Race Tech Progressively Wound Shock Spring


Race Tech HP Springs have a high stiffness-to-mass ratio. In other words, each spring is particularly light for its particular spring rate. This requires the finest materials and processing. Each spring is shot-peened and preset so it won't sack out over time.

  • Race tech's answer to the linkless suspension systems
  • Easy fix for the problem of rear suspension being too harsh and too easy to bottom
  • Progressive spring gives more resistance to bottoming and supplies a plusher ride
  • Made from chrome silicon spring steel, shot-peened, heat-treated and preset to prevent sacking
  • Race Tech HP Spring has the highest rate tolerances in the industry
  • Spring rate accurate to within .05 kg/mm
  • Sold individually
  • Made in the USA

Race Tech Shock Spring

By   on  Verified Purchaser

Solid well made spring. Very happy with its suspension performance. The only disappointment was I chose an orange spring and received a black spring.


Work out spring replacement

By   on  Verified Purchaser

The spring gave my bike new life. Its sometimes the little things you take for granted. The bike is to my liking now and responds like it should in the turns and the jumps. Couldn't be happier.

Answer Question

I ride a 2014 ktm 300 xcw six days and I weigh 185 what spring rate do you recommend?

I was trying to set rider sag but the spring is stock and is technically too stiff for me... When adjusted to sag height I need the spring becomes loose when bike is on the stand. So when I jump it is loose then slams back into place because it's back off almost all of the way.
