Chevrolet R20 Parts & Accessories

The Chevrolet R20 is the three-quarter-ton two-wheel-drive truck in the classic square-body C/K family, built for heavier towing and payload duties than the half-ton R10. Restorers and daily drivers alike appreciate its rugged mechanicals and straightforward maintenance.

Popular Upgrades

Exhaust headers and performance cat-back systems designed for the big-block or small-block V8 are the top power upgrade for R20 owners. Heavy-duty suspension components including leaf spring upgrades and shock replacements improve load handling and ride quality. Intake systems and carburetor upgrades provide additional power for trucks regularly towing trailers or hauling payloads.

What exhaust options fit the R20?

Both small-block (305, 350) and big-block (454) exhaust manifolds and headers are available for the R20, depending on which engine your truck carries. Long-tube headers paired with a 3-inch cat-back system deliver the best power gains on the larger displacement engines.

How do I improve the towing capability of my R20?

Upgrading to heavy-duty rear leaf springs with a higher load rating is the primary suspension improvement for towing applications. Adding a transmission cooler and upgraded rear shocks completes a towing upgrade package that keeps the R20 stable under heavy loads.
