Agreed reduction of A is a large gain. in this old dodges case loss will occur apon repars being made . Ill explain . This model of dodge uses an aproxamitly 3" tall 0 rete spring rubber for proper ride hight. Theas last (from what I've read) aproxamitly 100,000 mi 10-15 years. My truck on the original rubbers @275,000 and 25years the rubber is about as thick as a pice of paper. = ~ 3"lowerd in the front. Stock rear /~ 17" under the hitch. So whin i get this defect repaired the A will grow.

If the Montana roads and 4-8"ice ruts hadn't taken out 3 Ball joints in 6 months, I would not be considering raising the front end. Cause and effect. I think the Ball joints are operating out side an accepted operating angle causing failure.at a price of $100.00 ea upper and 75.00usd ea lower purchased yesterday will in stall in near future. With theas NASCAR spring rubber less the splits ABA testing will be labor intensive but valid. I will have to do a life span test to determine. If the accelerated Ball joint wear is worth the extra FE of the lowered front
I would rather keep it low and find some geometry corrected control arms . Then 4 link and bag the rear for load compassity.
Point#3
Appearances can be deceiving.
Some of my design requirements to call a truck a truck it must maintain the ability to:
1 haul 1 cord (4'×4'×8' neatly stacked) fire wood, wet/green Oak ~ 3,000lbs . (This will fit under the cap as in the wrapped load pic the top duse not nee to tuch to bed this load travaled 800 mi with no trouble at 69-75mph)
2 have at least a class 3hitch with a min of 10,000lbs WD
.
If theas 2 are not true itis not a truck, then its a glorified car and the mod isnt practical.
Hence all modds must pass this litmans test
For my cap
easy and quick removal by 1 person (v1.2 =35lbsV1.0=21lbs sub 5min removal, it takes longer to tie it down than to r&r the cap, with my current cap. Note: it duse help to point the truck straight into the wind for installation as the windvaine effect can be strong
Point 4
Allready discussed my method of lowering .. more details to solve this lost compassity. Add some ride hight controls mechanical lenkage or go high-tech decade old tec magnetic, these are both load compensateing .
Eg of a random load that found its way to my truck to day

Moons would help .
Larger mirrors are already wanted . For towing safety.

Sealing off the cab i finally spent the $3 on pool noodles on tusday on Wednesday I got a personal best on my 200mi mpg test route 29.3south and 27.26north an aproxamitly 1.5mpg improvementin each direction . I have wanted to rebuild the headache rack when I first built it (I should have measured twice and welded once .to close the gap to .5-.325" .
Nice truck .
Like they say no pic no happen so
