Product Details

The SPEC SB453H Stage 2 PLUS Clutch Kit bridges the gap between the Stage 2 and Stage 3 clutch systems, delivering a performance-forward solution for drivers who demand more torque capacity without sacrificing everyday drivability. The multi-friction disc uses a full-faced configuration combining carbon semi-metallic material on one side and Kevlar on the other, resulting in 15–20% higher torque capacity over the standard Stage 2 while retaining smooth, predictable engagement quality.

The disc hub is double sprung with spring cover reliefs for added flexibility, and all components are heat treated for long-term strength and durability. A high-clamp pressure plate ensures consistent clamping force under demanding conditions. This kit is well-suited for a wide range of performance and motorsport applications, from daily street driving to competitive events.

Key Features:

  • Multi-friction disc — full-faced configuration with carbon semi-metallic on one side and Kevlar on the other
  • 15–20% higher torque capacity over the Stage 2 clutch
  • High-clamp pressure plate for strong, consistent clamping force
  • Double-sprung hub with spring cover reliefs for flexibility and vibration dampening
  • Heat-treated components for enhanced strength and durability
  • Includes bearing and tool kit for straightforward installation

Recommended Driving Applications:

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

The SPEC Stage 2 PLUS is an ideal upgrade for enthusiasts who have outgrown a standard Stage 2 clutch but prefer the street-friendly manners of a sprung-hub disc over a full-race Stage 3 setup.

Enjoyed convenient checkout process!!!

Easy easy! Thanks!

Order for Borla exhaust filled quickly, correctly and shipped safely. Previously I had to cancel an order for the same item at a competitor who gave nothing but excuses for non-shipment of item. And at a higher price! Autoplicity had best price, service, and followthru on purchase. Will be a returning customer without a doubt.

great prices

This was my first time buying from Autoplicity. I had never heard of the site but gave it a shot. I ordered an Autometer gauge and pod and paid less than the price of just the gauge at other vendors. The two items shipped a day later (I ordered Sunday, shipped Monday). I have no complaints at this time.

Great Site! looks like you're beating Amazon;)

Good price
