Watch A 4x4 is Born Season 1 Episode 5 Online

It's Mark's favourite part of the project - rebuilding and upgrading the monster V8! Cleaned, stripped of its ancillaries and decapitated, Mark assesses its condition. Mark visits a gearbox specialist to rebuild an R380 gearbox and transfer box from scratch for his project vehicle. Meanwhile, the completed, blasted chassis is galvanised by the hot-dip process. It's a very dangerous procedure but the finished chassis looks magnificent.
