Product description

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.
