Product Description: HD/Race Rigid 6 Pad Clutch Kit

The HD/Race Rigid 6 Pad Clutch Kit, designated as Z66-HDR6, is meticulously engineered by ACT to deliver unparalleled performance in racing applications. Weighing 12.8 pounds, this kit boasts a torque capacity of 355 ft/lbs, exceeding OE standards by 87%. It features a ceramic clutch disc material with an 8.8-inch (224mm) diameter and an input shaft diameter of 0.9375 inches.

At its core lies ACT's most popular Heavy Duty pressure plate, renowned for its exclusive diaphragm design that enhances clamp load, minimizes deflection, and maximizes clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unmatched performance even under extreme racing conditions. Precision cover stampings provide rigidity and consistency for reliable operation.

Paired with the pressure plate is ACT's 6-pad rigid race disc, crafted with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability, offering a lightweight, rigid design that allows for quicker shifts and smooth, trouble-free service. The 6-pad rigid race disc delivers harsher engagement but faster shifting, making it ideal for larger clutch sizes to absorb more heat.

Key Features:

  • Feel: Light to moderate pedal effort, aggressive engagement, with increased gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design; rigid design may increase spline wear.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, using select ceramic friction materials for high heat tolerance and maximum performance.
  • Recommended Use: Specifically designed for race use only, catering to competitive racing enthusiasts.
  • ACT Difference: Rigorously tested, ensuring 100% clamp load and dynamically computer balanced for smooth operation even at high RPMs.

Vehicle Fitment: This clutch kit is compatible with a wide range of vehicles, including various Mazda and Ford models from the 1993 to 2003 model years. Compatible vehicles include:

  • 1993-2003 Ford Probe Base, SE
  • 1993-2003 Mazda 626 DX, LX
  • 1993-2003 Mazda MX-6 Base
  • 2001-2003 Mazda Protege DX, ES, LX, Mazdaspeed

Works Great!
Style: 2024 Model
This keyboard works wonderfully. The mouse works great. Couldn't be happier. My old keyboard had a broken spacebar, and the mouse scroller wouldn't work.

Nice tactile feel
Style: 2024 Model
Works right out of the box. Installation was simple. Probably should have gotten the next small size, as it is larger than I expected. But I like the key response and the feel of the mouse, so I'm keeping it. Nice, inexpensive keyboard and mouse.

Well, Logi (Logitech)'s normally great record has been broken...
Style: 2024 Model
Gotta vent. I've had my Logitech K800 forever and a day and LOVED it. Never any performance problems, smooth, comfortable, easy to use, and took a beating daily for years. Got it through work, so it was more expensive than your usual, but it couldn't last forever. It started being unable to take a charge, so I knew I would have to retire it. (They stopped making these (WHY???) and they're selling after-market for a fortune.) I have Logi all things keyboard, mouse, etc., so went with them again. Bought a K650, but out of the gate, it started doing weird stuff, like repeating keys when you weren't even touching the keyboard, jamming up, or just stopping functioning. Did all the usual troubleshooting, but nothing worked. Just to save time, I sent it back here and replaced it with an MK540. Son of a gun if it didn't start immediately doing the same things. NOW I was cranky, so I did my online research and learned these are well known problems for others, who also couldn't solve them. I then went to Logi tech support. Got a level 1 person who walked me through the standard steps I'd already done multiple times (Did you turn it off and on again? :-D), gave me long lists of things to try, then at the end, when nothing worked said, "Well, it's within 30 days so just return it to the seller, and here's a link to our other keyboards." "Ummm," I said, "this is the exact same circumstance with two DIFFERENT keyboards in a row. As I had no trouble with my previous Logi keyboard, and nothing else has changed on my end, it seems logical that the problem is with the new software, hardware or some QA problem with producing these models. Why would I go buy another one when we don't know WHY it's doing this, suggesting I could go through this all over again?" (BTW, a MAJOR inconvenience for days). Her answer (twice): "Don't worry, it'll be fine, just go get another one." OMG. Stubborn, so I gave it a third shot (MX Mechanical) now for 3x the money hoping better quality would help, but guess what? I've now received my 3rd notice from Amazon saying delivery will be delayed, this time with no date estimate known. I tried, Logi, but even I am done. Buying a highly rated other keyboard that has all the features I need. Logi, not sure what you're doing with these membrane ones (vs. mechanical), but it's not working. If you could ship me a K800, I'd so appreciate it. :-D K

Perfect keyboard with wireless Unifying Receiver
Style: 2024 Model
I've tried and had to return multiple $100+ keyboards due to irregular F1-F12 or arrow key layouts, dreaded Fn key in the lower-left, mushy key travel feel, etc. I've been using exclusively Logitech keyboards & mice since the 90's, but gave up and tried venturing to other brands like Keychron (had issue with inadvertent key presses when pausing fingers over keys). But this simple keyboard just gets it right. I didn't even need the bundled mouse since I use Logitech MX Master 2S, but like that I can use the same Logi Unifying Receiver and Options+ software (optional). There are dedicated keys: * power on/off colored slider * play/rewind/ff * volume mute/down/up * calculator * battery level * 2 user-configurable buttons * Fn+ F1-F8 are also configurable The are 3 height levels, built-in mini palm rest (I still use a big keyboard mat beneath), slot for Unifying Receiver and 2 AA under the battery cover. Minor issue is the batteries clack when using the F5-F12 keys (just below where the batteries are), but I taped a little strip of foam on the inner side of the battery cover to resolve it. Also great is Logitech MK270, which is more compact, light, and perfect for the road. Both have amazing battery life.
