I've always been disappointed by how stupidly easy my 87 F150 2wd squats. I swear an empty Solo cup will make it sit level. So, I had a thought...in the local Pull-A-Part, there's a "mint" (just put there) 97 F250HD Super Cab shortbed 2wd with a 460...it was a state truck, I'm not even sure how it got damaged...something crushed the COWL...not the roof...not the hood. The cowl, windshield and dashboard.
So I thought about stripping all the suspension out of it, rear axle, springs, beams, everything and putting it under my 87 F150 rclb 2wd...is this pretty much a bolt-in swap like I'm thinking? I'd love to make it more heavy duty...straight 6 and all...
Not just springs. Everything but the frame. Then my weak links will be the frame and the SROD transmission...my list of items to get...
1. Rear axle
2. Rear springs/hardware
3. Front beams/hardware
4. Front springs/hardware
5. Front spindles/brake calipers/rotors
6. Possibly brake booster/MC/proportioning valve
7. F250 badges off an 87-91 era truck if I can find them...heheh.
I may never need that much capacity, but doing all that is like carrying a condom...it's better to have it and not need it then need it and not have it.
Yea, the front suspension was my concern. I'm not gonna add the 3/4 ton springs without the rear axle (it'd be like putting splayed main caps on a Yugo engine) and I'm not swapping the rear axle without the front setup...two sets of wheels would be stupid as my ex-wife.
Upgrade all that stuff and it still doesn't change the truck's GVWR, so you still can't legally carry any more weight. Sounds like your springs are just old and worn out. Just get yourself a NEW set of 5 leaf springs. Some F-150s came with 4 leaf springs and some had 5. The ones with 5 leaves are the same ones in an F-250 anyway.
Eh, I suppose if I can't swap it I'll just keep the "truck" around as a driver...and find a real truck for work. The point was to upgrade the truck I have...but I understand if it's not possible/not really feasible. I just really like HD trucks...and seeing this 1/2 ton squat when I stand on the tailgate (I'm 173 lbs) just annoys me and screams "weak"...
2wd f250s do not have front leaf springs, they have coils, just like f150s
Also 2wd F150s have 2.5" rear leaf springs, F250s and up have 3" slings, so you would need to change the riveted on hangers too.
Like others have said, just put a NEW set of F150 springs in(get the heavier ones) and it will be a super improvement
