20-40ft Extendable Container Chassis for Sale
One flexible chassis that hauls 20, 40, and 45-foot containers.
An extendable container chassis telescopes to carry 20, 40, and often 45-foot containers on a single unit. For fleets that see a mix of box sizes, this flexibility replaces two or three dedicated chassis and keeps utilization high.
American Chassis Depot supplies new and inspected used 20-40ft extendable chassis from Houston, Texas, with nationwide delivery, leasing, and lease-to-own financing.

The flexibility advantage
With multi-position twist locks and a telescoping frame, one extendable chassis adapts to whatever container comes off the ship or rail. That means fewer assets sitting idle, simpler yard management, and the ability to accept mixed freight without turning work away.
Cost, weight, and financing
Extendable chassis cost more up front and weigh more than a fixed unit, so they make the most sense when your freight mix truly varies. New units carry a warranty; used units are DOT-inspected. Purchase, leasing, and lease-to-own are available with fleet pricing on volume orders.
Frequently Asked Questions
What container sizes does an extendable chassis carry?
Most 20-40 extendable chassis handle 20, 40, and 45-foot containers using multi-position twist locks and a telescoping frame.
How much does an extendable chassis cost?
Extendable chassis cost more than fixed units because of the telescoping frame; final pricing depends on condition, suspension, and quantity. Contact us for a current quote.
Is an extendable chassis worth it vs. a fixed one?
If your freight mix varies across box sizes, yes — one extendable unit replaces multiple dedicated chassis. For single-size operations, a fixed chassis is lighter and cheaper.
Do extendable chassis weigh more?
Yes, the telescoping frame adds tare weight (typically 10,500–12,000 lb), which slightly reduces max payload compared with a fixed chassis.
Is leasing available?
Yes — purchase, leasing, and lease-to-own are all available, with fleet discounts on 10+ units.
