No you cannot use the 6" skyjacker coils on an 07. That is for the 93-97 years with a different suspension. The most lift you can get from coils on your a-arm ranger is 3" but you will need new upper arms to correct the balljoint angle. People have been able to just put in 2" lift coils and still align it, however, you will go through balljoints incredibly fast.
Also, with just the spindle lift you dont need new shocks for the front. You will need new ones for the rear. If you get a coil lift you will need new shocks for the front (only for the amount the coils lift, not the spindles). If you get the coil lift and want 5100s, I can give you the part number that will work.
