The Chevrolet R20 Suburban is a rear-wheel-drive, 3/4-ton SUV that was part of the third-generation Suburban lineup, noted for its balance of work-ready strength and passenger space. The 19-year enduring bodywork design of this generation made it famous for both durability and practicality. A 250 inline-six and two V8 engine options entered the market at the beginning of 1973 to accommodate varied customer performance requirements. The engine range reduced to the 350 motor only after 1980 and developers started offering diesel engines in export markets. Although the NP208 transfer case replaced the NP205 in some 4WD models like the V20, the Chevrolet R20 Suburban, being rear-wheel drive, did not use a transfer case. During the Chevrolet R20 Suburban's release the Eaton automatic limited-slip differential introduced better control and grip functions specifically in difficult surfaces. Convenience features included dual-zone air conditioning and a spacious rear cargo area, along with a low step-in height for easier access. When conducting maintenance or repairs you should use only Chevrolet R20 Suburban genuine parts because they pass the company's exacting quality standards which leads to better longevity and optimal vehicle performance levels.
