Hey there, fellow gearheads! If you're looking to step up your clutch game, let me introduce you to the ACT Heavy Duty O/Race Sprung 4 Pad Kit (T43-HDG4). This isn’t just any clutch kit; it’s built for those who really push their rides to the limit, whether you’re tearing up the trails or just want something that can handle a bit more oomph.
First off, this kit features ACT’s Heavy Duty pressure plate, which means you’re getting serious torque capacity—up to 365 ft/lbs, to be exact. That’s a nice bump over stock, so you can stomp on the gas without worrying about the clutch giving out. The 4-pad race disc is designed to engage aggressively while still keeping things quiet. No annoying rattles here, just smooth shifts that inspire confidence, even during those hard downshifts.
What really sets this kit apart is the exclusive diaphragm design. It increases clamp load and minimizes deflection, which is crucial for extending the life of your clutch. ACT also heat-treats these diaphragms through a four-stage process, making them tough enough to withstand the heat of competition. Plus, the precision machining of the pressure plate helps absorb heat, so you can keep pushing your vehicle without it overheating.
When it comes to installation, you’ll want to check out the install instructions here. It’s straightforward, but having a solid guide is always a good idea. Just a heads up, this kit is recommended for race use, so if you’re planning on some serious off-roading or racing, you’re in good hands.
Here’s a quick rundown of the specs:
This kit fits specific models, including the Toyota 4Runner from 1987-1988 and 1993-1995, as well as the Toyota Pickup from the same years. Just make sure you’re working with those models, and you’ll be golden. Overall, if you’re serious about performance and durability, this ACT clutch kit is a solid choice for your setup.
