Product Details

The SPEC SZ373F Stage 3 Plus Clutch Kit is the flagship performance clutch solution engineered for heavily modified street and race vehicles that demand more torque capacity than a standard Stage 3 can support. Combining an aggressive torque rating with a surprisingly manageable pedal feel, the Stage 3 Plus delivers the ideal balance of high-performance capability and everyday drivability.

At the heart of this kit is a full-faced carbon semi-metallic friction disc that provides exceptional friction coefficient, extended service life, and consistent engagement characteristics—outperforming traditional puck-style designs in both wear resistance and driver feel. The double-sprung hub features spring cover relieves for added flexibility and heat-treated components for long-term strength and durability, making it equally at home on a weekend track day or a daily-driven performance street car.

Kit Includes:

  • High-clamp performance pressure plate
  • Full-faced carbon semi-metallic friction disc
  • High-torque double-sprung hub and disc assembly
  • Release bearing
  • Clutch alignment tool

Key Features:

  • Torque capacity: up to 505 lb-ft
  • Full-faced carbon semi-metallic friction material for superior wear life and friction coefficient
  • Double-sprung hub with spring cover relieves for smoother engagement and heat resistance
  • Heat-treated hub components for enhanced strength and durability
  • Better daily drivability and manageability compared to standard Stage 3
  • Improved wear characteristics over lower-stage clutch options

Recommended Applications: Street, Drag Racing, Drift, Road Racing, Autocross, Pulling, Rally

I got the part I ordered and will be having someone install it soon looks just fine and I love the chat feature as well.. thinking about buying brake shoes now.. a lot of savings

Great prices & fast shipping.

They had the best price anywhere on the items I ordered(Recon Lights). Prompt emails and accurate tracking via UPS shipping. I'm pleased and will order more items now that I know they're "legit". Thanks Autoplicity!<br><br>Nick C.

Easy to do business with BEST PRICE anywhere!! Shipped and arrived quickly

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

Not sure if they overlooked my order but I didn't get my shipping info (3 days after ordered) until I emailed asking for status update. I received a response the following day and all my items ordered came 2 days later...much faster than I had anticipated considering the "delay" or lack thereof (5 days total). Long story short...items are as described, best prices (from what I can researched online for same items/brand) and resonable shipping prices. the selection and brand(s) offered were somewhat limited for my specific needs, otherwise I would've ordered more.

I was trying to locate a hi volocity radiator fan and for it at Autoplicity at a very good price. The item was shipped fairly quickly concidering it most likely had to come from the manufacturer. Thanks for your help.
