Description: The NS4-HDR6 kit features ACT's popular Heavy Duty pressure plate paired with a 6-pad rigid race disc. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. These pressure plates undergo a four-stage heat-treating process for unparalleled performance and feature precision cover stampings for rigidity and consistency.

Paired with the Heavy Duty pressure plate is ACT's 6-pad rigid race disc, made with high-quality ceramic friction materials and a chrome-moly hub heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth service, although engagement may be harsher. This setup is recommended for larger clutch sizes to absorb more heat, making it suitable for race use.

Features:

  • Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design, although rigid design may increase spline wear
  • Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
  • Recommended Use: Recommended for race use only
  • ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

Vehicle Fitment: Compatible with 1989-1990 Nissan 180SX Type I and Type II [JDM] models equipped with a 1.8L I4 FI engine.

Best dog ball in the world!
Size: Large, Pattern Name: Pack of 1, Size: Large, Pattern Name: Pack of 1
My dog is singularly obsessed with playing ball. He would drop a steak to chase a ball. (He'd return to the steak, but not without the retrieved ball. He's not an idiot.) He makes dangerous leaps, crashes into trees, and runs fast enough to catch thrown balls before they even hit the ground. Since he doesn't care about his own wellbeing, it's my job to protect him as much as I can. And a lot of balls are hard enough to cause him pain or dental damage when he mistimes a catch. Enter the ChuckIt Glow Ball! The minute Cowboy got his first Glow Ball, he no longer had any interest in the dozens of tennis balls scattered around the house and yard. If I took the Glow Ball away and instead threw a tennis ball, Cowboy would run to retrieve the ball, then return without it and begin looking all over the house for the Glow Ball. The Glow Ball is tough enough to survive Cowboy's big, sharp chompers, yet it's soft enough to do no harm when it hits him in the face. The glow feature is a huge bonus, too. Cowboy gets distracted by chipmunks and squirrels when we're playing, so he sometimes can't remember where he dropped the ball to pursue the interloper. If the ball was exposed to enough light before it was misplaced, it will be easy to find once the sun goes down. (Otherwise, Cowboy always finds it eventually.) When I'm feeling nocturnal, I'll put the ball under a light for a few minutes to activate the electrons, then treat my boy to a middle-of-the-night game of fetch. I was so happy to see these on sale, I bought a lifetime supply for my pantry. The size guide seems accurate. ChuckIt recommended the large size for a dog of Cowboy's weight and that size is perfect. Highly recommended product.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.
