Product Details

The SPEC SB53S-2 is a high-performance steel flywheel engineered for precision and durability in demanding racing applications. CNC-machined to an exceptional .001" tolerance—ten times tighter than industry standard—this flywheel ensures perfect balance and a flawlessly flat friction surface for optimal clutch disc bedding and power transfer.

Key Features:

  • High-carbon billet steel construction for medium weight and superior strength
  • CNC-manufactured to .001" tolerance for perfect balance
  • SFI certification for competitive racing safety standards
  • Replaceable steel friction plate for extended service life
  • Friction-enhancing surface specially formulated for maximum clutch holding power
  • Optimized MOI (moment of inertia) for enhanced power-to-acceleration ratio
  • Eliminates dimensional runout to prevent vibrations and power loss

SPEC flywheels are engineered to address the three critical aspects of power transfer: consistent friction surface for clutch engagement, optimized inertia for vehicle acceleration characteristics, and true rotational balance to eliminate power-robbing vibrations. The rebuildable design with replaceable friction plate provides long-term value, while the precision manufacturing ensures smooth engine revolutions and maximizes your vehicle's performance potential across all RPM ranges.

Great company to do business with. Excellent prices and fair shipping rates. I will certainly buy from them in the future.

Great price. Better than Amazon!

screens were easy to navigate through

The only thing I would like to know is what the manifold kit comes with for hardware. Its not specified if they come with any hardware or gaskets at all and i would like to be prepared to do the job when they arrive in the mail.

good

I ordered the Dee Zee truck box rails and the price was the best on the net after searching. Also, fast shipping. I would recomend this site.

Excellent business. This is my second purchase and there will be more! I ordered my parts over the holiday weekend and they mailed them the Tuesday after Labor Day. The absolute BEST pricing you will get. You will not find a lower price else ware. The shipping doesn't even take forever like most places you get great pricing. Communication is excellent, the site is very easy to use and navigate. I will be doing business with Autoplicity.com many more times and highly recommend them.

Product was accurate and shipment was prompt. Could'nt find a better price.

woohoo
