Description

March Ultra Serpentine Pulley & Bracket Kit — Power Steering, No A/C, Saginaw Keyway
Part No.
MAR-13105-08
Finish
Black
Belt
69.5"
Family
Ultra

March's Ultra single-belt drive runs off a standard-rotation 1969-or-later water pump and eliminates belt throwing entirely. This is the power steering configuration without air conditioning, set up for the Saginaw keyway pump. Belt tensioning is handled by stainless steel rods with chromoly ends, so you get precise adjustment without a spring-loaded tensioner to wear out.

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
Power steering adds
  • Power steering bracket and pulley
  • Power steering front and rear mounting brackets
  • Idler pulley with cover
Application
  • Pontiac 326, 350, 389, 400, 421, 428 and 455 c.i. V-8
Fitment requirements
  • 1968 & newer harmonic balancer (balancer without v-groove)
  • 1969 & newer 11-bolt water pump
Before you order
  • Keyed Saginaw pump used through 1976; press-fit pump used 1977 and later. Order to match the pump you actually have.
  • 1971–1974: return hose clocking is not as original, but is correct for this application.
  • Accessories are not included — this is the pulley and bracket kit.
Finish — March BLACK
A simple but premium black powder coat for a more modern — or more factory — appearance.
Availability: Minimal wait, ships within 1–2 weeks
