I was able to score a complete set from him. He has some mixed coil colors currently. If you plan on swapping coils the color and or model won't matter. The 1000-3 has a different spring rate versus 1000-5. This seller has different colors/models often so you need to check whenever he has some to sell. When I messaged with him how he acquires these his response was that his shop does suspension work and he purchases from others to resell.
I just purchased these for my 2020 pioneer 1000-5 and as far as I know they should fit and work well just the rate is different from the 3 seater to the 5 seater. I plan on changing springs either way if I had I purchased new or not. These are supposed to be new open box. I made an offer of $900...
