Description

EC Pinnacle-Series 3.415" Forged Connecting Rod – Designed for Tillotson 236R Stroker Engines


Built for high-performance racing, the EC Pinnacle-Series Forged Connecting Rod (Part #8279) is engineered specifically for the Tillotson 236R Engine Kit. Precision-forged and CNC-machined to tight tolerances, this 3.415-inch rod delivers the strength, durability, and efficiency needed for today’s most demanding small-block stroker builds.


Perfect for turning Tillotson 225/72mm bore blocks into 236cc stroker engines, this rod is a vital upgrade for racers pushing their engines to higher RPM ranges without compromising reliability or performance.


Why Choose a Forged Connecting Rod?

Forged vs. Billet:
Unlike billet rods, which are cut from a solid piece of aluminum, forged rods are formed under extreme pressure, realigning the grain structure for superior density, strength, and ductility. This results in:

  • Greater fatigue resistance
  • Improved power-to-weight ratio
  • Reduced risk of failure under high RPM stress

The EC Pinnacle-Series forged rod is lighter and stronger than traditional billet designs, making it ideal for competitive karting and high-RPM mini bike racing applications.


Engineered for the EC Tillotson 236R Rotating Assembly

This connecting rod is designed to work seamlessly with EC's 72mm Tillotson piston and 58mm stroker crankshaft, turning your 225cc block into a high-output 236cc engine. It offers precise piston height control and optimized rod-stroke ratios for:

  • Increased compression
  • Improved top-end power
  • Smooth, efficient power delivery


Rod Specifications:

  • Material: Precision-Forged Aluminum Alloy
  • Rod Length (Center-to-Center): 3.415” / 86.75mm

FAQ

Q1: Will this rod work with the Predator 224 or Wildcat 223 engine?
A1: No, this rod is specifically designed for Tillotson 225/236R engine kits using the 58mm crankshaft and 72mm bore combination.


Q2: What piston and crankshaft is this rod designed to work with?
A2: It is designed to work with the Tillotson 72mm hypereutectic piston and a 58mm stroke crankshaft, converting a 225cc engine into a 236cc stroker.


Q3: Can I use this rod in a stock GX200 or Predator 212?
A3: No, this rod is too long for stock stroke and piston configurations. It is intended for stroker engines with modified stroke and bore dimensions.


Q4: What is the advantage of the 3.415" length over a 3.303" or 3.353" rod?
A4: The 3.415" rod length helps position the piston at optimal deck height in 236cc builds, maximizing compression and improving rod ratio for better high-RPM stability.
