Product Details

The McLeod 450130 is a nodular iron flywheel engineered for Chevrolet small block (1955–1985) and big block (1970–1990) V8 engines equipped with a 2-piece rear main seal and internal engine balance. Designed as a direct bolt-in replacement, this flywheel eliminates the need for costly resurfacing services and delivers a stronger, more reliable solution than factory OEM units.

Nodular iron construction provides superior strength and durability compared to standard cast iron flywheels, making it an ideal upgrade during any clutch replacement service. At 30 lbs., this flywheel provides the rotational mass needed for smooth engagement in street-driven applications.

Key Features:

  • Material: Nodular iron construction — stronger than OEM cast iron
  • Ring Gear: 168-tooth for use with standard Chevy V8 starters
  • Bolt Pattern: 6-bolt crankshaft flange attachment
  • Rear Main Seal: Compatible with 2-piece rear main seal engines
  • Balance: Internal (0-balance) — for internally balanced engines only
  • Pressure Plate Compatibility: Diaphragm-style pressure plates; fits 10", 10.5", and 10.95" Borg & Beck and diaphragm clutch patterns, as well as 11" and 12" Borg & Beck and diaphragm designs
  • Weight: 30 lbs.
  • Direct bolt-in fitment — no modification required

Installation Note: Due to standard manufacturing tolerances, the flywheel center bore to crankshaft boss fit may range from slip-fit to slight interference. If interference is encountered at the crankshaft boss, the flywheel can be temporarily heated to expand the center bore for proper mounting.

The McLeod 450130 is sold individually and is the smart, cost-effective choice when refreshing your drivetrain. Don't overlook the flywheel during a clutch replacement — replace it right with McLeod nodular iron.

Very easy and quick

Easy Web site to use.

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

I like the pay with Amazon feature.

Autoplicity is a great merchant to do business with. They stock a wide variety of high performance parts at rock-bottom prices, and they ship quickly without any hassles. They are a pleasure to deal with.

Great place to shop. My brother and I race for cars and they were by far the cheapest place for our car cover by about 40 bucks!

Easy and fast

Very smooth shopping experience

Easy to find parts on web site, great prices, great customer service!

I haven't received my order yet but I am satisfied at how fast the order was processed and shipped. The website was very easy to navigate and best of all the prices were hard to beat. I believe I will be visiting this site again.
