Four Link Suspension --

A type of suspension link set up used on solid axle monster trucks and rock crawlers. This uses 4 rods or links to connect the axle to the chassis - the rods prevent the axle from shifting side to side, front to back, and twisting or rotating. The lower links are usually parallel to each other and mount to the outside of the chassis, while the upper links mount inside of the chassis, and may angle inward towards each other at the top (a.k.a. a triangulated link). This tends to be more stable than a 3 link suspension, but may result in reduced articulation. Adjusting the length of the upper or lower links affects how the axle transverses obstacles, much in the same way that adjusting caster affects independent suspension models. Wheelbase is also commonly altered by adjusting the link length.
