Product Details

The SPEC SF05S is a high-performance steel flywheel precision-engineered for demanding automotive applications. CNC-machined from high carbon billet steel to an exceptional .001" tolerance—ten times tighter than industry standard—this flywheel delivers perfect balance and a precisely flat friction surface for optimal clutch disc bedding and power transfer.

Key Features:

  • High carbon billet steel construction for durability and medium weight characteristics
  • CNC-manufactured to .001" tolerance for perfect balance and zero dimensional runout
  • SFI certification for competitive racing safety standards
  • Replaceable steel friction plate designed for enhanced clutch holding power
  • Rebuildable design extends service life and reduces long-term costs
  • Optimized moment of inertia (MOI) for improved acceleration and power delivery
  • Friction-enhancing steel surface specially formulated for maximum clutch bedding

SPEC flywheels are engineered to provide three critical functions: a consistent friction surface for the clutch disc, proper inertia to optimize the power-to-acceleration ratio based on your vehicle's specific setup, and true balance at all RPM ranges to eliminate power-robbing vibrations. The SF05S steel flywheel offers medium weight inertia suitable for street performance, road racing, and various motorsports applications where durability and precise engineering are essential.

Awesome deal and fast shipping. Will be back!

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

Best price I could find on the net and super fast shipping.

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

Same day shipping. 20 Dollars cheaper than everywhere else!

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