- Relating to upgraded variations of full-size vehicles, Chevrolet’s Silverado ZR2 Bison is particular in its personal manner.
- We’ll present you across the Bison package deal, which has the identical suspension because the common ZR2.

The Chevrolet Silverado ZR2 Bison might lack the high-output bragging rights of the Ram TRX or the long-travel wide-track suspension of the Ford F-150 Raptor, nevertheless it has a number of options of its personal. For starters, it is cheaper than these two vehicles, and it gives a locking entrance differential and Multimatic DSSV spool-valve dampers. On this video, resident suspension knowledgeable Dan Edmunds explains how the ZR2’s suspension works and reveals how a lot it flexes in comparison with different vehicles with the Ramp Journey Index check.
The Silverado ZR2 on this video has the Bison package deal, which provides high-clearance bumpers and underbody safety together with completely different wheels and inside options however leaves the truck mechanically unchanged in any other case. As a result of the suspension is identical, the findings on this video apply to the usual ZR2 as properly.
We begin on the entrance, the place the Multimatic DSSV dampers seem prominently. The spool valves contained in the shocks supply larger management however, as Dan reveals by turning the wheels to 1 facet, the three-chamber design takes up valuable house.
After weighing a mounted wheel and tire, Dan switches to the rear suspension, which options inverted Multimatic dampers and blocks below the leaf springs to attain its carry.

It is greater than the equally priced and outfitted Toyota Tundra TRD Professional (408) however decrease than vehicles with broad monitor long-travel suspension, such because the last-generation Colorado ZR2 Bison (501) and F-150 Raptor (559).
