| A 4 link provides control of the axle during suspension cycling
and to locate the axle under the vehicle. The most common 4 link is used
with panhard bar. This is found in many cars and pickup trucks. The 4 link
for a solid axle has a few variations such as the triangulated 4 link and
the Parallel 4 link. Typically each arm has a spherical joint or rubber
bushing at each end. Consequently they react to loads along their own length,
in tension and compression, but not in bending. In a solid axle suspension
the upper arms may have an angle of at least 45 degrees between them, to
prevent the axle from moving from side to side while allowing the axle to
articulate and move freely up and down. In a solid axle the lower arms control
forward and backward motion, the upper arms control forward and backward
rotation. This rotation is present under acceleration and braking. Kit includes
bars, brackets, coil-over crossmember. Coil-over 4-Link rear suspension
provides the best ride for any classic truck. These kits attach directly
to the stock frame rails. The adjustable axle brackets let you set ride
height in one of three positions. A bolt-in upper crossmember for coil-overs
is included. |
