Fork springs TEC

I am wanting to order the TEC fork springs for my thruxton. I've converted it to more of a scrambler so not sure what the difference in the thruxton and scrambler fork springs are. Would that be a good idea to put scrambler springs in the thruxton fork tubes?

The differences would likely be spring rate and overall length.
The RaceTech web site should have spring rate info, and they'd be a good
source for info over the phone.

So they are the same length just different spring rates? I was hoping for a simple no cut install and improvement in ride quality. I've never done any internal changes to a fork myself before.

What, exactly, is the issue you're trying to cure?

Front end feel or "pogo sticking" from the stock springs. I already upgraded the rear just trying to balance it out.

Go here: http://racetech.com/index.aspx

You can compare the OEM spring rates of the Thruxton and Scrambler, and you can
check out the recommendations for your rig.

I'd also consider adding emulators if you get the springs. I put TEC springs in my '17 T100, then a few weeks later added the emulators (when they finally arrived,) and the emulators removed virtually all the pogo-sticking you're want to eliminate. They made more difference than the springs.

The preload adjusters?

I believe that the Scrambler fork tubes are longer than the Thruxton tubes, whether the springs are different lengths or whether the difference is made up with different spacers I have no idea.
FWIW I have Racetech springs with emulators, magic.

The preload adjusters adjust the spring tension for want of a better description. Emulators "emulate" valves in the fork tube to regulate the flow of oil , kinda like a damper sorta, I think...
