In regards to Downey's & All Pro's coils. Does the lift (1.5”) measurements start from the a$$ sag or stock.

With a$$ sag my 4Runner measures: 11.5" fender to top of rim

I think stock is: 14.5" fender to top of rim

If I added Downey's or All Pro's 1.5” coils would that bring my 4Runner to 13” or 16” fender to top of rim?

 

i think that it is 1.5" over factory spec, not sag

 

if its a 1.5" lift it will lift whatever you are currently at 1.5"

 

You’d think they’d have some sort of scale.


This is driving me nuts I don’t know what to go with, 1.5” Downey/All Pro or 3.5” FJ80 Short Side Coils? I guess I’ll have to email All Pro and ask. Why didn’t I think of that sooner ?

 

they do have some sort of scale... its called inches!

a 1.5" lift will provide 1.5" of lift.... never have i seen 1.5=3.5

 

What I mean is a start measurement. Not all 4Runners are going to sag the same. Some may sag 12” fender to rim and some may sag less or more.

The 3.5” is for the FJ80 short side coils, I was not saying 1.5”=3.5”.

 

You still don't understand... Springs can sag over time and with varied use, they don't call you up, ask how far your springs have sagged and then call the manufacturer to make a special spring to be exactly 1.5" taller than your specific spring.

To answer the original question, my Downey 1.5" HD springs put my rear wheel/fender measurement at approximately 14". It looks right (level) with similar wheel well gaps (~14") all around, I don't have cranked Tbars either.

 

Thank you firemedic.

So basically 1.5” Downey/All Pro coils are just stock coils. The 1.5” just brings you back to stock ride height.

 

Pretty much, but the HD (heavy duty) coils, which are the ones commonly referred to on this forum, supposedly have a higher (stiffer) spring rate than stock, for better cargo capacity/handling.

 

Generally speaking the 1.5HD will bring you a little over stock. Mine ended up about 0.5" ass end higher than the front - which looked just fine. That was enough of an excuse to crank up the front 0.5" to level it out though.

Some folks have reported more and less of a lift over the original stock height but over all you should end up somewhere close to 14.5" from the top of the wheel to the bottom of the fender

 

My 1.5s gave me 2" at the wheel well. It is in fact a 1.5" lift over factory.

 

Not Exactly, if you have a lot of sag, expect to see 2.25" of lift in the rear after install.

 

Cool, thanks.

So with 1.5” coils I’d be less or around stock height, my rear sags 3" under stock (front = 14.5). That answers my question. I’m going with FJ80 short side coils. I’ve read they give around 3.5”.

 

Only thing there is I am not sure if these 2nd gens were ever level from the factory. The 1.5" will lift you over showroom stock for sure but it is not that radical. I just dont know if anybody ever recorded what the showroom stock height was with fresh springs. The Downey 1.5"HD coils are actually the same height as the factory coils when compared in an uncompressed state...its the spring rate and thickness that gives you a 'lift'.

I am running 30x9.50x15 with 1.5"HD and its just fine - but room for plenty more thats for sure (although @ 2.25+/gal and rising I'm more likely to go back to 225's )

Bottom line is the 1.5" springs should get you up around 14-15" above the top of the rim no matter where you are now. If your front is currently 14.5" then the 1.5" coils will at least level you out or give you a slight ass end high rake but it wont be radical. If you go with 3"+ coils you will be back here real soon asking about raising the IFS 3"....

 

The OME 901HD in fact will raise it 1.5" over Factory Stock Springs. In my Avatar you can see my '91 with OME901HD springs and 33's on it. Here is the kits we sell.

Mine has Option 2 and the picture makes it look like it still sags but it is level.
Hope this helps....................

 

I'm looking to fit 33x12.50's under it. I've got the front figured out. I just couldn't figure out how the 1.5" lift worked.

Thanks,

 

I'd like to use Rancho RS9000X Shocks. How much for just the BJ spacer and the coils shipped to 30534?

Do you have any larger pictures you could post of your rig?

 

Ive used downey and allpro. They are 1.5in over stock height since the component of your suspensions that has caused the sag is the spring and you are replacing the spring so its 1.5 over stock. if you are sagging two inches you get 3.5 in lift.
and buy the way the allpro coils are 100000000x better than the downeys.
The downeys rode like crap and were really tippy.

 

I think you'll find the 13.5"-14" rim to fender is the stock front measurement. The rear will be less, since the rear wheel wells are not cut as high up as the front. This is part of what makes the sagging look worse than it really is. To measure level, go from the ground up to the frame at two points along the flat part and then adjust the difference in height for the separation distance compared to the wheelbase. For example, if you find the rear height is 1/2" less than up front and you are measuring 2 points 51.5" apart (wheel base of 103"), double the 1/2" height difference to get a 1" sag in the rear.

 

The SDORI BJ spacers are $99.00a pair
The OME 901 HD Coils are $58.82 each
$20.00 Freight to your Zip code.
