TAKE THE BUMPS OUT OF THE '80S (AUTOMOBILE SUSPENSIONS)

Noise, vibration, and harshness (NVH) due to downsizing and to the new low rolling resistance tires on 1980 American cars have been reduced through better shock absorbers, improved isolation of suspension members, and specific reinforcements in the body and frame. Shock absorbers have been fitted with pliacell gas springs, low-friction single-lip seals, and teflon banded piston skirts which reduce NVH and improve impact isolation. The most common way to reduce NVH has been to provide good isolation of the suspension members and powertrain from the body by using thick rubber bushings. Computerized structural analysis has been used to optimize the lightweight body and frame design that complements the entire NVH isolation effort. New with the 1980 models is the use of an independent front suspension on four-wheel drive vehicles; this allows for a much smoother ride.
