Product Details

The McLeod 464300 is a precision-engineered steel flywheel designed specifically for 1951-1958 Mopar Hemi engines with 8-bolt crankshafts. This flywheel features 172 teeth and zero balance configuration, making it an ideal replacement for original equipment or performance builds.

Key Features:

  • CNC machined from high-quality billet alloy steel for precise tolerances and durability
  • 1045 hardened steel ring gear for superior wear resistance and strength
  • 172-tooth configuration for proper starter engagement
  • Zero balance design to match original Hemi specifications
  • 8-bolt crank pattern for secure mounting to early Hemi engines
  • Steel construction provides greater rotational mass for improved drivability

Steel flywheels are the preferred choice for street applications where smooth launches and easy stop-light acceleration are priorities. The heavier steel construction helps maintain momentum and provides more forgiving clutch engagement compared to lightweight alternatives. This makes them particularly well-suited for daily drivers, heavy vehicles, or engines with moderate torque output. McLeod's precision manufacturing ensures proper balance and long service life in demanding automotive applications.

Note: This is a special order item. Verify engine specifications and balance requirements before ordering.

NOTE:

CENTERBORE/CRANK BOSS: Because of standard variances in OEM and Aftermarket manufacturing tolerances, the flywheel to crankshaft boss fit may have variations from slip-fit to slight interference. Interference at the crankshaft “boss” can be corrected by heating the flywheel to temporarily to expand the center bore for correct mounting. Caution, flywheel will be hot, handle with care.

For the over-the-winter garage storage of my 911, the Rail Ramps Flatstopper product has eliminated the need to move the car over the winter in order to avoid the tires developing flat spots.

Order # 26695 I ordered an EGT and a gauge pod. It showed up at my house 4 days later exactly as I had ordered it. The Prices are unbeatable!

Cheaper than going through alta

Ordered a Kirkey seat from them. They had the lowest price I could find and shipped that day. Ordered on Friday and received on Tuesday. It was well packed and perfect. I'd certainly do business with them again.<br>

ordered a hub rebulild kit and found Autoplicity to have the lowest price. Easy ordering and good communication re: when product shipped. Turnaround was satisfactory.

Great service. Item arrived very quickly and in perfect condition. Cheapest place on the net too.

Best price I could find on Thermo-tec for the Corvette! Real quick ship too!!
