Somebody would be. Post them.@Jim Oaks are you interested in the belltech lowering springs height with a 5.0 in the truck?
Yes.Is that measuring 11 inches on the 2wd and 10 inches on the 4wd?
Nice compilationSo here's some coil spring specs thanks to Moog:
Ranger:
Accoring to Moog, a 1996 Ford Ranger extended cab 4.0l 4x4 has a coil spring that is 11.5-inches installed, and 13.47 inches free. 485 spring rate / 899 load rate.
The standard cab version has a coil spring that is 10.5-inches installed, and 13.75 inches free. 430 spring rate / 1,447 load rate (also comes as 377 spring rate / 1,323 load rate)
The 2wd standard cab short bed 4.0 has a coil that's 10.5-inches installed, and 13.75-inches free. 430 spring rate / 1,447 load rate.
The 2wd standard cab long bed 4.0 has a coil that's 10.5-inches installed, and 13.94-inches free. 489 spring rate / 1,650 load rate.
The Skyjacker 6-inch coils are 18.875-inches free, and have a 435 spring rate.
@ericbphoto has a Skyjacker 6-inch lift on his 1993 standard cab Ranger, and he's measuring 16.50-inches. That means he has a true 6-inches of lift.
@4x4junkie has a skyjacker 6-inch lift on his 1994 standard cab Ranger, and he's measuring 14.8-inches. That means he has 4.075-inches of lift.
@Kona has a Skyjacker 6-inch lift on his 1991 Ranger, and is measuring 14.50-inches . That means he has a 4-inch lift.
Myself, 4x4junkie, and Kona all have extended cabs with heavier bumpers, and winches. Do the bumpers and winches really cause the 435 spring rate springs to droop 2-inches, or have they sagged over time from the added weight?
If I have coils that were 13.75-inches free, the Skyjacker coils should supply my Ranger with a 5.405-inch lift. They only give me 4-inches of lift (14.50 inches installed).
Oh ya.....,Spring Rate is the amount of weight required to deflect a spring one-inch, making it a measure of softness for the spring.Load Rate is the amount of weight a spring is designed to carry at a certain ride height, making it an engineering consideration.
F-150:
1986-1996 Ford F-150 4x4 coil springs are 13-inches when installed, and 16.38-inches free. 366 spring rate / 1,230 & 1,428 load rates.
1979 Ford F-150 regular cab 4x4 coil springs are 13-inches when installed, and 18.25-inches free. 271 spring rate / 1,575 load rate.
The TTB F-150 coil springs should give a Ranger a 2.63-inch lift.The solid axle F-150 coil springs should provide a 4.50 inch lift.
Bronco:
The 1986 Bronco 4x4 coil springs are 12.125-inches when installed, and 16.18-inches free. 366 spring rate.
Econoline Van:
The 1975-1987 Ford E-250/350 coil springs are 15-inches when installed and 18.88-inches free. 420 spring rate / 1,650 load rate. This spring should give my Ranger 5.13-inches of lift, and is slightly softer than the Skyjacker 6-inch coil (Skyjacker 6-inch coils are 18.875-inches, and have a 435 spring rate)
The 1978-1991 Ford E-350 coil springs are 16-inches when installed and 19.27-inches free. 549 spring rate / 1,797 load rate. This spring should give my Ranger 5.33-inches of lift, and is stiffer than the stock spring due to the 64 ppi spring rate difference.
What Does This Mean:
I have no freaking idea.
Actually, my biggest question is what affect the Load Rate has on any of this. People have said that the F-150 coils were stiffer, but they have a lower Spring Rate than the Ranger coil. AND, the F-150 has a 1,230 & 1,428 load rate versus the Ranger standard cab 1,447 load rate.
Reminder:
Spring Rate is the amount of weight required to deflect a spring one-inch, making it a measure of softness for the spring.Load Rate is the amount of weight a spring is designed to carry at a certain ride height, making it an engineering consideration.New Coils or Spacer?
Skyjacker doesn't offer 8-inch coils anymore. Replacing these coils with a new set of Skyjacker 6-inch coils is just going has the same result over time. The 1977-1987 Ford E-250/350 coil springs should give me a 5.13-inch lift, but has a softer 420 spring rate over the stock extended cabs 485 spring rate. Their even softer than the Skyjackers 435 spring rate. They're $77 for a pair at Rock Auto. Skykacker 6-inch springs are $195.
The 1978-1991 Ford E-350 coil springs should give me 5.33-inches of lift, but have a higher 549 spring rate.
There's also an idea of 2-inch Skyjacker lift springs for an F-150 that should provide 5-6 inches of lift, but they're $165.00
It could be just less leverage on the f150 springsI found the specs on the Econoline Springs interesting. I was hoping @bobbywalter would chime in. For some reason I think he's used them before, or has more info about them.
Something that puzzles me about all of these different springs is the spring rates and load rates between the Ranger and F-150. People have said that the F-150 coils ride much firmer in a Ranger, but their spring rate and load rates don't seem to be that much different.
