Overs can be ordered with the following coils: 600, 650 or 700. These
numbers are how much weight it takes to compress the coil 1 inch. 600 is
typically for a stock truck and 650 a truck with a winch and bumper.

an aftermarket UCA. We recommend the Camburg Ball Joint Arms or Light
Racing Arms - the new cast version.
In 2012 we bought a brand New Trail 4Runner with KDSS. While the bulk of or work
at that time was with 3rd gen 4Runners (1996-2002), I knew this was one heck of
a truck and spent years dreaming up parts to make it better. After installing
our current offering and other manufactures suspension offering for these
trucks, there was one thing that I felt everyone dropped the ball on.
The Trac/PanHard bar for the KDSS trucks. We all know that the Jeep Wrangler and
the American full size pickups with straight front axles had Trac/PanHard bends
in them to dodge around things for many years. These bars are all sand cast and
difficult to manufacture on small scale, which the KDSS market it.
After working on this for literally years we found a solution. The original
prototype was fabricated out of cut tube and zigzagged all over the place. It
was incredibly time consuming to make and frankly looked ugly. But at that point
we had a pattern that cleared everything. Full stuff with coils and shocks
removed and full drop with shock removed. We now knew exactly how far the KDSS
bar would let the suspension move, uninhibited bay the trac bar.
So finally how do we actually make this thing? Waterjet is how. Starting with a
3 foot by 3.5" of Cold Rolled Solid Steel Bar, the Waterjet carves this bar out
of solid 1" thick cold rolled steel! The entire bar is a consistent 1" x 1"
solid cold rolled steel. It is heavy. On the 4th gen 4Runner, Toyota used 1"
round solid hot rolled round stock. So this is not a new idea with the size and
material used in this application. The ends are custom polyurethane bushings
made for us by Daystar in Phoenix. They have grease grooves and we have made
several improvements to the mold over the last 8 years (2010-2018) as we have
always made a straight tube Trac/PanHard bar for the 4th/5th Gen 4Runners and
the FJC. The adjustable end is a huge 7/8"-16 grade 8 threaded rod into a tube
adapter made by Ballistic Fab in Tucson, hollow end of the bar is 1.5" x 1.5" x
.120 wall Cold Rolled Square Tube, finally the same bushing setup as the other
end. Finally the part is painted with STEEL-IT® super corrosion resistant paint.
The rear shocks are custom made by Radlo just for us and are designed to retain the stock compressed length/upward travel. So no up travel is lost. What they have done is add additional droop to allow the hydraulic plunger to drop an additional 1" downward. This leaves an additional 3/8" plunger travel still, so no damage will occur to the unit. These shocks WILL NOT pull your plunger out too far. They utilize the maximum up travel provided by Toyota and the extra down travel provided by our custom Trac/PanHard bar for the ultimate KDSS articulation. You MUST use stock Toyota upper and lower rear links or aftermarket upper and lower rear links that are set to the same length as the stock Toyota rear links for this product to work correctly. It does not matter if they are stock or aftermarket, it only matters that the length of the links is the same as stock.
