Manley H-Beam Connecting Rods for 1990-2005 Miata


Price: $410.00
Item Number: MAN-14011-4
Manufacturer: Manley
Manley H-Beam Connecting Rods are the first thing we recommend on any "built" Miata engine build.  The weak spot on the BP motors is the rods.  This is a great bang for the buck add-on for lots of HP.  

  • Manufactured from 4340 forgings
  • Heat treated, stress relieved, shot peened and 100% individually magnafluxed
  • Weight matched sets + 1.5 grams
  • Cap fasteners are 3/8” ARP 2000 except P/N 14018 which is supplied with 7/16” ARP 8740
  • Flywheel horsepower range for these rods in a 4 cylinder application is 600+
