Because CALMAX Control Arms are made with very specific purposes in mind, we
design arms to work with factory springs and build CALMAX Control Arms to work
with engineered lowering coils. For example, we have designed two different
CALMAX 2” arms for the same application, one to work with the factory spring,
and one to work with a 2” lowering coil to achieve a 4” drop with optimized
alignment, ball joint angles, shock length, and more suspension travel than a
spring/spindle combination. CALMAX Control Arm Systems allow DJM to make very
custom suspension kits for almost every truck and suv on the market today. No
other suspension line can make these claims, for good reason!

| | While control arms might be considered the horizontal members of the front end,
spindles would be the vertical member that ties the control arms together.
Both upper and lower control arms attach themselves through ball joints to
the spindle. This is a cast iron part where the machined “axle” or steering
knuckle is located. The wheel bearings and brake rotors are mounted to the axle,
and the spindle also locates the brake caliper and tie rod end
(steering). Dropped spindles are simply
spindle castings where the axle (or hub center) is moved up away from the lower
ball joint. This lowers your truck by moving your wheel up in the fender well. |  |
| | In 1965 Ford introduced their “Twin I Beam” suspension, a simple, rugged
suspension consisting of a pair of cast beams in the rough in the shape of an I.
Looking like a steel I beam found in building construction, the factory beams
are cast ductile iron and machined just like spindles. This makes them precise
and repeatable, every beam machined exactly the same. So what are Dream Beams? Dream Beams are
tubular in design, using thick walled DOM (seamless) tubing which is
telescoping/nested (tubing slips inside of each other) and does not suffer from
“weld creep”. Dream Beams are welded in a radial manner (mostly in the fixture)
which almost eliminates any twisting or movement of the steel as its being
welded. |  |
| | About the same time that dropped spindles came along, engineered lower coil
springs hit the market place and are used every day by enthusiasts to get the
stance they want. Used by themselves you can get up to 3" of drop or combine
them with a spindle or control arm you can get more. Remember though, dropped
springs cause you to lose travel (ride quality), always have a higher spring
rate (ride quality) and require different shocks |  |
| The lowering torsion bar key works by changing the “indexing” of the bar,
rotating the hexagon shaped mount. When your truck is setting still, there is a
certain amount of weight being held up by the torsion bar. This weight or load
is a designed amount and dictates how high your truck sets. The lowering torsion
bar key by rotating the “index” (hex shaped mount) causes that designed “load”
to occur at a lower ride height, while everything else stays the same. |  | | | |
