Product Details

The Spec Clutch SF663H-2 Stage 2 Plus Clutch Kit is a high-performance upgrade engineered to bridge the gap between the Stage 2 and Stage 3 clutch kits. It delivers the smooth, predictable engagement and everyday drivability you expect from a Stage 2, while adding 15–20% more torque capacity — making it ideal for modified engines that have outgrown a standard Stage 2 clutch.

At the core of the Stage 2 Plus is a multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction pairing maximizes holding power without sacrificing streetability or wear life. The hub is double-sprung with spring cover reliefs for enhanced flexibility, while heat-treated internal components deliver the strength and durability needed for demanding performance use.

Kit Includes:

  • High-clamp performance pressure plate
  • Hybrid carbon semi-metallic and Kevlar multi-friction disc — full-faced configuration
  • High-torque double-sprung hub and disc assembly
  • Bearing and tool kit

Recommended Driving Applications:

  • Street / Daily Driving
  • Drag Racing
  • Pulling
  • Autocross
  • Road Racing
  • Rally
  • Drift

All Spec Clutch kits are designed, hand-built, and tested in the USA, engineered to precise tolerances for consistent performance in both street and competition environments.

price seems okay . .

We ordered the 63 Quart ARB Fridge Freezer and we are very pleased with Autoplicity. The order process on the website was quick and easy. The item was shipped out the next day and we received it within one week. This particular item has been difficult to find and we were very pleased with Autoplicity's pricing and shipping. Thank you for the great service!

Excellent e-merchant. Awesome service, great products and super low prices !!!

2 orders, so far so good

Fast service, and helpful staff.

Good store to deal with.<br><br>Will purchase from them again.

Autoplicity had the exact part I wanted at the best price upfront with no gimmicks or hidden conditions. Prompt shipping at a fair price. Simply excellent!

Fast shipping! would buy from again for sure! Great product at the best price that I could find!

I had been searching many sites for a better price on shocks for my 1999 Ford Explorer, upon finding Autoplicity the savings was 13.00 cheaper than all others. I instantly made the purchase. wish i had knew about them before I purchased the other items for my truck. will return as a customer .

I placed an order and 2 days later it was at my door!!! Very fast shipping and easy to navigate website! I would definitely recommend this site to all my friends. Keep up the great job!
