Skyjacker suspension kits are among
the highest overall quality you'll find for the Ranger/Explorer/Bronco II. Unfortunately,
they aren't without a few small issues.
Here is the coilspacer installation on a Supercab w/Dana35 axle
The spacer (along with any 1-3/8" I.D. washers needed) goes under the bottom coilspring perch (washers first) which is on the top stud/bolt attaching the radius arm to the axle. Be sure these bolts are torqued to 200-250 ft-lbs (the coil retaining nut only needs about 75). It is also possible in some cases to use the next size up coilspring and do away with using a spacer completely. Skyjacker pt.# 136 coils (spec'd at 6" lift) produce 4.5" lift on a 4.0V6 Supercab 4X4 and work well with the axle mounted on the 4" bracket position (upper holes). The steering linkage angle will be better with the axle in the upper holes as well.
A second item is the overload leaf on the rear leaf springs that usually gets crooked. Threading 2 nuts with a flat washer between them down the rear U-bolts and tightening them together alongside the leaf will keep it inline. The leaf will then butt up against the edge of the washer keeping it straight. I have found trying to use the OE retainer on the Skyjacker leaf to not work. The small tabs tend to give way.
A third item is with the Skyjacker DOT braided brakelines. The banjo fitting that attaches to the brake caliper needs a bit of grinding (or filing) at a 45 degree angle on one corner. This will allow you to put it in a better position (less vulnerable to rubbing on the tire, and allows for more suspension travel). In addition, the brakeline should be secured to the coil winding with a zip-tie to help keep it away from the tire, as well.
Often some grinding on the backside of the
driver side axle beam at and around the support bolt for the diff is needed to get the
radius arm of a Class II kit to fully seat forward so you can get the main bolts through.
The radius arm itself may also need grinding on the flat area between the axle mounting
ears. This one is not exclusive to Skyjacker. I've seen this clearance issue at the diff a
few times with different kits. It may be due to manufacturing tolerance variations at
Ford. This will most likely be needed on the Dana35 axle. Dana28 axles probably
won't have this issue.
Lastly, I have found the replacement
transmission crossmember supplied with the Class II kits is of somewhat thin tubing.
Although it is plenty strong to support the transmission, a good impact, high-centering it
on a large rock can dent or bend it.
