You will have about 31.5 gallon tank when done. You may consider changing the gear ratio depending on the size of tire you are going to run."
I had my Advanced 4WD Systems, Conversion, done in mid 2015.
I am not unhappy with the job they have done. The welds
are good, I have genuine Dana 60 Diffs front & rear with Warn Locking Hubs, Rancho 9000 adjustable shocks with Leaf Springs.
I have since revisited the shop & sent 4 emails asking for exact build components, but have had no response. I am in Australia.
I have since upgraded front Rotors to Slotted & Grooved Discs and matching Ceramic brake pads on the front axel.
Drove around the US for six weeks, 13 States & 11,000 miles and SMB performed perfectly, even in Arizona/Sth California with temperatures of 105-118f in late July 2015 and diesel engine had 256,000 miles on Odometer.
I spoke with a well known Spring Maker in CA, earlier this week, I described the suspension build by Advanced 4WD
and he said the two flat leaves on the front suspension were probably from an F250/350. They perform well, sit level, look very solid.
But the problem with Advanced 4WD System, is that you do not know what you have got. The workmabship is good. Conversion to 4WD cost $11,000.
Sportsmobile West system is a much beefier spring pack front & rear by Deaver or similar, custom made, new Dynatrack Axels & Locking Hubs. And the Atlas 2 Transfer system. All new, probably $8-10k more, but you get what you pay for.
Randy has done a lot of 4WD conversions, probably thousands and a few complaints. He could help himself and give you a detailed report on what has been installed.
I'm not unhappy, just need to know!
I went with Advanced System becauae Sportsmobile West build time and wait time was so long.
Sportsmobile West service backup is the best and very helpful.
My biggest concern is the front Spring pack by Advanced, may not big enough. So, eventually, I will ship vehicle back to US and have Agile Offroad, Ujoint, Sportmobile West or Ramsey at MGMetalworks for upgraded Leaves & other parts.
Do the research, and then even more research. Find out before the job, whoever it is, what are the exact components being used, new or rebuilt! Look at other vehicles with similar works that you want, take pictures, go to a couple of Overland or NW Rally events, take photo's, talk to SMB owners & workshop owners. Take your time, this vehicle will cost YOU a lot of money and/or downtime if you get it wrong. Or a great safe time, when you get it right.
My build with Right Hand Drive conversion has taken 3 years from purchase of van on Ebay.
