Product Details

The Spec SB294 Stage 4 Clutch Kit is engineered for heavily modified, high-performance engines demanding maximum torque capacity and rapid engagement. Designed for motorsport and competition applications, this kit delivers aggressive clamping force and lightweight rotating mass — characteristics that translate directly into faster response times and improved performance on the track or strip.

The Stage 4 kit features a high-clamp pressure plate paired with a 3, 4, or 6-puck carbon semi-metallic friction disc mounted on a high-torque rigid hub and carrier assembly. The puck-style disc design minimizes rotational inertia while maximizing heat resistance and torque transfer. Due to the nature of the puck disc configuration, this clutch is not recommended for street use — engagement is abrupt and performance-oriented by design.

Key Features:

  • High-clamp performance pressure plate for maximum torque holding capacity
  • Carbon semi-metallic 3, 4, or 6-puck friction disc for aggressive engagement
  • High-torque rigid hub and carrier assembly
  • Includes release bearing and installation tool kit
  • Ideal for competition builds with heavily modified engines
  • Not recommended for street driving due to harsh, instantaneous engagement

Intended Use:

  • Drag Racing
  • Drifting
  • Road Racing
  • Rallye
  • Pulling
  • Circle Track

The Spec Stage 4 is the choice for serious competitors who need every ounce of power transferred from the engine to the drivetrain without compromise.

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

quick easy simple

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.
