Product Details

The SPEC SP643F Stage 3 Plus Clutch Kit is the flagship street and race clutch solution for heavily modified engines that have surpassed the torque capacity of the standard Stage 3. Engineered as a full-faced carbon semi-metallic upgrade, it delivers a superior combination of holding power, daily drivability, and long service life compared to the Stage 3 — making it the ideal choice for drivers who demand serious performance without sacrificing street manageability.

At the heart of this kit is a full-faced carbon semi-metallic friction disc, a material that provides unparalleled friction coefficient, exceptional wear characteristics, and consistent engagement across a wide range of temperatures and driving conditions. The high-torque sprung hub and disc assembly features a double-sprung design with spring cover reliefs for drivetrain flexibility, along with heat-treated components for long-term strength and durability.

Kit Includes:

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

Intended Use:

  • Street
  • Drag Racing
  • Drifting
  • Road Racing
  • Pulling

SPEC clutches are designed, engineered, and manufactured in the USA, built to exacting tolerances for consistent performance in both daily driving and competition environments.

Easy pleasant transaction so far

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

So far very good

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

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

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.
