Norton Commando, Atlas, 4340, H-Beam Steel Connecting Rods (pair)

MAP Cycle is proud to offer our 4340 H beam connecting rods. The exotic 4340 forged steel makes for a lifetime rod.

Fits:

• Norton Commando (all models 1967-77)
• Norton Atlas (1963-68)
• Norton G15
• Norton N15 (1967-68)
• Norton P11A/Ranger (1967-68)

Features:

• Sold in matched pairs - balanced to +/- 1 gram
• Unmatched quality - the best rods available anywhere for Triumph
• "Solid Works" designed and stress tested
• Machined from 4340 forging
• Shot peened for stress relief
• ARP2000 bolts (220,000 lb. tensile strength)
• Innovative machined piston oil squirting notches
• Double wrist pin oilers
• Unique reinforced small end critical areas without adding excess weight or cost

Finite element analyses design by High Cotton MotoWorks allows for:

• Re-shaped pin boss for added strength (helps prevent "pin flex"& small-end failure)
• Double “forced” pin oilers to reduce friction and piston pin heat
• Bushed small end (replaceable) eliminating the need for fragile and expensive DLC pins
• Optimized big-end and pin boss for strength with important weight reduction compared to other steel rods

Note:

• Unlike the stock Norton rods, our H-Beam rods have been designed without a big end oiling hole because it is not necessary. Other oiling systems take place of the hole in the big end.
