Not sure if those are Ranger specific to be honest. They are advertised as a lowering solution for the pick up market here Chevrolet Ford Toyota etc along with some other pictures but yu get the general idea .
From what I can gather all the Rangers in US market are axle under spring setup...
This is the front shock adjustable height kit for the Ranger. It's a simple add on or i should say slip on to your original front shock. This will lower the front end Upto 3 inches
Not my trucks, but I might also need to lower mine yet.
The rear easy, flip the axle
The front end on all of the US trucks looks to use the same shock as the Hi Rider trucks here in Thailand.
The shocks have a 3 inch extension on the bottom of it.
I'll try and post pics of the differences...
