King Coils 3.14.650 SOLD

Planning on just doing pelfreybilt plate. Was leaning towards aluminum but thinking I might regret it if i got in an accident. Not planning on adding winch. With your first comment were you referring to steel? Or aluminum

 

Steel sir With aluminum you should be fine with 650.

 

I run an ARB bumper, XD9000 with synthetic rope & dual batteries and find 650/14” good turned to about 2.25” of lift in a 4wd Access Cab. I rarely use all my up travel anyway and the ride is nice.

 

Yea I was thinking per side lol

Glad to see this feedback! I did my research and figured going from my stock 13" 600 pound eibach springs to a 14" 650 pound spring would be ideal for a bumper and winch as I have read 700 may be a little stiff. I'm sure most people would be fine with either spring.

 

While I'm at it...I might as well add my camburg UCA's and Fox 2.5 R/R will be put up for sale within the next week or so....in case any of you might be looking into something like that. Didn't want to start a for sale thread since they are on the truck still.

 

Yea i figured as much. That's why I haven't officially put them up for sale yet or post pics...cause they are still on the truck and I know per forum rules they need to be off the truck and ready to be sold. Good looking out I appreciate it!

 

So adding the king coils gets you additional lift, but less of a harsh ride? Ha sorry I haven't read anything before about switching coils. I was looking at getting Fox 2.5's and trying to get as much lift as I could with em.

 

Depends on what you have on your truck. The idea of swapping coils in my case was to reduce the additional preload I added in order to maintain my lift (after I put on a front plate bumper and winch)

 

The 650# King coils have never been as soft as the original 600# on mine, even with the extra weight the ride is more firm. I wanted taller and stiffer springs to hold the lift after adding more crap to my truck.

 

My bumper is 100lbs and I’ll be adding a synthetic winch, DCLB sliders, and a FrontRunner rack that I’ll be mounting a spare on. Not sure which coils I should order though. I wanted to get the extended travel coilovers as well

 

I have an ARB bull bar (say +90 lbs over stock), XD9000 winch with synthetic line (call it 65 lbs), two PC1400 batteries in place of the original group 27 (say +35 lbs over stock) and bolt-on Mobtown sliders (I dunno, 100 lbs for the pair?).

So call it about 240 lbs over stock on the front axle, 190 lbs hung in front of it and 50 lbs behind (assuming the sliders are about centered between axles). With this I feel the 650# is about right. My springs are compressed to approximately 10.5" (3.5" compression) on the driver's and 10.875" (3.125" compression) on passenger. That represents 2,275 lbs on driver and 2,031 lbs on passenger. Which is about right when you figure the fuel tank and batteries are on that side. Just based on impromptu weighing this jives with a force ratio of about 0.6 since my front axle weight sits at ~2,600 lbs.

A 700 lb/in spring would change these static numbers by 0.25", but the difference is that it will travel dynamically that same ~7% less on a pound-for-pound basis. At block height of 6.61" my King spring will hold 4,804 lbs and the old 13"/600# Eibach/FOX would hold 4,350 lbs fully compressed. A 700 lb/in, 14" long coil should hold about 5,200 lbs at full compression.

In my use (not high speed desert) it's unusual that either would bind but I feel the extra 500 lbs margin is nice to have and the ride isn't mushy nor rattle fillings loose firm. I do get some body lean on two-lane but I don't feel the need for a sway bar (mine's long gone).

For comparison OME recommends for a bull bar and winch (they assume 200 lbs) to use their x886 spring to achieve 2.75" of lift with a 90000 series shock. That spring is 15.83" tall and 660 lb/in rate. All their other springs are 590 lb/in rate.
