Lincoln K Series: 1931–1940 Luxury Classics and What to Know Before Buying
Lincoln K Series (Model K) — 1931–1940 American luxury cars with V8 and later V12 engines. We look at what makes them special, which versions were offered, and what you need to know if you're considering such a classic car.
K Series in brief
The Lincoln K Series replaced the earlier L Series and was the luxury flagship in the US market. It competed with the Cadillac V12 and V16, Packard, Chrysler Imperial, Pierce-Arrow, and Duesenberg Model J, as well as European luxury marques.
Besides factory bodies, Lincoln also sold bare chassis to coachbuilders. Production ended after the 1939 model year, with remaining cars sold as 1940 models.
Versions — What's the Difference
The first Model K appeared in 1931 with a 3,683 mm wheelbase and a 6.3-litre V8 engine producing around 120 hp. In 1932, the series split into two lines: the V8 Model KA and the new V12 Model KB.
Later, the V12 line became the mainstay, with bodies built both in-house and by external ateliers. There were many body styles: from two and four-door phaetons to cabriolets, sedans, and limousines.
Engines and Transmission
The first Model K engine was a 6.3-litre (384.8 cubic inches) V8, developed from the L Series 60-degree V8. It was improved with a dual-chamber Stromberg carburettor, higher compression, and revised camshaft timing.
The V12 engine introduced in 1932 became a hallmark of Lincoln for nearly two decades. It was the prestige option in the luxury class of that era.
The condition of a classic car depends on the quality of its restoration. Parts often need to be sourced through clubs and specialist suppliers.
What to check when buying a Lincoln K
A classic luxury car requires a thorough inspection: chassis and engine numbers, body originality, body shop markings, and restoration history.
Inspect the frame, body construction (some of these vintage bodies used wooden frames) and interior for rust or rot. Check the engine oil pressure, cooling system, brakes, and electrical system.
Due to its large size and expensive parts, restoration can be costly. Before buying, ensure the seller has a complete documentation history.
