Kojack 150 mm Extension Piece – Boost Your Jack’s Reach with Confidence
The Kojack 150 mm Extension Piece is an essential accessory for your Kojack hydraulic RV jack kit, designed to give you extra height and flexibility when lifting. Whether you’re dealing with a high-clearance caravan, uneven terrain, or just want that extra lift, this extension helps you get the job done safely and effectively.
Lift Higher — Reach Further
By adding this 150 mm extension to your Kojack kit, you increase your lift height significantly. It boosts the maximum jack height from around 600 mm up to roughly 750 mm, giving you the extra reach you need when working on lifted rigs or tackling difficult terrain.
Tough, Reliable Construction
Built by Purpleline with durability in mind, this extension piece features rugged, high-quality materials that withstand regular use. It works seamlessly with Kojack’s existing collar and head adapters, maintaining the structural integrity of your jacking setup.
Simple to Fit
Installation is straightforward. You remove the existing collar, insert the 150 mm extension, and then re-fit your head adapter (round or square) using the grub screws — just like the standard setup. Once in place, you’ll notice the added height immediately.
Designed for Versatility
This extension works with the Kojack Hydraulic High‑Lift Jack (for example, the Kojack 4T models) and is compatible with both round and square jack heads. That flexibility makes it perfect for a broad range of caravans, trailers, and RV setups.
Built for Real-World Aussie Conditions
Kojack gear is built to handle tough environments. With this extension, your jack remains up to the task, even when you’re parked on soft ground or rough off-road terrain. Thanks to its robust design, it won’t compromise the safety or function of your jack system.
