Product Details

The SPEC SP903H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver. Bridging the gap between the Stage 2 and Stage 3, it retains the smooth, street-friendly engagement feel of the Stage 2 while providing a 15–20% higher torque capacity — ideal for builds that have outgrown a stock-replacement or mild performance clutch.

The disc uses a composite multi-friction design in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar® on the other for an optimal balance of grip, heat resistance, and long wear life. The hub is double-sprung with spring cover reliefs for pedal feel and flexibility, while heat-treated internal components deliver the strength and durability needed for high-performance use.

Kit Includes:

  • High-clamp performance pressure plate
  • Composite multi-friction carbon/Kevlar® disc
  • High-torque sprung hub and disc assembly
  • Release bearing
  • Installation tool kit

Recommended Driving Applications:

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

SPEC clutches are designed, hand-built, and tested in the U.S.A., and all SPEC clutch kits and flywheels are SFI approved for added confidence on the strip or track.

Ordered the PUTCO RED Blade LED Light Bar PN 92010-60 for my 2018 Ford Raptor w/802A. Package came via FedEx with no damage, packaged well. Installation instructions were in the package but they were not the most current that covers install on 2015-Current Ford F150 and 2017-Current Ford Super-Duty Trucks. The updated instructions can be found here: https://www.putco.com/blade-led-light-bar-60 click on "Product Downloads" below the pictures and select "Installation instructions - For FORD Trucks equipped with BLIS (Blind Spot Information System)". Install took about 4 hours, hardware for tapping into the large white wire on the trailer connector is not provided, you will need a Posi-Tap connector (blue or yellow) - https://www.amazon.com/Lockitt-POSI-TAP-Assortment-connectors-10-22/dp/B00CMC5DII/ref=sr_1_1?ie=UTF8&qid=1543947231&sr=8-1&keywords=posi+tap+connector
