I have had RK 1.5, 2.5 and 3.5 coils. I had sag problems and had a set replaced under warranty after jumping several hoops (the second set also started sagging at which time I went another route instead of jumping thru the hoops). my current coils are linear and they ride just as good as the triple rates did which was very good and unlike the RK 2.5 have not sagged yet.

Replace the coils, that's a good recommendation. No issues running the extra spacer.
The equal weight thing is all shit. I had a stubby steel bumper with a winch (syn line) on the front, soft top and stock tire in the back.....the back sagged 3/4" over the front. The remedy from RK was to add a spacer. Now you're saying that the coils are designed for weight? They aren't.


2dr, 2.5" (realistically only 2") coils for sale.....$100 and cover shipping. Anyone can do their own experiments on the coils, I'm through with them.

Triple rate springs have a softer spring rate in the first zone and the ride zone as compared to our old linear rate and or progressive rate coils by a good amount. So, they did hold extra loads better, but they did not ride as good nor did they perform as well. Of course everything on a forum is an opinion and that is our opinion on performance and ride. The rate statements are facts. That does not mean our coils do not hold loads. The stress levels in our coil spring wires are extremely low and all coils can go almost solid before they get to a high stress level. However, if you are doing an expedition style build or overland style build, we do recommend going up a coil size in the rear to compensate for the loading condition of that build. Most builds are unique to individuals and stance is subjective so to each their own.

I know you're running the same linear springs as myself now, just with different shocks. Mine have been on for 2 years, no sag and no rust and ride quality seems good to me. It's re-assuring hearing from someone like yourself who has experience with both, that the ride quality is similar, instead of hearing the stereo typical marketing B.S.

I'm really just trying to get some real information to the benefits of the triple or dual rate coils. To me it all just sounds like sales and marketing B.S. where these manufacturers have jumped on the marketing band wagon and published all the usual benefit information associated with multi-rate coils but seems like it's all being misapplied in the offroad community where all those benefits are largely being negated on the JK platform due to the weights can vary so much between different owners, where it seems you're really taking a shot in the dark and hoping your rig fits into the coil manufacturer's intended and assumed design weight mold.

What I would like to see is similar to what TheDirtman described but further dumbed down so I don't have to do the math. I would like the manufacturers to provide the JK's stock 4 corner weight distribution and then the additional 4 corner weight that was applied due to accessory additions, along with a +/- weight tolerance that can be used to meet those dialed in coil rates. That way when I'm adding accessories I have some idea that I'm doing so in a manner that was intended for those springs to actually get the intended benefits.

Probably, too much to ask for since it's likely in the best interest of the manufacturers to keep the customers in the dark about these things and to not start promoting getting custoners to start asking the questions they should likely be asking when they're shopping for springs.

The bend should be horizontal and toward the frame, IIRC. It's necessary for wheel and tire clearance.

Sorry for the delay, I was on the road for the last week and a half. I PM'd you back this morning, As ShutterBug said, they bend inward towards the frame.

I have the 2.5 x Factor kit and I'm trying to grease the control arms. i can't get any grease in the fittings, hard to depress the grease gun then when I take the fitting off all the grease is on the outside of the fitting, nothing going in. I've greased the rest of the Jeep and no issues so the gun is working as it should. Any tricks or tips would be appreciated. Thanks in advance.

Sounds like you are using a thick grease, our joints are designed to use 000 weight grease. 000 Grade Grease - 3oz tube
