"PROS vs. CONS
SUA vs. SOA
Let the debate begin!
The following are my personal observations having driven my Scout in various forms since 1998 and various lifts from none, to 4" SUA to SOA.
RIDE:
My worn out stock springs = BAD
My new 4" Skyjackers with all new bushings = Good
My SOA on stock springs = OK
LIFT:
Stock = BAD 0"
4" Skyjackers = Good initially, but the rear sagged in a year or so, the front was solid the whole time. 3.5"-4"
SOA = Not as 'good' as it was promoted, but remained solid for years. 4"-5"
HANDLING:
Stock = OK
4" Skyjacker = Fine
SOA = OK, the increased caster angle did help general handling.
(This category is really hard as other factors changed at the same time and it is unfair to compare handling across the board...)
STEERING:
Stock = OK
4" Skyjacker = OK, pretty much the same as stock.
SOA (With conversion to high steer) = EXCELLENT, drives like a modern truck even with worn out components and large tires.
OFF ROAD ABILITY:
Stock = Good! (These are Scouts we are talking about)
4" Skyjackers = Great - the rear flexed great, the front was stiff but worked fine and the lift really improved tire size choices, which improved off roading.
SOA = BEST! FLex all around was greatly improved, lift and tire clearance was better.
BREAKAGE:
Stock = BEST!
4" Skyjackers = Good - I did have trouble inverting shackles with the lift springs. I also had increased axle wrap in the rear.
SOA = WORST - I have bent the soft stock springs, rear axle wrap is increased, I have bent front springs, torn spring mounts off, etc. With the use of stock springs in the SOA you are really testing the strength of a spring designed for SUA and the newest stock springs are 26 years old... Using 'new' stock springs would help, as well as building a rear anti-wrap/traction bar.
SUM TOTAL:
Stock = OK - if you like lil' tires
4" SUA Lift = Great - Dead simple, easy and strong.
SOA = Good/Bad/Ugly - If I didn't need the lift I'd still be running my Skyjackers
