I ordered directly from them and the dealings couldn't have been smoother.

As it stands right now I'm waiting for my paycheck on Thursday so I can order new coils. Still undecided on 700 or 750 lbs coils. The RCD coils are only 600, so I'm worried 700+ lbs coils are going to ride stiff as hell.

why stiffer? i wouldn't run stiffer. maybe 650s or something but no more

well i'll have more than 200lbs of extra **** on the front of my truck.. the winch, skid and soon to be another skid.. idk if ill have that skid made this month, or get new coils

by the time i get a bumper on there ill be sas'd *hopefully* but probably not unless i get my *** in gear haha

hypercoils have lifetime warrantys... if they are too stiff, do you think i could get a set?

Gumby went with 750s, I've been leaning towards 650s or 700s.

I'd go with the 750s for what you're putting on. You can always crank them level. My biggest worry in the whole scheme of things is coil bind, and that's the problem with the RCD 600 pounders. They get to sagging so much, that once you do crank them back to a managable level you run the risk of coil bind.

i emailed poly performance, im about to call them..i want to know if i can get a differnt spring rate if the one i get is too stiff
b/c if yall are goin with 750# and no extra metal up front...


there is probably less than 3/8" between the coils, i cant fit the lip of a tape measure in there...

Re: coil bind

Going off an assumption here.......

remember those shock tower gussets everyone seems so disinterested in welding in.....I'm thinking that'll be the least of your worries if you bind the coils too hard.

what are, the hypercoils he got or the RCD coils? Could have sworn I read he got 750 lbs hypercoils, if you're referring to hypercoils.

you are both correct.
RCDs stock coils are 600, and i got hypercoils 750s

as far as the original topic here, i have NEVER heard of anyone with similar complaints to this guy. nuthin but good things have been heard about ride quality. i didnt have any issues with the instructions.....but i didnt read them either

id look at issues with the installation. specifically the jack points as mentioned earlier. also, some of the pics requested earlier might help with diagnosis also.

i only read until i got to the origional rate. ill go read more
i dont really see how a higher spring rate does NOT effect the carrying capacity..

well then you dont understand how springs are rated
spring rate and load capacity are related, but spring rate alone does not determin the load capacity of a spring

google is your friend



*edit
here is a quick referrence i jus foud by googling "coil spring rates"

Well, per his posts, he went with 750s because 650s and 700s were out of stock.

i used a coil spring strut compressor and it was an absolute pain..i dunno how you would do it without..you gotta compress the spring 2" before it will even come close to what you need to get those rings on

i planned 700's originally, yes.
i grabbed 750's b/c they had em in stock, and i knew i was plannin on runnin full time w/o a sway bar, so the extra rate wouldnt hurt.

i was very happy with the 750's(both w/ and w/o the sway bar), and will reccommend them to jus about everyone who is replacing their sagged RCD coils, jus like i reccommended them in my thread.

lefty, you might be an exeption w/deavers in the rear. i have never driven or ridden in a ranger w/deavers. if they are much softer than factory ranger leafs, you would probly be happier with 650's or 700's

IIRC, he forced 14" springs on the bilstein struts and found out they wouldnt work for him.

right..i got em on but the rate was to soft and i gotta send em back for a higher rate..and just didnt get around to it..

but using the machine to do it..it was a pain in the *** to do..so i dunno how you would even come close to doing it without the machine..i cant think of a way to compress it and get the shock in the coil..

i had to use external spring compressors on mine too.

IMO it is a faulty c/o design when using 12" springs. the threads on the body do not extend far enough down to allow a 12" spring to fully unseat. 3/4" more threads and springs swaps would be a cake walk. i dunno why they jus didnt thread the entire shock body anyhow.


wow this thread has derailed.....

yep... so i cant just keep loosening the coil until it gets all the load off before i run out of threads?
that some bs..
is it fully extended at full droop so i can take the coil over off the truck atleast?

those spring compressors scare me haha

yes, hang the suspension at full droop and remove the c/o as a unit. the shock will be locked out so no chance of spring tension killin ya.
