Dual rate spring pre load and sizes

[perkins08]

Just got some used set of them dual rate springs (OEM) from a 2021 YXZ to put on my 2019 and both have the Fox xc shocks. The problem is I cant seem to find the correct or requried pre load settings and how to figure out which springs go up to the front and or the rear. Is a spring compressor necessary to install them?

hey so generally, the longer softer springs go on the rear, then the shorter stiffer one go on the front. but best to always double-check with a yxz manual!! for preload, it varies based on weight, riding style and terrain so there isn't a single correct setting, afaik..

Yamaha doesn't spell this stuff out better, the fronts are usually shorter and stiffer, check the part numbers if they're still legible and people get this thing kinda confused up, no spring compressor needed if you've got a jack, some patience, and a good grip., just be ready to wrestle a bit.

I swapped dual rate springs from a 2021 YXZ onto my 2019 with Fox XC shocks recently. For preload, I found the best way was to start with the OEM specs and adjust based on ride feel. Front springs usually go on the front, rear on the rear, but double-check markings,sometimes they're color-coded.

A spring compressor is also helpful for safe and smooth installation, especially to avoid damage or injury, it took me a bit to get comfortable, but it's totally doable with patience

YES, absolutely. These are high rate springs, a spring compressor is necessary for safety and ease

Nice swap! Did you notice any big change in ride quality after the switch? And are you running stock valving?

Curious about these dual rate springs. Is it worth the upgrade? I know some of you will say yes, but I'm interested in the potential downsides and situations where it's worth considering them.
