We've been a bit quiet on the socials for a while (too busy building cars and designing the Ranger Super Duty 6 Wheeler conversion) but here's a few recent builds.

Still doing plenty of Standard Duty Rangers and a couple of Amaroks, because the Super Duty's great but doesn't offer the weight distribution or tray length that our customers need.

Our 4.5t Ranger and Amarok conversions have around the same payload, GVM and GCM as the Super Duty, with 2.4-2.7m tray and much better weight distribution.

The Ranger Super Duty project is making some headway. All of the structural and suspension components are designed and ordered!

The guinea pig is ready and waiting.

Watch this space!

Here's some Super Duty Ranger design trivia, for those that are interested.
The Super Duty Ranger rear axle is 260mm wider than a track-corrected Landcruiser 70 series rear axle, which makes it ~360mm wider than a Standard Landcruiser 70 series rear axle!

Because the Super Duty runs 55mm positive offset rims, the track difference is 150-250mm, compared to a GXL and 190-290mm, compared to a Workmate.

The Super Duty is a pretty big rig!
