Chevrolet Express 3500 LS, LT, Diesel & More

Last updated August 4, 2026

Chevrolet Express 3500

The Chevrolet Express 3500 lineup splits into passenger, cargo, and diesel branches. Base Model covers the straightforward LS passenger vans, while Work Truck is the durable cargo-hauling branch. Comfort Upgrade covers the LT passenger vans, which have a more finished cabin but can be quite close to LS depending on year. The older diesel branch follows the same basic pattern: Diesel is the cargo van, Diesel Base combines LS-style passenger duty with diesel pulling power, and Diesel Premium pairs the LT-style passenger cabin with the diesel engine.

Frequently asked questions

What is the difference between Regular and Extended Express 3500 cargo vans?

Length and enclosed space are the main differences. On newer cargo vans, Regular uses a 135-inch wheelbase and has about 239 cubic feet of cargo room. Extended uses a 155-inch wheelbase and has 283.6 cubic feet, but its longer body needs more room to maneuver.

What does the LT add over the LS on an Express 3500 passenger van?

The LT is the more finished passenger trim. On many older vans, it adds cloth seating, carpeting, rear climate support, cruise control, and convenience features over the simpler LS. Recent LS and LT equipment overlaps more, so check the exact van.

Are Regular and Extended comfort trims on the Express 3500?

No. Those names mainly describe body length. Cargo vans are commonly labeled Regular or Extended, while passenger vans combine an LS or LT equipment level with a Regular or Extended body.

What is the difference between a Work Truck and an LS Express 3500?

They serve different jobs. The Work Truck is a cargo van with a durable floor and open load area for tools or upfits. The LS is a passenger van with seating and rear climate equipment for moving groups.

What is the difference between LS Regular and LS Extended?

On newer passenger vans, LS Regular has a 135-inch wheelbase and seats 12. LS Extended stretches to 155 inches and seats 15, giving a shuttle or group more passenger and luggage room at the expense of easier maneuvering.

What is the difference between LT Regular and LT Extended?

Body length and capacity are the key differences. On newer vans, LT Regular uses the shorter 135-inch body with 12 seats. LT Extended uses the 155-inch body with 15 seats while keeping the LT’s more finished passenger-van identity.

Which Express 3500 cargo version makes sense for a contractor?

Regular suits contractors who work in tighter streets or parking areas and do not need maximum enclosed room. Extended is better when bulky tools, shelving, or supplies make cargo space the priority.

Should I pick an LS or LT Express 3500 for shuttle use?

Pick the LS for straightforward, durable group transport. Pick the LT when a more finished cabin and added passenger conveniences matter for hotel, airport, church, or longer-distance shuttle work. Equipment varies by era, so inspect the individual van.

Which Express 3500 trims seat 15 people?

In recent years, the 15-passenger versions are LS Extended and LT Extended. Regular-body passenger vans seat 12. Some older diesel extended versions used different seating layouts, so confirm the installed seats and belts on the individual van.

How is an older Diesel cargo trim different from the gas Work Truck?

The older Diesel trim uses a 6.6-liter Duramax V8 for stronger low-speed pulling under heavy loads or while towing. It keeps the same basic rear-wheel-drive cargo-van layout. These diesel cargo versions belong to the 2010–2016 era.

What is the difference between LS Diesel and LT Diesel passenger vans?

For 2011–2016 vans, LS Diesel is the simpler setup with vinyl seating, a rubber floor, and front air conditioning. LT Diesel adds cloth upholstery, full carpeting, rear air conditioning, a rear heater, cruise control, and a tilt steering wheel.

What is the difference between Diesel and Diesel Extended cargo vans?

For 2010–2016 cargo vans, both use the 6.6-liter Duramax diesel V8. Diesel has the 135-inch regular body and about 240 cubic feet of room. Diesel Extended uses the 155-inch body and about 284 cubic feet.

What equipment comes in a newer Express 3500 cargo van?

Newer Regular and Extended cargo vans include a rear camera, heated power-adjustable mirrors, manual air conditioning, a durable rubberized-vinyl floor, and rear swing-out cargo doors. Exact equipment still varies by model year and upfit.

Does the D in LS D or LT D mean diesel?

No. In the older trim labels covered here, LS D and LT D use a 6.0-liter gas V8 with a four-speed automatic. The actual diesel passenger variants are identified as LS Diesel or LT Diesel.
