Chevrolet R20 Suburban Parts & Accessories

The Chevrolet R20 Suburban is the three-quarter-ton two-wheel-drive variant of the full-size classic Suburban, designed to handle heavier passenger and cargo loads than the half-ton models. These full-size SUVs are popular platform vehicles for camper conversions and heavy family haulers.

Popular Upgrades

Exhaust systems and headers designed for the 350 or 454 V8 engines are the most common power upgrades. Suspension leaf spring upgrades with higher load ratings improve ride quality under payload. Intake and carburetor upgrades help the large displacement engines breathe better and deliver improved throttle response for towing applications.

What makes the R20 Suburban different from the R10 Suburban?

The R20 Suburban uses a heavier-rated rear axle, higher capacity leaf spring pack, and heavier-duty brake components compared to the R10. This allows it to carry more passengers and cargo safely while maintaining the same classic Suburban body style.

What suspension upgrades are popular on the R20 Suburban?

Heavy-duty leaf spring replacements and upgraded shock absorbers are the most common first suspension upgrades on R20 Suburbans. For builders looking for more lift, a 2-inch to 4-inch lift kit using new blocks and U-bolts on the rear is a popular approach.
