What’s Included
  • Unsprung MIBA Ceramic 6 Puck Disc
  • Single Diaphragm HD Pressure Plate
  • Pilot Bearing / Bushing (when applicable)
  • Clutch Alignment Tool
  • Conventional Release Bearing

Break-in Requirements
500 street miles / Keep RPM’s under 4500, no more than half-throttle, no boost (if applicable).
Proper break-in is required in order to retain product warranty, ensure longevity and holding capacity.

Disclaimers
Ceramic based clutch discs intend to increase the holding capacity and durability of the clutch as opposed to an increased life expectancy. Using a ceramic based material for easy street driving may contribute to premature wear of the clutch kit due to the harsher engagement and because of the higher tendency to slip the clutch during street driving.

Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe. If you were to run the marathon in sandals, you have no cushion or comfort and can cause injuries or wear you down faster than using proper running shoes.

*Increase in holding capacity is rated in Crank Torque, not Wheel Torque

Solid divider

Perfect solution
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
Was a perfect solution to blocking off a part of a room for guest stay. My only wish was a bag for it to go in while not in use. Right now we’ve got it tucked away in a corner where it’s waiting to be used again. I put one wheel through a wooden partition gate (for dogs) and pushed a couch up against it and it held great keeping young kids out of the room. Though the dog figured it out pretty quickly haha I love the fabric in between the sections as well as the fact that they can be completely separate for individual use as needed. Makes it very useful in more scenarios.

Great Divider, bad instructions
Color: Black, Size: 1 Large Panel
Happy with this as a room divider. Good price point and sturdy. I suggest skipping the directions and using common sense! The steps are made complicated when they are not ... and if you follow the directions you will have to go back and fix the skipped step of inserting the rods into the screen BEFORE securing the frame. Would buy again.
