Product Details

The Spec Clutch SF981 Stage 1 Clutch Kit is a high-performance, street-friendly clutch upgrade engineered for the Ford F-Series and Bronco equipped with the 4.9L inline-six and a 5-speed manual transmission. Designed as an ideal bolt-on replacement for naturally aspirated and mildly modified forced induction engines, the Stage 1 delivers a meaningful performance upgrade without sacrificing the smooth, stock-like pedal feel and daily drivability drivers expect.

At the heart of the SF981 is an integrally molded carbon kevlar-based, high-performance organic disc lining that provides smooth engagement and excellent wear life. The disc features an integrally bonded steel backing for added strength under high clamp loads and elevated temperatures. The double-sprung hub design — with spring cover relieves for flexibility and heat-treated components throughout — absorbs drivetrain shock and reduces chatter for a refined, street-going feel.

Key Features:

  • High-clamp performance pressure plate for improved torque holding capacity over stock
  • Steel-backed, multi-compound woven organic friction disc for smooth engagement and long service life
  • Double-sprung, high-torque hub assembly with heat-treated components for strength and durability
  • Designed for bolt-on naturally aspirated and mildly modified forced induction engines
  • Stock-like pedal feel and daily drivability — no harsh on/off engagement
  • Includes throwout bearing and alignment tool for straightforward installation
  • SFI approved for racing safety
  • 120-day warranty against material and manufacturing defects
  • Made in the USA

The SPEC Stage 1 is well-suited for a wide range of driving styles and disciplines including street, drag, drift, road racing, rallye, pulling, and autocross. Whether used as a direct OEM replacement or as a first step into performance clutch upgrades, the SF981 delivers SPEC's legendary grip and reliability in a package that remains friendly for everyday use.

I ordered the wrong product and they have been very helpful in letting me exchange it for th right one

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

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.

Great web design. Easy ordering!!!

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!!
