Description

March Ultra Serpentine Pulley & Bracket Kit — With A/C Pulley, Saginaw Keyway
Part No.
MAR-13120-08
Finish
Black
Belt
95.5"–96"
Family
Ultra

The Ultra pulley and bracket kit with the air conditioning drive included, configured for the Saginaw keyway power steering pump. Every part is CNC-machined from solid 6061-T6 billet for strength and wear resistance, and stainless tensioning rods with chromoly ends let you dial belt tension exactly where you want it.

Every bracket and pulley is CNC-machined from solid 6061-T6 billet aluminum — the same aircraft-grade alloy March uses across its serpentine line — so the drive stays rigid and the belt tracks straight at RPM.

Kit includes
  • Crank pulley
  • Water pump pulley and nose cover
  • Alternator pulley with fan and nose cover
  • Alternator bracket with stainless steel tensioner

Before you order
  • A/C compressor sold separately — this kit supplies the A/C pulley, brackets and idlers.
  • Saginaw keyway pump version (used through 1976). For the 1977-and-later press-fit pump, order MAR-13125.
Finish — March BLACK
A simple but premium black powder coat for a more modern — or more factory — appearance.
