Defender (2007-2016, Puma) Chassis

The Defender uses a separate box-section steel ladder chassis rather than a monocoque body, which is typical of proper off-road 4x4s. On Puma-era models (2007 to 2016), the chassis carries the engine, running gear and body separately, so the bodywork can be removed for a full rebuild. Many replacement chassis are supplied galvanised for better corrosion resistance than the original painted steel.

The cost varies considerably depending on the specification of the replacement chassis, whether it is galvanised, and how much labour is needed to strip and rebuild the vehicle onto it. A full chassis swap is a major job, so labour time usually costs more than the chassis itself. Getting a quote from a specialist who knows the model year is the best way to get an accurate figure.

Several specialist manufacturers produce replacement Defender chassis to original specification or with galvanised finishes for extra durability. The best choice usually comes down to whether the chassis matches the exact model year and fitment of the vehicle, since Defender chassis design changed across the Puma and earlier generations. Buying from a supplier with clear fitment information reduces the risk of ordering the wrong version.

Replacement chassis and chassis sections are available from Land Rover parts specialists, including Moss Rimmer, who stock components for the Puma-era Defender. It helps to have the vehicle's chassis number and build year to hand so the correct fitment can be confirmed before ordering.

A full chassis change is a substantial job that typically takes several days to over a week for an experienced garage, depending on the condition of the vehicle and how much has to be transferred across. Rust, seized fasteners and the need to strip the body, running gear and interior all add to the time required. A specialist Land Rover garage will usually give a more accurate estimate once they have inspected the vehicle.
