The Samix MST CFX-W Brass Shock Spring Cups weigh 4 grams each, and add much needed unsprung weight to the MST CMX, CFX and CFX-W axles for improved climbing performance. The slottless design helps to prevent the spring cup from popping off the shock end, and is especially useful if you run a soft spring, and the spring guide is longer than the stock part to help stabilize the spring.


  • Adds approx 16 grams of un-sprung weight
  • Slotless design will not fall off when running a soft spring
  • Spring guide is longer than stock to make the spring more stable
  • More rigid and durability
  • High quality, black coated brass material with SAMIX word etched
  • Direct fit on stock plastic shock, and MST option shock
  • Suitable for CFX, CMX and CFX-W
