How can you tell when you need new leaf spring? And is the spring rate located at.

 

stand behind your rear bumper,bend down and look at the leafspring longways, if its pretty flat you need a new one. check your doorjam sticker and decode the spring code...

 

^^YUp....I'll add that if it appears to be shaped like an " S ", they need replacing.



Spring rates can be found on your driverside door sticker, under the SPR. 1st digit(or 1st and 2nd) will be front springs, 2nd(or 3rd and 4th). Some codes are 4 digit, some are 2. 11KK BBCC 1K BC...like that. That's the ford letter/number spring rating system...idk how to find the actual numerical weight rating.

 

Thanks..looks like I need new leafs then. LOL
Would that be causing a ruff ride? If fells like the back half is jumping in the air everytime I go over bumps. And i just replaced the shocks so I dont think it would be that.

 

Im going to run to the junkyard tomarrow. What other leafs fit our trucks with no modification.

Just ran out side and check the are the bk ones.

 

Your T-bars are B bars. Your leafs are K leafs. You've got midgrade bars and midgrade leafs(or is it leaves?). You can bump the rear leaf up to a C leaf which is standard on trucks with the Class 3 tow package.


Anything Ranger will do. Find some lower mile ones. You can also run Explorer leafs too to get you approx 2" or so of lift.

 

I know their is a sport trac sitting in the junk yard. Not sure on the miles it has. And that would be straight up bolt on.

Thanks shane, I think I owe u beer for all the help. lol

 

hahahaha.


Get them trac springs and ditch your block, get some new shorter Ubolts, and you'll be golden my friend. Truck should drive better too.

 

Yeah I think im going to get the AAL and shackles like we talked a while back and dich the blocks.

 

get the explorer leaf spring and shackles.

 

Downey when you did yours did you ditch the rear blocks??

 

Just got back from the junk yard. The sport trac had about 150,000 miles on it, and they want $50 for one pair. Im looking at car part.com right now.

Is the 4 leaf better??

 

ya when they look like mine they need to be replaced!!! haha, one side of mine are straight plus a broken leaf in the spring and the other is fine.. a guy i know runs the local school autobody shop and he has a 93-94 ranger thats lifted, not quite as big as beard's but i'd say about 3/4 of his. and he's running chevy springs in it, you can run just about anything as long as its similar to the ones u got now. measure them, exploder leaves will work too.

 

I have a pair of 'C' leaf springs that have about 8,000 miles on them I could sell you if you need them. PM me if you are interested.

 

pm sent

 

what happens if you dont ditch the block? would it just lift it that much?

 

It will lift it 1.5 in I think, Maybe 2 not sure.

 

Any idea what the spring rate of the Expo leafs compare to the Ranger leafs? These sound perfect for rear flip, only 3-4" of drop vs. the 5-6" with Ranger "leafs/leaves" . . .

 

i realize this is an old post. but im in the same boat right now i wanna get some explorer leaf packs. if so can i remove my blocks and keep the same ride height or keep the blocks?

 

explorer leaves and ditch the block be about the same as stock

 

thena lock, in a sock, from Captain Spock

 

so it will keep it stock height in the back if i ditch the block for sure?

 

Where is the best place to buy them? I'm sick of dealing with the junkyards.

And which year explorer springs work the best? Sport trac?

Anybody have any part numbers?

 

Junkyard would be your best bet on finding them chep. You could get them for the stealership if you want to spend close to 300 plus per side. I bought both mine for $100.

Whats your area code?

 

Actually I just checked on a couple ford parts websites and they're around 120 bucks a side. Shipping shouldn't be too bad. 40-50 bucks a pair.

area code is 812

I need new torsion bars too. I might just say screw it and upgrade everything all at once.
