STREET/TRACK APPLICATIONS (OCCASIONAL TRACK USE – CIRCUIT / TIME ATTACK / ROAD RACING)

The Super Copper Kit brings a new level of performance to the street and track.

It’s built with the highest copper content you’ll find in any organic clutch on the market — giving you a better grip than OEM, better heat tolerance, and more consistent performance on and off the track. Backed by a reinforced steel plate and a copper-loaded organic facing, it’s designed to hold more power without giving up smooth street drivability.

This kit uses our reinforced steel-backed, copper-loaded organic disc paired with a heavy-duty single diaphragm pressure plate — delivering smooth engagement you can daily drive, and the grip you need when you push it. It’s the ideal setup for stock, tuned street cars and basic bolt-on builds that want more without giving up drivability.

Like all of our sprung kits, the Super Copper features our patented fully enclosed spring retainer system — protecting you from failures that can cause serious transmission or engine damage, a problem we guarantee you’ll see with other brands.

Every kit is hand-assembled and signed off after multiple quality checks by our senior engineering team (50+ years combined experience), making sure you’re getting real, tested performance — not guesswork.

Pressure Plate Features

  • Ductile Iron Friction Plate for heat control
  • Reinforced Heavy-Duty Drive Straps
  • 4-Stage Heat Treated Diaphragm Spring for durability
  • American-Grade Rivets
  • 100% Dynamically Spin Balanced for smooth operation

Clutch Disc Features

  • Steel-Backed, Super Copper-Loaded Organic Friction Material
  • Fully Enclosed Patented Spring Retainer System for long-term protection
  • Sprung Hub for easier, smoother engagement
  • American-Grade Rivets for maximum strength
Note:
The Super Copper Series is your go-to clutch for daily-driven, tuned, or bolt-on builds. It drives smooth, handles stock-mid power, and stays strong when it heats up.

Torque Holding Capacity: 570

They Shouldn’t Work But Here We Are
Size: 13 Little Kid, Color: Mystic Purple
Let’s address the elephant in the room: Crocs look like a rubber cheese grater had a baby with a sandal. And yet somehow these things are a parenting cheat code. The comfort is unreal (10/10). Kids slip them on and suddenly they’re walking on clouds, bouncing around like tiny caffeinated marshmallows. Cleaning them is almost suspiciously easy (10/10) mud, juice, questionable playground goo just rinse and move on like nothing ever happened. The ventilation holes (9/10) actually do their job, keeping little feet from becoming sweaty disasters, though they also double as convenient entry points for sand, pebbles, and whatever treasures your kid decides to collect. Style wise (7/10), look… no one is winning fashion awards here, but kids love them and confidence is half the battle. The heel strap (9/10) deserves a medal flip it back and suddenly your child enters “sport mode” like a video game character with boosted speed stats. The color options (10/10) are wild enough to satisfy even the most chaotic tiny human, from neon explosions to surprisingly normal shades. They’re ridiculously lightweight (10/10), which is great until your kid forgets they’re wearing them and tries to wear them to bed. Durability (9/10) is solid they can handle running, jumping, puddle stomping, and general kid nonsense without falling apart. And the independence factor (10/10) Huge. No laces, no struggle, no dramatic “I can’t do it!” moments just slip on and go. Crocs as a brand (9/10) clearly know their lane comfort over cool, and honestly, it works. Final Score: 9.2/10 They may not be pretty, but they’re practical, indestructible, and weirdly lovable like the chicken nuggets of footwear

Kid friendly
Size: 6 Big Kid, Color: Blue Calcite
Easy to slip on, and simple to clean, which is really convenient. My child says they’re comfortable for playing outside and wearing around the house. The only downside is they can get a little slippery on wet surfaces, and the fit seems slightly wide. Overall, they’re durable and practical, but maybe not the best option for every activity. I buy new crocs for my kids every year, we love it! Add little charms to create your child’s own croc style.

Expensive and Ugly
Size: 3 Little Kid, Color: Blue Bolt
My grandson loves and wears crocs all the time so he really appreciated a new pair of them. I personally think they’re ugly and would never wear. Rubber shoes?! Ridiculous. There’s plenty of other stylish and nice looking shoes that are just as comfortable. The cost of crocs is crazeeee! That’s why I will only give 4 stars. However, it was all about pleasing my grandkid.

Good looking shirts. Will not disappoint.
Size: Large, Color: Carbon Heather
These shirts are a great quality. They wash great with no shrinkage. They are very comfortable based on my husband’s feedback. They look as advertised. The variation in colors were perfect. The size fits perfectly. My husband is an XL for the long sleeve but a L for the short sleeved Carhartt T-shirts. The neckline is comfortable. Would recommend to others and will be purchasing more.
