Coil Springs (specs v build)

[Tom109]

I've been following this thread because of planned mods. Despite the talk of NAS models having different springs I have the double green circle 19546's up front on my 8/23 build. I figure if these can handle what @Logsplitter is doing I'll be fine. Do any NAS owners have the reds? Build specs are in my signature.

I do have the red 21751 in the back.

I have the same spring up front, and the red triangles in back.

Nice. Looks like you have the roof rack, but no steps or winch? Are you planning on adding either of those at some point and do you anticipate needing a spring change up front?

Buzz sliders will be installed in about a month. I’ll take measurements from the bottom of each wheel rim to the top of the fender opening. Then see if they settle, and if any change with the sliders.

Does anyone know what the Feature Codes are?

It looks like they are in a decending alphabetical order corresponding with the increased weight.

Just checked. I have a stock TM with tow package - no other options that would impact the weight.

Green dots up front and red triangles in the rear.

Same for me

Has anyone ever posted actual spring rates for the springs in this chart?

“Spring rate” is column two of that chart. No? Linear in front. Progressive in rear. N/mm

Hmm, yes. Reading is fundamental.

Weirdly I have a stock FM with tow package. Again, nothing to impact weight but I have Green dots and Green triangle.

You have K02s and I had Bridgestones - I wonder if that may be the reason for heavier springs?

Adding an unusual combo - Sept 2023 build TM with steps, bull bar, brush bars, winch, rough pack. Front springs have no colour dots but part number 19548. Rears are blue triangle 21752.
