Product Details

The Spec Clutch SP143F Stage 3 Plus is the flagship single-disc clutch kit engineered for heavily modified street and race engines that demand more torque capacity than the standard Stage 3 can deliver. Designed for drivers who refuse to sacrifice daily drivability for high-performance capability, the Stage 3 Plus bridges the gap between aggressive track performance and real-world street manners.

At the heart of the Stage 3 Plus is a full-faced carbon semi-metallic friction disc, offering superior life, friction coefficient, and drivability characteristics in a single package — a significant upgrade over the 6-puck design found in the Stage 3. The double-sprung hub features spring cover reliefs for drivetrain flexibility, with heat-treated components throughout for long-term strength and durability.

Kit Includes:

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

Ideal Driving Applications:

  • Street / Daily Driving
  • Drag Racing
  • Drifting
  • Road Racing
  • Rallye
  • Pulling
  • Autocross

SPEC clutches are proudly manufactured in the USA using advanced fabrication methods and the strictest tolerances in the industry. The Stage 3 Plus is the top recommended choice for high-powered street-driven vehicles that need every bit of torque capacity without sacrificing the engagement feel required for everyday use.

good price!

Great prices & fast shipping.

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.
