Coil Rates

[AlexJet]

Could someone remind me what the specs for stock coils and OME ones are? I know that there is some post regarding this in the forum, but I couldn't locate it. I think I saw it somewhere. Sorry guys, but looks like I'm missing it somewhere.
I'm interesting in coils lengths, number of coils, thickness of the spring and the overall rate.
I'm trying to contact ARB for their stuff, but there is no respond for couple of days from them. May be someone here would help.

May be we should make a spec thread on coils as we have here for rear shocks options???

Thanks to Andries for some coil information.

883 - 17mm x 375mm - 10.6 coils - 5.7kg - 590lb/in
884 - 17mm x 385mm - 10.6 coils - 5.7kg - 590lb/in

897 - 19mm x 390mm - 6.75 coils - 7.2kg - 387lb/in


Stock specs:
Front:
V8 4WD - 16mm x 345mm - 7.75 coils - xxkg -??lb/in

Rear: (Part #48231-35280)
15mm x 360mm - 6 coils - xxkg - approx 180lb/in

Other aftermarket:
Front:
Most coilover use 650 lb/in coils and length doesn't matter as they use adjustable collars.

Rear:
Most seem to make 15-20% firmer coils over stock (AP, DR, SAW) and for 2" of lift on stock weight.

Deaver or Coil Spring Specialties can make to order, but popular rates are 20% for a better ride and 30% for more load capability, these rates are over the stock rate.

Andries, I count coils on my front struts (886). It's 12.5 coils.

Thanks, Alex.

[AlexJet]

Andries, could you put "Sticky" on this thread? In this case if someone need some info, he can get it without searching tons of pages. Thank you.

[bulldog]

This thread is already linked from the suspension FAQ thread. Avoiding too many stickies is normally a good thing in a forum. I update the suspension FAQ thread from time to time with links to newer threads like these with good and interesting info. This way we can avoid many stickies, and just have one thread with links that make sit much easier to search and read the same forum.

[AlexJet]

Best of all is to make a sticky thread with ALL the data, but without discussions, like FJCruiserforum does.

[bulldog]

Yeah I'll update the suspension FAQ a bit later this year. Plenty of new options came in lately. Hopefully more tech info will be available on them as well.

hi,
noob here. i just wanted to give you my experience. I was looking for a minimal lift on my 04 v8 sr5 4r. so we put a set of new oem front and rear coils and bilstein shocks from an 08 fj cruiser off road package, thinking that the FJ set up was slightly stiffer than our stock set up. we got about a 1/4" lift in the front and about 7/8" in the rear. the ride is a bit more planted but not that much. probably due to the offroad bilsteins. we got the fj set up very cheap on fjcruiserforum.com. i hope this helps as i could not find much info on the stock fj coil rates also. p.s. the fj wheels look great on our "new" 4r.
i like the stiffnes of the rear but the front still feels abit soft. we may just put some spacers on the front now to level out the stance, since it is now "worse" than stock.
hope this helps somebody.

by the way. the only info i could find about the 4R coil rates was posted here, so thanks very much. if i can answer anyones questions about install or anything else, pm me.

Was the 4Runner a V8 or V6, 4WD or 2WD?

His is a "04 v8 sr5 4r", mine is the V6 4wd.

"we got about a 1/4" lift in the front " Mclovin, thanks. It sounds like the Bilsteins did you some good and the FJC springs weren't the best for you but helped a little. From other posts it seems as though my V6 is about 200lbs lighter in the front.


I guess I'll put my bottle jack on a scale and lift with about 200lbs and measure then add 1/4". That should give me an idea what the FJC springs will do on my V6.

Mclovin, I have been looking at Cornfed 1" spacers too. That may be exactly what you need to finish up.

If all you want is better shocks and a little lift why not get bilstein 5100 with the adj. collar. you can get a set for 190 delivered and keep you stock springs. But have better shocks. They adjust from stock then +.75 then +1.65 then to 2.5 in of lift its your choice. Just put the snap ring where you want it.

[Mclovin]

sorry, I drive a 2004 v8, 4wd, 4Runner.
I have some 1.25" daystar spacers coming that i will try but i think the 5100 bilsteins may be a better bet since they will provide a little preload on the front coils. the ride has stiffened up on both ends but the rear is definatly more stiff. (not rough at all though). i think some preload on the front would even it out.
I hope this helped.
p.s. you can find fj coils for so cheap on ebay or FJCruiserforums that i think it is worth the experiment. the only drawback is a sore back and some scraped knuckles from the install.

JAM07Sport: thats a good price for the 5100's. where can i find some? thanks

[AlexJet]

Guys, lets keep this thread to specific data and make a new thread for discussion of options and personal opinions.
Thank you.

My FJC Springs are here, finally. Once again, I plan to use the front springs on my ’07 V6 4x4 T4R. I’ll post results when done. Some info that might be nice to add to this thread is as follows:

FJC Front Springs: Approx. 13.8125” tall (351mm) with ≈8.75 coil turns and a diameter of 15.9mm. My stock ones measure 14.9mm diameter, don't know about other dimensions yet. Based on other posts here it looks like a 10mm (≈3/8 of an inch)longer spring with a slightly thicker coil (higher rate).

FJC Rear Springs: Approx. 14.75” tall (375mm) with ≈6.5 coil turns and a diameter of 15.3mm. My stock ones measure 14.6mm diameter, don't know about other dimensions yet. Based on other posts here it looks like a 15mm (≈5/8 of an inch)longer spring with a slightly thicker coil (higher rate).

I stress the APPROXIMATE in my measurements as they were done with a tape measure and a Harbour Freight digital caliper. I did measure 3 times on each with confirming the zero point between measurements.


I am confused My diameter dimensions for my stock T4R springs (currently on the vehicle) are quite different than the ones posted here. I so doubted my measurements and cheap calipers I mic'd the FJC springs and did the math to confirm my results for the FJC springs. I didn't mic my stock T4R springs but I do know I'm very close.

I hope this is of interest

Edit: I have installed them: http://www.toyota120.com/forum/showt...9288#post39288
