The CRDSTU KJ 2.5” system is our benchmark kit that started Murchison Products way back in 2006! We were filling the void the other manufacturers left thus creating a true load bearing 2.5” Kit that doesn’t sag. This kit carries the weight of both Petrol and CRD KJ’s with and without a front bar and / or winch. Ride quality was dialed in right from the word go and this kit was tweaked over a 12 month period to ensure perfection. Our kit offers the most flex out of any KJ kit currently on the market and is all Australian Made.

This kit contains:
• Front & Rear Long Travel Struts and Shocks
• Front Strut Top plates (sold as pair only) KJSP01
• Front Coil CRDSTU 01
• Rear Coil CRDSTU 03
• JBA Upper Control Arms
• New Crown HD Lower Ball Joints

About JBA Upper Arms: 
If your KJ is above 80 – 90,000 KM, it would be advisable to install some JBA Upper A-Arms with this lift. They are complete new HD upper control arms that are designed to cope with lift and run a much heavier ball joint. The factory arms lack coil clearance when lifted springs are installed and can come into contact with the upper ball joint boot. The Upper stock ball joint is also only just capable of running a lift so these new Upper A Arms correct the ball joint geometry and sit the ball joint more square at normal ride height thus achieving a better resting angle. Less angle means less stress on the ball joints. This ball joint is also greaseable and replaceable unlike the factory item – they can be found here

Please Note:
• Front Strut Top plates come standard in all of our kits, however these are not needed on a Petrol vehicle without bullbar.
• We also sell the Strut Top Plates separately, these can be found here

Recommended Upgrades

Crown Front & Rear Bump Stops Replace those old soft rubber or foam factory bump stops with these high quality polyurethane bump stops. Worn front bump stops or no bump stops at all are the biggest cause of shock failure due to bottoming out, so when you’re upgrading the suspension it’s always a good idea to have a set of these ready to install.
