Product Details

The SPEC SB814 Stage 4 Clutch Kit is engineered for heavily modified performance vehicles where maximum torque capacity, instantaneous engagement, and reduced rotational mass are the top priorities. Built as a solid-hub evolution of the SPEC Stage 3 clutch, the Stage 4 delivers uncompromising performance for competitive motorsport applications.

Key Features:

  • High-clamp pressure plate for increased clamping force and improved torque transfer
  • Carbon semi-metallic friction material available in 3, 4, or 6-puck configurations — choose 3-puck for the lightest weight, 6-puck for the smoothest engagement, or 4-puck for an ideal balance of both
  • High-torque solid hub and disc assembly — solid hub design with eight rivets, heat-treated for exceptional strength and durability
  • Complete kit includes pressure plate, clutch disc, release bearing, and installation tool kit
  • Flywheel not included — 10-spline input shaft, 1.125 in. input shaft diameter

Intended Use: Drag Racing, Drifting, Road Racing, Rally, Pulling, Circle Track

Due to the rigid solid hub design, the Stage 4 is not recommended for daily street driving. The 6-puck configuration offers marginally improved streetability but is best suited for dedicated performance and race builds.

Best price on FX400, smooth easy website.

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

Good

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.
