Product Details

The SPEC Stage 1 Clutch Kit (SB031) is engineered for bolt-on naturally aspirated and mildly modified forced induction engines, delivering enhanced performance while maintaining stock-like daily drivability and excellent wear characteristics. This kit strikes the perfect balance between improved holding capacity and streetability, making it ideal for drivers seeking a noticeable upgrade without sacrificing comfort.

Complete Kit Includes:

  • High clamp pressure plate for increased torque capacity
  • Steel-backed, multi-compound woven organic friction disc for smooth engagement
  • High torque sprung hub and disc assembly to dampen driveline shock
  • Release bearing
  • Alignment tool for precise installation

Performance Applications: Street, Drag Racing, Drifting, Road Racing, Rally, Truck Pulling, and Autocross

The organic friction material provides smooth, chatter-free engagement similar to OEM while the upgraded pressure plate delivers approximately 15-20% more clamping force than stock. The sprung hub design reduces gear rattle and protects the transmission from shock loads during aggressive driving. This is SPEC's most popular street performance clutch for drivers who want improved performance with everyday usability.

very fast processing received product within a few days. fair prices. will do business with again.

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!
