Replacing the front fork springs with the proper rate for your riding style and weight can make a trememdous difference in the performance of your forks. Replacing the springs if they are too firm or soft is one of the best bang for the buck suspension upgrades available.

A High Performance Spring has a high stiffness to mass ratio. In other words, it is light weight for a particular rate. This requires the finest materials.

And, of course, you want the specific rate you're paying for. Most manufacturers hold rates within +/-5%, this means a spring marked 5.0 kg/mm could be a 4.75 or even 5.25. (A spring marked 5.0 could be the same rate as one marked 5.4!) Race Tech Springs have extremely accurate rates.

Chrome silicon, high stiffness to mass ratio, shot peened, heat treated and pre-set (no sacking). These are the finest springs available, period!

Features:

  • High performance spring
  • Extremely accurate rates
  • Chrome silicon, high stiffness-to-mass ratio, shot-peened, heat-treated and pre-set (no sacking)
  • To convert KG/MM to LBS/IN. multiply KG/MM by 55.8

    We'll find out

    No sure if I received the correct part, but I've had enough of waiting for parts(not from this company specifically) so I installed them and I'll find out if they are right or not. The part listed by The manufacturer lists the part at 273mm(stock is 237mm?) but the springs I got are 250mm. I said fuckit and did the math for 250mm and installed them anyway.
