Series Land Rover Chassis

The pre-production Series 1 Land Rovers had a galvanised chassis and the front bumper was integral with it. Production models dropped the idea of a galvanised chassis and had a steel chassis and separate bumper. The first Series I's had their chassis painted silver but for later models it was changed to green. In 1951 the chassis was strengthened with transverse bracings and outrigger supports. The Series I Land Rover chassis changed several times during the Series I production.

The basic design of the chassis for 88in and 109in Series Land Rovers is similar in that they are constructed of box girder cross sections in a ladder style arrangement. The overall length of an 88in chassis for a Series Land Rover is 342cm (excluding bumper) and for the 109in it is 424cm (also excluding bumper). The width ot the rear chassis cross member is the same for the 88in and 109in and they are also interchangeable. Some of the outriggers, especially towards the rear of the chassis are interchangeable. The outriggers nearer the front of the chassis can vary slightly in design and also in location, due to the different body styles available for a Series Land Rover and the specific support which those different body styles require.
The 2.6litre and 2.25 litre LWB chassis have the front cross member in the same position but the engine and gearbox cross members are further back to allow for the longer Land Rover 2.6 engine; the crossmember behind the gearbox is also further back.

The Stage One V8 109 Land Rover chassis has the front cross member further forward and supports the radiator. There is no crossmember beneath the engine and so a bolt on crossmember is added between the two bulkhead outriggers to return strength and rigidity to the chassis. It should be noted that the Stage 1 V8 gearbox is fixed by bolting it through the chassis, so if a different chassis is used for a V8 gearbox set, then ferrules (thin strengthening tubes) should be fitted inside the chassis to prevent the chassis being crushed on tightening the gearbox mounting bolts .

It is still possible to obtain replacement outriggers if corrosion dictates that a new one is required. They are all quite basic in construction though and can be fairly easily fabricated given some suitable gauge metal. If the vehicle is to be used offroad, then full strength is required from the chassis and a full replacement is recommended. The cost of a galvanised chassis for a Series 1,2 or 3 Land Rover has hardly changed in the last 15 years.
