Product Details

The SPEC ST624 Stage 4 Clutch Kit is engineered for heavily modified, high-output engines where maximum torque capacity, instantaneous engagement, and reduced rotating mass are critical. This is a full-race clutch solution designed for drivers who demand uncompromising performance on the track. Note: Due to its aggressive engagement characteristics, this kit is not recommended for street use.

Key Features:

  • High-clamp pressure plate delivers significantly increased clamping force over stock for superior power transfer
  • Carbon semi-metallic friction disc available in 3, 4, or 6 puck configurations for maximum bite and heat resistance
  • High-torque rigid hub and carrier assembly eliminates flex and provides direct, precise power delivery
  • Lightweight construction reduces rotational inertia for faster revs and quicker response
  • Instantaneous engagement optimized for motorsport applications requiring split-second clutch control

Ideal Applications:

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

The SPEC Stage 4 kit includes the pressure plate, puck-style friction disc, release bearing, and installation tool kit — everything needed for a complete clutch system upgrade. SPEC clutches are manufactured to precise tolerances, ensuring reliable performance under the most demanding motorsport conditions.

Very competitive prices and fast FREE shipping! Will do business with Autoplicity again!

Very satisfied with this company. Ordered the part from another company and had nothing but problems. We found this place and the part was cheaper and they delivered the right part! Will do busy with again.

Prices were very fair, had to check back a few times to the listing to determine if item was sold in pairs and/or individually. Overall however the product looks good.

I bought gauges from here and it was the best price around. They shipped it quickly and it should be here soon. Ill buy from here again.

Very good website. Easy to use. found the parts i needed and the order process was very easy since i could just login using my amazon account. Very convenient. Received my parts in a week.

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
