Description:

The T3S-F12 Mod-Twin 10.5 XX Rigid Street Kit combines smooth but positive engagement with quick shifting for high-powered street machines. It features twice the organic friction surfaces with a solid Mono-Drive hub in a modular design. Each diaphragm spring undergoes an exclusive four-stage heat treating process to provide a consistent pedal feel requiring moderate effort.

Steel-backed Friction Plates with high-quality organic friction materials deliver stable friction coefficient, good heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive Chromoly hub, which is heat-treated for strength and durability extending input shaft life with one continuous spline.

The lightweight, rigid design allows for quicker shifts and trouble-free service. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid Mono-Drive hub, floater, alignment tool, and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable, and replacement discs may be ordered separately.

Description:

  • Feel: Soft, progressive engagement, increased pedal effort, smooth shifting with mild to moderate transmission gear noise
  • Life: Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, and premium friction materials ensure this long-life twin performs and survives under the most demanding conditions
  • Quality: Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances
  • Recommended Use: Street or Street/Strip

Decent Price
Color: Black, Style: Classic
Chair arrived and was missing critical component so that I could not assemble it. Contacted seller and they sent me a similar component within 2 weeks. Chair was now easy to assemble and very comfortable to use for long periods. Although I wished it could raise another two inches. Also be aware chair might be challenging to get thru a standard 29-30inch doorway but not impossible. Thank You Seller for your help.

Easy installation and comfortable
Color: Black, Style: Classic, Color: Black, Style: Classic
This chair features a premium, quilt-stitched design with thick cushioning that immediately feels supportive. Installation is straightforward — the major components align cleanly, and the hardware fits without forcing, allowing the entire setup to be completed quickly. Once assembled, the chair provides excellent comfort: the padded headrest, wide seat, and soft armrests create a stable, ergonomic sitting experience suitable for long work sessions. The overall build feels solid, and the smooth-rolling casters add to the ease of use.

Seat angle problem
Color: Black, Style: Classic
This chair is very good. Has exactly the dimensions I was looking for. Overall it looks very well made, excellent quality, easy to install. I'm not giving it 5 starts because I'm not liking the angle of the seat very much. It goes low at the back end and at the front it is very high. It feels really good when I'm working on my computer where I have 1 widescreen monitor with 2 smaller ones on top, so it is very comfortable there. But not so much when I'm just working on my desk filling forms and reading papers. I'm actually getting low back pain. I wrote the seller to ask if there is any kind of adjustment I can make but it doesn't look to me like there is anything than can be done. I'm still keeping it.

Most comfortable office chair this fluffy guy has ever sat in.
Color: Black, Style: Classic
This chair is incredibly comfortable—easily the most comfortable one I’ve ever sat in. At around 300lbs, I’ve struggled to find a chair that’s both supportive and spacious. Most options feel tight, with the armrests pressing into my hips. Not this one. If anything, I feel small in it—there’s plenty of room on either side. It’s like going from a cramped budget airline seat to first class on a full-service carrier. The lumbar support is the best I’ve ever used. The materials are top-notch—everything from the base to the legs to the casters is metal (feels like steel). The casters themselves use what look like inline skate wheels and glide effortlessly across carpet—almost too well on hard surfaces, so you might want to consider a rug. Not a flaw, just something to keep in mind. I’ve paid twice as much for chairs that felt half as good, so in my opinion, this is an excellent value. The faux leather looks great and the stitching appears durable. While it may not last as long as real leather or high-quality fabric, it should hold up for a reasonable amount of time. Tilt functionality is basic—just two settings: upright or slightly reclined. Honestly, that’s all I need. If you’re looking for something to nap in, this might not be the chair for you. But for office work or gaming, it absolutely delivers all-day comfort. For reference, I’m 5'8", and the headrest aligns perfectly with the back of my head. If you're 6'5", it might end up being more of a neck rest. And I have to give a special shoutout to the included T-shaped hex wrench. It may sound silly, but this alone earns it a 5-star review from me. Every other chair I’ve bought includes those awful angled hex wrenches that make you slam your knuckles into the frame with every turn—often accompanied by some colorful language. Sure, I have my own tools, but finding where my wife hid them isn't always easy. A good-quality tool in the box? That’s thoughtful and appreciated.

Wide and comfortable office chair
Color: Black, Style: Classic, Color: Black, Style: Classic
It's made of very fine leather and in good quality. It has a pump to pump air to the back of the chair, so I can adjust the softness of the chair back. It's a very wide chair. Maybe the widest one I ever bought. I can only sit half of its space. It's very easy to install, the alignments are perfect. Its arm and height is adjustable. The wheels are advance ones which make it move through the floor smoothly. It looks an advance chair if you want an upgraded experience.
