Accessories and Other Modifications
~Factory fitted hardwood floor steel tray back
~ECB Aluminium Bullbar
~Lightforce 240 Blitz Spotlights
~Uniden 80ch UHF radio
~2.5" exhaust system
~Custom divorced 2.5"/1.875" into 3" turbo dump pipe


In Progress Modifications
~Rebuilding and installing a set of 4.1:1 HJ60 land cruiser full float axles front and rear
~Fitting 15x10 Steel rims with 35x12.50r15LT Maxxis Creepy Crawlers
~Custom rear leaf spring setup consisting of converting to 70mm(2.75") wide 1415mm long leaf springs from a VW Amarok.
These will be spring under with an upside down shackle to keep the ride height low with lots of down travel.
They also have a huge diameter (60mm) front bush which will help with NVH, supension dynamics and the all important flex!
I plan to run a 13.5" stroke ironman foam cell pro rear shock. I will be making custom out boarded leaf spring hangers and shackle hangers to suit the wider leaf spring mounting position of the land cruiser axles(1030mm/40.55") as opposed to the factory width(965mm/38")

~Custom Front leaf spring pack made up of a rear main leaf and military wrap secondary from a ln106 hilux (50mm longer length) and a mix of shorter front leaves from the rocky factory spring pack. I will also be running the same shocks from the rear to keep parts interchangeable as much as possible.

~Fabricating a very tight steel cradle to set my Warn 8274 into the aluminium bullbar
~Fabricating a rear winch mount for an eBay 11000lbs low mount winch

Future Modifications:
~Radius arm/Coil conversion in the front
~Wheelbase Extension +1 in the front and +2 in the rear
~37x12.5r17 s on Trailgear beadlock 17x9 Alloys
