The FailRated '85 Longbed Build Thread

As you can see my stock rear leaf packs sucked balls...

...so I got some 58" 97-03 F150 rear springs
Front spring eye to center pin is 26"
Rear spring eye to center pin is 31.75"




The front spring hanger had to be moved forward 5.5"

I'm temporarily running a dual shackle setup until the new shackle hangers arrive this week. The F150 shackles fit nicely into the stock toyota shackles with new toyota bushings installed in them. The terrible shackle angle is probably causing me to lose an inch of ride height.

A shot of the pack with 2" block. Once I get the shackles setup properly I should be able to step down to a one inch block or no block. You can see the one unpainted leaf I removed initially is reinstalled here.

What it looked like with the third leaf removed with 2" block. A little low in my opinion so I put the leaf back in which raised the rear 1-1.5"

Current ride height measurement for reference. With the dual shackles this measurement is 17" at full droop.

So I've had a jingling/groaning sound during deceleration above 45 MPH for a while now. When I drove the truck sitting low in the rear for a day the sound was gone completely. After I threw the leaf back in and raised the rear up to where I like it, the sound came back. I'm assuming my drive shaft angle is to blame. I have the ujoints at opposite angels like you're supposed to if you're not using a double cardan. So my question is I have an extra front driveshaft with a double cardan and an extra rear driveshaft from a manual trans truck that's about 2" too long. Do you all think I can have a drive shaft shop put the double cardan from a front shaft on my extra rear shaft and fix this problem? Is that a good/bad idea?

Look for blocks with built in degree , or if your blocks are steel look for some steel degree shims and weld to the blocks to get your driveline angle correct.
Rusted is correct. To properly run a double cv your rear pinion should point @ transfercase flange.
Truck looks great & looks like it wheels too.
