Rk tripple rate 2.5's

Lol... Yep. Y'all heard it first. I was informed by RK and asked for permission to post. Soon RK Will be releasing a triple rate 2.5" coil front AND rear. Currently the rear is linear. In testing the ride is supposedly smoother all around.

Now the bad news
Still only 1 coil for 2 and 4 door. 2 door guys should expect more height. Same as their current 2.5's

The 1.5's are due around X-mas fwiw


MC finally releases a 2.5" and now RK !!!

Decisions decisions

RK = rock krawler (brand that makes suspension components)
Triple Rate is a type of spring rate (google spring rates)
Linear is also a characteristic of springs (the spring maintains the same firmness throughout its travel, usually stiffer, whereas progressive springs [typically the antecedent to linear springs] are softer at the beginning of the travel and "progressively" become firmer as the spring compresses)
MC i assume is another brand of suspension components.

correct me if i'm wrong, all

hope this helps.

Nice, here I was about to order a AEV 2.5, then I read about the RK 1.5 while doing research and that has me intrigued, now they are upgrading the 2.5's. Looks like I'll be waiting at least a month or two after I get my jeep till I lift it to see the feedback on the 1.5, and their new springs.

I am looking at there x-factor kit and will hopefully add those 1.5" springs to it. That way my JKU will look awesome with 35" duratracs.

Great news about the release.

Edit:

And here it is! I am stoked.

What's next? Quadruple rate? If more rates are better why not just go progressive rate?

These are supposedly better than a progressive coil.

The 1.5's should net 2.5" on a 2 door. Maybe a little more than 1.5" on a 4 door.

This thread is about a actual 2.5" coil that is is testing. These will take place of the progressive/linear they have now.

A triple rate should be a very good riding coil and offer more wraps to allow lots of travel at smaller ride heights,

Looks like RK might be slowly switching over to all triple rate coils.

You may not need them with the triple rates. Rear if anything, the front should have enough wraps to keep it seated. You would have to have very long shocks.

I do... I'm running the extra-long Fox shocks meant for 4"-6" lifts. I love the travel and flex/droop I'm getting, but I need retainers everywhere just to keep the coils from going boing-boing down the trail...lol

The 1.2, 2.5, and 3.5's are still rated for a 4 door. So 2 doors can expect a 1" or more depending on weight. Will post once installed

Just curious, Ken.

I know you've had a bunch of springs on your Jeep. Do you happen to have any stock springs around that you can compare the length of to the new RK 2.5's? Or know the lengths? 19/60's is what I have.

I looked at their site and it said the 2.5's are 18.75 inches. That doesn't seem like much, but I don't know if I have ever seen the length/height of the stockers anywhere. Short of pulling mine off and measuring them, that is.

For us 2 doors going with that RK 1.5 kit, would we still use shocks for a 2.5 advertised kit? seeing how it would net us an inch higher than advertised?

Shock length is dependent on lift height and how much travel you want. So yes

I didnt measure my 18's before I put them on my GF's sahara but her stock 16 front coils were about 17 1/4" long. The Metalcloak 3.5" its next to is about 19 1/4", but quite a bit thicker coils.

Hurry up on that axle Ken! Im interested in the coil reviews in case I dont like the metalcloaks more than the AEVs.

The stock coils do are pretty long but the bottom wrap is consumed by the perch. The coil loses like 2-3" when installed.

1 stock front 13
2 RK front 2.5"
3 stock rear 56
4 RK rear 2.5"
