The Chevrolet R2500 Suburban stands out as a widely recognized 2WD 3/4-ton SUV because of its advancing performance capabilities and practical features. In 1987 Chevrolet debuted the R2500 Suburban after discontinuing the C/K model names. The Chevrolet R2500 Suburban came with a 5.7L (350 CID) engine and an optional 7.4L (454 CID) V8 that boosted towing capacity alongside its robust durability. The R2500 model entered its new phase in 1987 when it transitioned from carburetors to electronic fuel injection which delivered improved engine performance and quick acceleration capabilities. The new 4L80-E 4-speed automatic transmission system that Chevrolet introduced during 1991 enhanced both the power delivery performance and driving dynamics by offering improved gear shifts and responsive power delivery. The R2500 Suburban featured automatic transmissions as its standard option while optional improvements brought available back support seats inside the cabin. The third-row door access became better thanks to Chevrolet replacing the traditional swing-out doors with tailgates or liftgates. Additional comfort features in the R2500 Suburban included HVAC vents installed specifically in the rear seat area for passengers. The standard tank of 25 gallons for the vehicle could be upgraded to 31 or 40 gallons to fulfill range requirements. Chevrolet ensures that R2500 Suburban's genuine parts provide durable performance through extensive quality testing before market release.
