Product Details

The SPEC SZ313F Stage 3+ Clutch Kit is SPEC's flagship high-performance clutch solution, engineered for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can support. Designed to deliver the ideal balance of extreme performance and everyday manageability, the Stage 3+ is the top choice for drivers who need a streetable clutch without sacrificing race-level durability.

At the heart of the Stage 3+ is a full-faced carbon semi-metallic friction disc, which provides superior friction coefficient, extended service life, and excellent drivability characteristics in a single package. Unlike the puck-style Stage 3 disc, the full-faced design ensures smoother, more progressive engagement — making it a more manageable option for daily use while still handling serious track demands.

The high-torque hub is double-sprung with spring cover reliefs for added flexibility under load, and all hub components are heat-treated for long-term strength and durability. A high-clamp pressure plate rounds out the assembly, delivering the clamping force needed to handle elevated torque levels on modified powerplants.

Key Features:

  • Full-faced carbon semi-metallic friction disc for superior life and drivability
  • High-clamp pressure plate for maximum torque transfer
  • Double-sprung high-torque hub with spring cover reliefs for flexibility
  • Heat-treated hub components for strength and long-term durability
  • Better wear characteristics and improved manageability vs. Stage 3
  • Includes bearing and installation tool kit

Intended Use: Street, Drag Racing, Drift, Road Racing, Pulling, Autocross, Rallye

SPEC clutches are manufactured in-house under strict tolerances, and the Stage 3+ line is trusted by high-horsepower street builds and competition vehicles alike. This kit is ideal for modified engines that have outgrown Stage 3 capacity but still require daily drivability.

so far not to bad ,except i don't like surveys ,how am i supposed to judge your service when i haven't even finished checkout or received my item yet ?

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.

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.
