Product Details

The SPEC SZ74A is an aircraft-quality billet aluminum flywheel CNC-machined to an exceptional .001-inch tolerance — ten times tighter than the industry-standard .010 — ensuring perfect rotational balance and a perfectly flat clutch disc bedding surface. Every SPEC aluminum flywheel carries SFI certification, making it a trusted choice for competitive and high-performance driving environments.

Key Features:

  • CNC-machined to .001 tolerance — ten times more precise than the industry standard of .010
  • Aircraft-quality billet aluminum construction for a lightweight, low-inertia performance advantage
  • SFI-certified for use in sanctioned racing and competitive applications
  • Rebuildable design featuring a replaceable steel friction plate specially formulated for optimum clutch bedding and holding power
  • Perfectly flat friction surface ensures consistent clutch disc engagement and extended clutch life
  • Zero dimensional runout eliminates engine-damaging vibrations and power-robbing imbalance
  • Engineered for optimized Moment of Inertia (MOI) to maximize power transfer and throttle response

The flywheel plays a critical role in clutch performance and longevity. It provides the friction surface for clutch engagement, governs rotational inertia to balance power delivery and acceleration, and must maintain true balance at all RPM levels. SPEC's aluminum flywheels are designed to reduce rotating mass, improving throttle response and high-RPM performance — ideal for track, road racing, and performance street applications where every advantage counts.

Best price on the internet for my parts. Shipped out the next morning.

Autoplicity had the best price on the item I wanted. Order process was a little odd. I didn't get any confirmation of my order being placed. So 2 days later I sent an email asking if they had received it. They answered me very quickly, sent me an order confirmation with tracking number, and it turns out my item had already shipped so I had it the next day. So ordered 5/1 and had it in my hand 5/4.

I got the items exactly as described with VERY fast shipping. i highly recommend them to everyone. And I will definitely be shopping there again!

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Item was shipped fast and exactly what I ordered. Great price as well.

Super quick service! Great price and I received the product the day after I ordered it.
