2 mm (14swg) steel and treated with zinc phosphate,
cathodic electro coated, followed by waxing in the rear
crossmember.
Outriggers and angled brackets welded to the chassis
support suspension and axle components and are
also used as body mounting points. A detachable box
section crossmember, located between the two
chassis longitudinals is fitted to facilitate main gearbox
and tranfer box assembly removal.Should chassis damage occur, a comprehensive
range of components are available, including body
support outriggers, cross members and radius arm
mounting brackets. ALWAYS fit genuine parts that are
fully guaranteed and to original equipment
specification, fitted with Land Rover’s BS 5135
welding standard.
Body
All body panels, with the exception of the fascia
bulkhead, are manufactured from aluminium alloy.
Galvanized steel is used for the front wheel arches to
give optimum protection. Most panels are also treated
with zinc phosphate and cathodic electro coated with
polyester surfacer, and are bolted to the welded
chassis.
