maximize reliability.
