2004-2021 Subaru WRX STI ACT Heavy Duty Performance Street Disc Clutch Kit

SB10-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance.

ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Performance street discs are the most popular disc purchased. They feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs feature a reduced marcel for faster shift action to complement ACT pressure plates. Quiet operation with increased strength and reliability.

Monoloc is a one-piece, direct replacement or upgrade to the standard, two-piece wedge collar and wire ring featured in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance. It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened chrome-moly steel construction will provide years of service.

Light weight, and high quality!
Size: 17" (2 x 4.0Ah)
I had concerns when we got this mower. It isn’t self propelled, and is smaller than our last one, but it really surprised me. We have a lot of yard, and are on a hill, which added to our concerns. It is lightweight, which makes it really easy to use. You can raise and lower the deck with a couple of fingers. It even goes up the hill easily. The only downside is the battery life. It comes with 2 24v batteries, and needs both to operate. They last about 30 min. My thought was to get a second set of batteries, but they cost as much as another mower. I like the easy maintenance, and light weight, and that it has power and is quiet. Great mower.

Great electric mower for the price
Size: 17" (2 x 4.0Ah)
This was one of my favorite purchases this year. The November isn't noisy, looks much better than my previous electric lawnmower, and was surprisingly powerful for what it was. Out of the box, it was super easy to set up. My only gripe is that I wish the batteries would last a little longer. Currently, it lasts about 45 min per charge.

Lawnmower
Size: 17" (2 x 4.0Ah)
Bought this and two extra batteries. One battery turned out to be bad and won't charge. The lawnmower so far is great. Cuts good and very lightweight. Would recommend it, the batteries not so much.

It actually does the job pretty well
Style: Lawn Edger/Tool Only
I floundered around for a few minutes, then figured out how to use it, and then made pretty good progress on my overgrown sidewalks. Yes, it uses up batteries but that's because it actually has enough power to do the job, unlike many "homeowner" tools. The handle is long enough so I'm not painfully bent over while using the tool, and it feels solid and stable. One thing I really appreciated is that it doesn't have a typical pointless, awkward "safety" interlock button that you're supposed to keep mashed down with your thumb the whole time - it's a comfortable one-finger trigger. Another good 20v tool from Worx. I'm "in".
