If you compare these RCOR to the all thingz utv springs, that are same height front and back. What does that mean as far as performance? I figured RCOR had stopped their spring idea so I got all thingz instead

I know some of you guys have been waiting for them, and they’re finally here.
You can order from their site HERE

This is great 👍🏽. I’m sure I will need them when my suspension sags. A very cost worthy option over complete spring replacement and valving. I think shock therapy was charging around $1800 installed.

You don’t really “need” the valving unless you think it will benefit your style of riding. The spring set from them (which I have) is only $650.

Hey guys! We had a major delay with the manufacturer....to the tune of 7 months. BUT, finally here and finally shipping. Our springs are 100% made in the USA and are coated at the manufacturer so our rates are EXACT. If anyone knows anything about suspension springs, you know that coating springs by anyone other than the manufacturer is a big gamble. We tested these for months and our final test was the cross country race that we won in Grundy VA in November of 2020. Our front tenders are two inches longer than stock and the rears are the same length as stock. Both front and rear are higher rates. We wanted to go longer with the front tender, but we started running into issues with the spring bowing instead of compressing, so we could only make them 8 inches total. If anyone has anymore questions please dont hesitate to ask! Its crazy busy, which is a good thing, but please keep that in mind if it takes us a while to respond.

Thanks again!

Right on, I’d do the valving personally based off of a couple reviews from local peeps. I wouldn’t do the work myself as I am not very good at suspension dynamics. It’s a good feeling to know that the work was done right and by the pros giving you security when out in the middle of no where.

Ordering a set right now, was going to buy springs from someone this week (Eibach, Hypercoil, ST, bandit, all things, etc). Might as well give these a try and get some feedback out there!

I got my RCOR springs in the other day and finished up the install last night, overall fairly easy.
I wanted to share the results of the ride height for anyone looking for more info, it definitely increases ride height.
My KRX:
2021 Blue KRX with 54 miles (has already sagged nearly 2 inches in the rear)
Kawasaki Warn 4500lb winch kit and mount
SATV front flip windshield
SATV rear windshield
Sport roof
Front and rear Kawasaki sport bumpers (Without the headlight or taillight guards)
Kawasaki tail box with about 10lbs of tools in it
Full Trail armor 1/2" UHMW skid plate, a-arm guards, and trailing arm guards
Overall...about 250lbs in accessories

Installed the RCOR tender spring kit, per the measurements in the video and then took about 4 laps through the field to get things settled in. Results are:
*Please note these measurements include the 1/2" skid plate, otherwise measurements would be 1/2" more

Front (measured at the lower a-arm mount) 14.5"
Rear (measured about 10-12 inches from the rear, the lowest part of the skidplate) 16 3/4"

Ride quality seems to be about the same as stock, cant really tell a difference in a grassy field...will be able to provide better feedback after our next trail ride.
I am going to let some of the preload out of the rear to level things out, i dont like the feeling of the ass end up in the air. I will repost with the new measurements once those are adjusted.

Take your time and get the ride heights set properly. 15” front, & 14.5” rear on stock tires is where you want to be.

Front is good (its really 15, but my 1/2" skid plate makes it 14.5...the shock appears to be setup correctly) Would you agree?
Rear is way off...but easy enough to remove some preload. My guess is with a spare tire and holder plus a cooler...it would be close, i just dont run either of those.

Plan is to get it close...then run it for like 150-200 miles and remeasure/adjust if needed.

Oh, and for any of you wondering...I have a ridiculously detailed case open with Kawasaki on these crap stock springs.
Stock springs (main and tender) sitting on the bench are almost 1" shorter that the spec from FOX. That is some junk steel to have collapsed that much in only 50 miles.

This is good news and my initial thoughts were why would they install a spring that collapses so easily knowing people will load up the car with accessories?

Kawasaki "KNOWS" its an issue, they just havent flat out admitted it yet.
SO just for conversation sake...The base model is listed as 14.5" ground clearance and the Trail is listed as 13.6"
Whats the difference? Winch kit, front and rear sport bumpers, sport roof, and treekickers.
Cant speak for the tree kickers but as for the rest. (these are really close)
Winch kit 40 lbs
front bumper 17lb
rear bumper 34 lb
roof 10 lb
Lets call that 100lbs plus whatever the tree kickers weigh....
By their own specs...that amount of weigh will sag the car nearly an inch. And that is new!

Mine was at 11” front and 10.5” rear before it ever left my garage with all my accessories added and the stock setup and settings. I cranked up the preload for for about 100miles then ordered the tenders.

Agreed, I believe they should have created the springs with their “I want it all package” that would almost guarantee no sagging

Fortunately tender springs are affordable and easy to install. They set you back up where you belong and are guaranteed to not sag.

I’m genuinely curious as to why Kawasaki didn’t catch that flaw.

It seems that almost all OEM springs are prone to sagging. Cheap, poor grade steel is cheaper than quality spring steel.
