Wanted: Coil Spring Measurements When Installed (Stock & Lifted)

[4x4junkie]

'85 std cab longbox, 5.0, M5ODR2, NP205 (heavy), fiberglass topper and full tank of gas. 10 year old stock replacement springs for a 91-94 4dr Explorer from Carquest. Around 9-3/4" to 9-7/8".

That looks like it might be closer to 10.5" to me... (you need to measure from each end of the spring).

I have nothing on why people said the F-150 springs felt stiffer, only thing I can come up with is psychological (people thinking "oh it's for a heavier truck so it MUST be stiffer"). A spring having a lower spring rate will be softer than one having a higher rate. Simple physics.

Or, maybe more of Moog's specs are wrong... I don't know.

Years ago I had saved this pic off the internet, I recall it was taken from Fourwheeler or maybe Peterson's 4Wheel magazine. Maybe it can be useful here

Doh.

I have it drove into the garage getting ready to swap the rear springs so I was doing all this while almost doing a headstand. I didn’t thing about that bottom coil, I probably couldn’t even see it from where I was.

I will have to try again...

I'm still looking for the installed coil spring measurements of James Duff, Rough Country, and Superlift lift kits.

After installing Skyjacker 1.5-2" lift springs the measurement is now 12" versus the 10 3/4" with the original springs. 1992 Ex Cab, 5.0, 4x4,full size truck 5 speed, NP205 TC, 3" body lift.

1989 ranger stx single cab, 4x4 manual. quite possibly original springs. 9.5-9.75 inches, i think its 9.75, but was kinda hard to measure where it was sitting.
i only just saw this post and im new to the forum, so i have a good excuse for not posting sooner.

Stock springs: 10 3/4" 1992 Extended Cab, 5.0, stock bumpers, no suspension lift, 3" BL, full size truck M5ODR2 trans., NP205 TC and I'm putting Skyjacker 132s on it this weekend.

are you putting 132's?" or 132x's? and i cant find a difference between the two... but please let me know what you decide to do on that, im looking to put about 2-3 inches lift on my ranger, and would appreciate the info.

Here's the difference between the Skyjacker 132 and 132X springs.

I'll put any aftermarket spring measurement on the list that I get.

so it looks like the 132's are for 2wd's and 4cyl? by this logic the 132x is a for a heavier load.

I called skyjacker this morning the representative told me that the 132 is 14 5/16" long with a ppi of 445 and the 132x is 15.5" with a ppi of 397
