The Chevrolet G20 was a full-sized van produced by General Motors and for a while became the staple of the North American van fleet.

The G20 and it counterparts replaced the original Chevrolet Corvair Greenbrier Van in the late 60’s the model line evolved until it was replaced in 1996 by the Chevrolet Express. 1964-70 G20s came with six-lug rims (6 lugs – 5.5″ (139.6 mm) bolt circle), while the 1971-96 generation came with the 5 lug – 5″ (127mm) bolt circle.

G20s were fitted with the ball joints from the Chevrolet/GMC 3/4 and 1 ton pickups although using the 1/2 ton pickup’s brake rotors.

A light duty version, the G10, was produced alongside the G20 – the early versions used the Chevrolet passenger car rims (5 lugs – 4.75″ (120.7 mm) bolt circle) until 1975 (G10s manufactured prior to the 1976 model year had the smaller bolt pattern, common with the short wheelbase vans). But can still handle LT tire sizes for better handling and stability. the G20 series sported an SB 262 4.3L engine, not much was changed mechanically in the vehicles since their release. Other than carberator to a throttle body. And less use of a vacuum system. Currently there are more after market part options available for its V8 counterparts. Not much has been done in the lines of performance options for the small V6 G20 models. But the reliability remains the same throughout all the G-series models.

The G20’s low cost of upkeep size and options, have made this van popular with all different kinds of trades, from plumbers to caterers.
