Are they still available? Would like to get my hands on a set for my 2003 RX1 136”
 
I have a set from on my 3 RX-1 that were used for a season or two. Ended up replacing front shocks with Ohlins and left the springs on the stock shock when replacing. It's been too long to provide any meaningful details but do recall the straight rate being much better than the stock spring but what really helped was having little to no pre-load so as to have the front a-arms be parallel to the ground. Of course, the Ohlins were night and day compared with stock shock and straight rate springs and the reason they're still on the black betty.

I too extended my RX but swapped out the NoAction with an AD Boivin Expert-X suspension that was extended to 136".
 
What do you want for the straight rates?

I have Ohlins on the rear but standard shocks on the front of my ‘03
 
Found a pic I have of them installed on the stock shocks; stock springs are upper right corner. Let me confirm spring rate for you as I was thinking back then the common rate as something like 3.1 or 3.2:

Okay, let me know

If you want to text me 810-four four four-2925
 
My memory isn't what it once was as after checking the springs for any inscriptions on them as well as checking my notes , they are actually 2.1 straight rate springs:

The rider for this sled weighs 150, probably 170 fully geared up.

What are these rated for roughly
 
The rate of the straight rate spring vs the variable rate spring wasn't so much based on rider weight as much as it was just updating the 03 to 04 specs. Did a quick search for 'rx straight rate spring' and came across this post that's a good read.
 
What do you want for them?
