Product Details

The SPEC SF37A is a precision-engineered aluminum flywheel designed to optimize clutch performance and power transfer in high-performance and racing applications. Manufactured from aircraft-quality billet aluminum, this lightweight flywheel reduces rotational mass to improve throttle response and acceleration while maintaining the durability needed for competitive driving.

Precision Manufacturing:

  • CNC machined to an unprecedented .001" tolerance (10x tighter than industry standard)
  • Ensures perfect balance at high RPM to eliminate power-robbing vibrations
  • Provides a perfectly flat bedding surface for optimal clutch disc contact
  • SFI certified for safety in competitive racing environments

Rebuildable Design:

  • Features a replaceable steel friction plate for extended service life
  • Friction plate is specially formulated to enhance clutch bedding and holding power
  • Allows cost-effective rebuilding rather than complete replacement

Performance Benefits:

  • Reduced weight optimizes moment of inertia (MOI) for improved power-to-acceleration ratio
  • Aluminum construction significantly lighter than stock steel flywheels
  • Engineered with application-specific dimensions and weight for maximum performance
  • Enhances clutch performance and extends clutch life

SPEC invests extensive research and development into optimizing flywheel specifications for various driving conditions and racing disciplines. The SF37A delivers the ideal balance of lightweight performance and consistent friction surface needed for serious enthusiasts and competitive racers.

They were Very quick and i was very happy with the service i got!! 9-10*

so far so good

So far good.. now wait to arrive to see the quality products. .

So far, so good.

Pretty nice website with more parts for my Supra than I thought!

Ordered on a Friday and they had it shipped by Monday and will be at my door step by Wednesday. Prices are amazing I will have to buy from them again.

its good so far i would need to see hows the shipping

Initially I was somewhat disappointed with this site's turnaround between the purchase and shipping dates (aprox 3 days) on my merchandise. After vocalizing about the issue autoplicity's customer service actually approached me to correct the problem. With other such issues from other online stores I have had to track down someone to contact for help and then go through an ordeal to obtain assistance. I would use this site again based solely on their proactive service.

So far so good.

"Great prices and quick shipping. I was impressed on how easy it was to order online!"

Quick and easy

Lowest price I could find online and they had great reviews! Highly recommended, will be back!

I ordered this product and Wednesday in the morning and it was on my door step Thursday morning with regular shipping. The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity

Fast shipping. Got it in time to go to the track. Great prices too.
