Description

ARC 6252 +0.040" Billet Connecting Rod for Predator 212 (Hemi & Non-Hemi)


Upgrade your engine with the ARC 6252 +.040" Long Billet Connecting Rod, engineered for Predator 212cc engines used in kart racing, mini bikes, and high-performance small engine builds. Manufactured by ARC Racing, this precision rod delivers superior strength, improved geometry, and increased compression potential for serious racers.

Machined from 7075-T651 aircraft-grade aluminum, the ARC 6252 offers an exceptional strength-to-weight ratio, making it ideal for high-RPM racing applications where durability and reliability are critical.


Performance Benefits

  • +0.040" Longer Rod Design
    Increases compression and optimizes piston-to-deck height—especially effective in Non-Hemi Predator 212 builds.
  • Improved Engine Efficiency
    Optimized rod length enhances combustion efficiency and can improve throttle response and torque output.
  • High-RPM Strength & Reliability
    Billet 7075-T651 aluminum construction withstands the stress of aggressive kart racing and mini bike performance setups.
  • Advanced Oiling System
    ARC’s forced oiling scoop dipper improves lubrication to the rod journal, reducing wear and extending engine life.
  • Precision Bearing Inserts
    Includes ARC’s custom bearing inserts for consistent oil clearance and long-term durability.


Engine Build Notes (Important)

  • Non-Hemi Predator 212 (Most Common Use):
    Best paired with a 70mm flat top piston to achieve near zero deck height and increased compression—ideal for racing applications.
  • Hemi Predator 212:
    Requires a shorter compression height piston and may need piston machining to achieve proper deck height.

Always verify piston compatibility and deck clearance during assembly.


Key Specifications

  • Rod Length: 3.348" center-to-center (+.040")
  • Rod Journal Diameter: 1.188"
  • Wrist Pin Size: .709"
  • Material: 7075-T651 billet aluminum

Built for Kart Racing & Mini Bike Performance

The ARC 6252 billet rod is a critical upgrade for builders looking to push the limits of the Predator 212 platform. Whether you're dialing in a kart racing engine for maximum acceleration or building a mini bike for high-speed performance, this rod provides the strength, geometry, and reliability needed to compete.

FAQ

Q: What is the benefit of a +0.040" longer rod in a Predator 212?
A: A +.040" longer rod increases piston height in the cylinder, which can improve compression and help achieve near zero deck height for better combustion efficiency.


Q: Is the ARC 6252 rod compatible with both Hemi and Non-Hemi engines?
A: Yes, it fits both Predator 212 Hemi and Non-Hemi engines, but it is most commonly used in Non-Hemi builds for optimal compression setups.


Q: What piston should I use with this rod?
A: Non-Hemi engines typically use a 70mm flat top piston. Hemi engines require a shorter compression height piston and may need machining for proper deck clearance.


Q: Do I need to modify anything to install this rod?
A: Basic engine assembly knowledge is required. Depending on your setup, you may need to verify piston-to-deck height and clearance to ensure proper fitment.


Q: Are bearing inserts included with the ARC 6252 rod?
A: Yes, it comes with ARC’s precision bearing inserts designed for proper oil clearance and durability.


Q: Is this rod safe for high RPM racing?
A: Yes. It is made from 7075-T651 billet aluminum and includes high-strength ARP rod bolts, making it ideal for high-performance kart racing and mini bike engines.


Q: What oil clearance should I run with this rod?
A: Recommended oil clearance is approximately .003"–.004" for optimal lubrication and reliability.


Q: What makes this rod better than a stock rod?
A: It offers significantly greater strength, improved oiling, better high-RPM durability, and the ability to optimize compression for racing applications.
