link/coil, coilovers, or
I know, you want to
know more about coilovers. But, we have to start
with the basics.
Leaf springs: This is the
simplest form of suspension for under your rig. No special parts required. Leaf
springs are reliable, easily accessible, simplistic in design, and readily
available. All that is required is a set of stationary mounts, and a set of
pivoting mounts. The stationary mounts hold the springs in their prospective
area, while the pivot mounts allow for the spring to compress. If pivoting
mounts are not installed, the stress can rip the frame rail. This exertion of
stress on the frame is what makes this type undesireable. Leaf springs transfer
all stress from the road, to the frame. Another fall back, is that they do not
flex like some of the other alternatives. They are limited by the length of the
spring, length of the shackle, number of leaves, and spring rate.
Link/Coil: This form is by
far not the simplest, however, but articulation becomes apparent. This
particular set-up requires four points on the axle, four points on the frame,
and four bars to correspond to the mounts. This needs two mounts on the top of
the axle, two on the bottom, and the bars to run from axle mount to frame
mount. This is critical, that the bars must be precise. Although, with proper
measurements this can save money. Coil springs are far cheaper than coilover
shocks. This set-up is far friendlier for daily drivers. There is minimal axle
wrap, a smoother ride, a consistant pinion angle, and (with a panhard bar)
stable lateral track. The road stress is not on the frame with this arrangement.
But, it is on the coil itself.
Coilovers: This is the holy
grail of buildups. This form is extremely difficult, yet simple. It is similar
to the link/coil set-up, but with a few minor differences. This can be built
like a 2 link. This is in part due to the shock being inside the coil. This has
the most articulation, and has many benefits. If your entire suspension is built
using solid axles, coilovers, and minimal links. Then, your ride height is
estabolished using the coil spring and shocks combined length. The longer the
coilover, the greater the ride height. The greatest complication, is that road
stress is not absorbed by the frame or coil. The heavier impacts are absorbed by
a mount that consists of a bolt. This mount is merely a shock
