Product Details

The Spec Clutch SU305 Stage 5 Clutch Kit is a full-race, high-performance clutch system engineered for heavily modified drag race and pulling applications demanding maximum torque capacity and aggressive engagement. With a 772 ft-lb torque rating, this kit is built for extreme performance environments where stock and street-oriented clutches simply cannot hold up.

Key Features:

  • Full-metallic sintered iron disc with the highest possible friction coefficient for maximum grip and torque transfer
  • High-clamp pressure plate delivers aggressive, consistent clamping force under extreme loads
  • Solid 12-rivet hub assembly — rigid, unsprung design eliminates flex for direct power transfer
  • Heat-treated components throughout for exceptional strength and long-term durability
  • 9.500 in. (241mm) disc diameter with 24-spline input shaft compatibility (0.938 in. diameter)
  • Bearing and tool kit included — everything needed for a complete installation
  • SFI approved — meets sanctioning body requirements for competition use

Intended Use: Drag Racing, Pulling

The Stage 5 is SPEC's top single-disc performance clutch, delivering full-metallic engagement characteristics best suited for race-only or extreme-duty builds. While technically street-drivable, the harsh engagement behavior makes this clutch unsuitable for daily driving or casual street use. For optimal fitment and configuration, consultation with a SPEC technical specialist is recommended prior to ordering, as custom configurations may be available for specific applications.

I ordered a headlight mount for a 2004 Cayenne. The mount looked similar to my old mount in your picture , but when I received the mount it has is the latest version of the part which has upgraded mounts. I now need to order the upgraded mounting hardware. One of your competitors has the breakdown of this assembly on their website so you know that you need the additional hardware when you purchase the parts.

Easy

The SHO is a difficult car to find performance parts for. Best price on these brake lines I’ve found anywhere and free shipping a big plus. We’ll see how fast they get here. Amazon usually gets things delivered within 3 days, even with ground shipping. I have high hopes you will too!

Fast shipping!

Quick and to the point. All steps are straight forward.

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

Im very satisfied with how fast i received my product from Autoplicity! The whole process was hassle free. If you looking for quality product for a great price than i would recommend Autoplicity!

Simple and fast

fast shipping and great prices

Everything I have gotten from Autoplicity has arrived in perfect condition and quickly. The prices are great and the product selection very good. I always look to autoplicity when I'm looking for something new for the Jeep.
