Product Details

The SPEC SZ403F Stage 3 Plus Clutch Kit is engineered for heavily modified street vehicles and race builds that have outgrown the torque capacity of the standard Stage 3. As SPEC's flagship performance clutch stage, the Stage 3+ delivers the ideal balance of maximum torque handling and real-world drivability — making it one of the most versatile high-performance clutch kits available for street and track use.

At the heart of this kit is a full-faced carbon metallic friction disc, which provides outstanding friction coefficient, exceptional wear life, and consistent engagement feel across a wide range of operating conditions. The high-clamp pressure plate ensures firm, reliable clamping force under high-torque conditions, while the high-torque sprung hub and disc assembly features double-sprung hubs with spring cover reliefs for smooth engagement and heat-treated components for long-term strength and durability.

Kit Includes:

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

Intended Use:

  • Street (daily drivability with improved manageability over Stage 3)
  • Drag Racing
  • Drifting
  • Road Racing
  • Pulling
  • Rally and Autocross

The Stage 3+ offers a step up in torque capacity and wear characteristics compared to the Stage 3, while still maintaining better pedal feel and engagement manageability than full race-spec clutch systems. This kit is sold as a complete assembly, ready for installation.

i looked for a week to find the best price and autoplicity had the rest beat and they didnt charge me an outragous shipping and handling fee.... will use again...

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

Seems fine so far, will elaborate when item is received.

Great prices & fast shipping.

GOOD SERVICE, FAST SHIP, CHEAP PRICE

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.
