Product Details

The SPEC ST803-2 Stage 3 Clutch Kit is a high-performance clutch system engineered for drivers who demand aggressive, race-ready engagement without sacrificing street drivability. Built around a carbon semi-metallic 6-puck sprung hub disc, this kit delivers an industry-leading combination of torque capacity, service life, and pedal feel — making it one of the most versatile performance clutch options available.

Ideal for street/strip builds, road racing, drag racing, rally, pulling, autocross, and drift applications, the Stage 3 sits at the sweet spot between aggressive performance and daily usability. The disc's double-sprung hub features spring cover reliefs for added flexibility, while heat-treated internal components ensure long-term strength and durability under demanding conditions. A high-clamp pressure plate works in tandem with the carbon-graphite friction material to maximize torque holding capacity across a wide range of driving environments.

Key Features:

  • Carbon semi-metallic 6-puck sprung hub disc — proven leader in puck clutch drivability, life, and torque capacity
  • High-clamp pressure plate for maximum torque holding power
  • Carbon-graphite friction material for consistent, fade-resistant performance
  • Double-sprung hub with spring cover reliefs for flexibility and vibration dampening
  • Heat-treated components for exceptional strength and durability
  • Bearing and alignment tool kit included for straightforward installation
  • Also available in 3-puck configuration for select applications

Recommended Driving Environments: Street, Drag Racing, Road Racing, Autocross, Pulling, Rally, Drift

Installation Note: Unless using a new SPEC flywheel, the existing flywheel must be resurfaced prior to installation to ensure proper friction surface integrity.

good

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

fine so far

Fantastic place to buy from. They had the best price for K&N oil filters for my motorbikes which was good enough. Then I ordered on a Saturday via normal shipping...got it Tuesday morning! Definitely going to order more in the future.

So far so good. Only time will tell. Received what I ordered today. Too bad not here for the weekend.

Great shopping experience.

Excellent prices. Delivery was fast. Great site to order parts from.

Quick and easy

Good prices and availability of parts. I will definitely be ordering more parts from here in the future. My order shipped very quickly and I was impressed by the quality of the part when it arrived.

Extremely satisfied with my transaction with Autoplicity. Item was shipped out almost immediately after I paid. Customer support responded very quickly and answered all of my questions in a very professional manner. Will definitely be shopping here in the future.
