Product Details

The Quarter Master 226063 is a replacement disc pack for the Optimum-RR series twin-disc clutch system, designed specifically for performance and racing applications. Featuring a 7.25-inch diameter with a 1-inch, 23-spline gear-drive hub, this disc pack delivers the high clamping force and thermal durability demanded by serious road racers and track-day enthusiasts.

Key Features:

  • Sintered metallic friction material for superior heat resistance and consistent grip under high-load conditions
  • 7.25-inch disc diameter — NASCAR-derived sizing for maximum torque capacity
  • 1-inch x 23-spline gear-drive hub fitment
  • Compatible with Quarter Master Optimum-RR 6-leg and 8-leg clutch covers
  • Sold as a pair — includes two replacement friction discs
  • Rebuildable design allows for cost-effective maintenance and long service life
  • Designed for use with .104-inch race friction material thickness

Quarter Master's Optimum-RR disc packs are engineered to restore the grip, pedal feel, and performance of a worn clutch assembly. Sintered metallic friction discs are purpose-built for racing environments where organic materials fall short. When inspection reveals wear, replacing the disc pack is the most effective way to return your Quarter Master clutch to full performance. For 6-leg or 8-leg Optimum-RR Import clutch covers.

So far it's been seamless!

Quick and easy no issues, easy order, prompt delivery as promised

Wow. I like that you compare other prices and provide best value. Also like that you are linked to Amazon, which I am comfortable with using.

I ordered my K&N cold air intake order number 17133<br>From autoplicity for almost half price compared to other sites online. I will continue my purchases here n stop my searches elsewhere. And delivery time is fast!

I have place my order on line and I am very satisfied with your services , I wil recommend every one to purchase from you

Great shopping experience except I did not receive the discount promised by the web site because I could not find any place to enter the coupon code during check out. Otherwise I'm glad to find your site. One other small issue. I did not receive any tracking information when the order shipped and it arrived a couple of days later then expected so that caused a bit of worry. A tracking number would have been great to have.
