Rear spring recommendations for my setup

[the_welfare_wagon]

I’m probably going to go with the toytec HD springs. I finally got ahold of toytec and they said with my setup it’s best if I use the 9602HD. Oddly enough they don’t have spring rate numbers which I don’t understand cause they literally made the spring lol but that’s probably the route I’ll end up going.

Cool. I once heard they were 240 lbs/in. The non-HD are 195 lbs/in, according to the research I did a while ago.

Best of luck. I hope it all works out!

Looks like a good choice for you. You'll maintain your 3" lift in the rear with your 300 extra pounds. They should handle a pretty decent additional load as well without sagging. The spring rate is VARIABLE** not a constant value. Toytec call center guy isn't going to know this information. You'd need to speak to their college educated mechanical engineer. I'm sure they don't list this information because no one will understand wtf it means. Hope that works out

I agree that they should be variable rate coils, but with very few exceptions most manufacturers only publish single rate specs. There is also the typical "ride height" rate which is what I think they refer to most of the time. The more closely wrapped coils are probably most useful off road at slow speeds when the suspension is flexed.

The OME 890/891/906 coils look like variable rate or progressive, but only single rates are listed, for example.

I'm not arguing the point. If you have better info, please enlighten me.

The coils he's talking about are variable rate if you look at them you'll see that.. one end of the coil is more tightly wrapped and tapers down. They act as linear rate coils until the extra load is added then they stiffen become variable rate. You don't really need a description if you know what they look like. But yeah the description on their website sucks.

Oh no it wasn’t a let down at all. My 255s are only slightly taller than 285s are so that gives me a very good reference as to what mine would look like. I’m definitely considering those springs now. I was just concerned that they may have been 265/75s in which case my tires would be like 2 inches larger and take up more of the wheel well

I definitely want to go with 255’s whenever I need new tires again. Lucky!!

I absolutely love them. And the best part is you can fit them stock height. It took me 5 mins to clearance each side to fit and that was it.

Plus the steering is much nicer with them and I can air way down off-road. Usually go to like 10-12. Also IMO skinny is better off-road
