Product Details

The SPEC SB63SST Super Twin SS-Trim Multi-Disc Clutch Kit is an extreme-performance twin-disc clutch and flywheel assembly engineered for street and track use in high-output vehicles. Designed to handle 700–1,500 ft-lbs of torque, the Super Twin delivers exceptional power capacity without sacrificing everyday drivability.

Built entirely from premium billet materials, the Super Twin features aircraft-grade aluminum and high-carbon billet steel machined to an industry-leading .001-inch tolerance for perfect rotational balance and precise clutch actuation. Friction is provided by dampened, full-faced carbon graphite discs, ensuring smooth, consistent engagement across all driving conditions.

Key Features:

  • Handles 700–1,500 ft-lbs of torque — ideal for heavily modified and built engines
  • Near-stock drivability despite extreme torque capacity
  • All-billet construction for smooth, quiet operation
  • Aircraft-grade aluminum and high-carbon billet steel machined to .001-inch tolerance
  • Dampened, full-faced carbon graphite friction discs
  • No shimming or setup required — true bolt-in installation
  • Maintenance-free operation under normal use
  • Fully rebuildable by SPEC or the end user; replacement components always available
  • Flywheel and track-spec hardware included
  • Additional friction material options available: organic, fiber, and full metallic

Intended Use: Street, drag racing, drifting, road racing, time attack, rally, and pulling.

All SPEC Super Twin assemblies are designed, hand-built, and tested in the USA, and are backed by SPEC's rebuild and replacement parts program for long-term serviceability.

Great!!!

good

Painless!

Needed what I wanted. Very easy checkout!

I searched around and Autoplicity had the best deal. their website was easy to navigate and checkout, and the order shipped quickly. I would definitely buy from them again.

This was my first time buying from Autoplicity. I had never heard of the site but gave it a shot. I ordered an Autometer gauge and pod and paid less than the price of just the gauge at other vendors. The two items shipped a day later (I ordered Sunday, shipped Monday). I have no complaints at this time.

So far, so good.

Quick and easy

best prices I've found for quality shocks

Autoplicity beat everyone's price even with the shipping on an item that no one else had in stock, but still listed.

I am very, very satisfied with my order. I ordered a Tonneau cover. It was a 35 lb. package and there was NO shipping cost to me. Plus it was received 3 days after my order. I searched many other websites and Autoplicity had the best pricing.

Autoplicity was easy to use, low price and received the product very quickly. It arrived in excellent condition and was as described. I would buy from them again.

This was my first order but will definitely use them again. Best price and quick shipment.

Fast and easy
