????? what dp you mean?

 

Eaisest way put is What is the best way to lower the *** end of the truck.
I was thinking of overslinging the diff and putting air shocks on it.

 

how would u lower the front?

 

I have the set from Lowriders Unlimited Code: DB3006-3 Price: $509.95 description is as follows, a pair of front lowering i-beams that fit 1980-1981 Ford F100/F150,These beams are a 3" drop and come with all required parts to complete the front installation.
This is the eaisest way possible....Thanks for asking
A.J.

 

i am having the same delema with the same truck and year .What i am toying with is a 1989 caprice complete frame.The wheel base is out only 1/2 inch not sure about the tracking or if i will incorporate the 81 FORD frame into the Chevrolette caprice frame just an idea.That way i will not have to cut the frame just graft the ford to the chevy just an idea

 

Have you looked into installing the late model crown vic front crossmember into your truck to lower the front?

The rear of these trucks is standard parallel leafs, and the common methods of lowering them apply. Flipping the axle would probably be the easiest, and I would try it without notching first, and only notch it later if you have interference.

 

I had an 82 stepside that I lowered clear back in high school.

DJM 3" drop beams in the front. But it already sat about 1" lower than stock due to a 460 transplant.

First rendition I torched the old spring hangers off of the rear suspension and bolted up DJM 4" drop pieces. Still was pretty high compared to the front so I put the stock hangers on it and flipped the axle over to the top of the rear leaf springs. Used some brackets I also got from DJM to use the existing leaf spring pads on the axle. Sat about 7" lower than stock. I ran 235/75/15 tires in front and 275/75/15 tires in the rear, it sat really nice.

Here's the part you're asking about the rear axle flip; after it was flipped, I chopped the bump stops about in half and was only left with about 2" of upward travel in the rear suspension. Worked OK with 2 people in it, but if you put any kind of load in the bed, the rear suspension would bottom out on a regular basis.

So the correct way to lower one when flipping the axle to the top of the leaf springs would be to notch the frame rails - but it is still driveable without notching them, as long as you don't use it like a truck.

FWIW, that truck sat really nice, still rode just as smooth as stock, and handled WAY better - even without sway bars. I kick myself every day for getting rid of it....

 

Franklin2. I thought of that so put the word out I CANT FIND ONE OF THOSE ANYWHERE AROUND HERE Kingston East Ontario CANADA as a mater of fact they want more than you guys are paying for the whole front end for just the front crossmember the word must be out lol lol I worked on a tilt caddy telescoping steering wheel and got the ford piece on it for the firwall now all i have to do is switch the wiring

 

Well I went out and tore the front end off of the caprice,then measured everything up the length of the F100 shor-box stepside is 116-1/2 inches.The 89 caprice is 116 inches actuall 115.9 inches the Caprice front end is 61.7 inches center to center of tires the caprice wagon is 64.1.The f100 1981 is 64 center to center i am going to mock this up and see what comes of it
