I have what I assume is a 2 inch lift right now and I was thinking about getting the 5 inch shackles from man a free, the only thing that I am concerned about is the towing and snapping a spring. my 62 is my dd and my playtoy. So what do you great people of mud think?
I' don't understand how the shackle length would cause a spring to snap while towing. Your rear shackle , stock, is about 1" longer in the rear than front. If you sit level now be aware of that. A 5" shackle in the rear would match a 4" in the front
I think there's a lot of Aussie posts here. The Americans here aren't aware of how restrictive your rules for modification are. I had Rod from Kamar
here for a week while he developed his FJ Cruiser rear "bar" and we got into long discussions of laws over there. As I understand a manufacturer can't build a component that requires drilling new holes in the frame or welding to the frame to mount the products. Lift laws are also quite restrictive.
I think Americans push the limits a little farther because we can without the government stepping in. Since 1978 my daily driver has been a Land Cruiser of some kind. It's always been a leaf sprung, live axle version and I've always had at least 4" lift that incorporated a longer shackle than stock, generally
about 2" over. I would venture to say I have well over 500,000 miles on Land Cruisers with that type of suspension. I've only had failures on one shackle. It was a stock FJ60 front shackle that I broke on a rock while crawling over a large boulder on the Holy Cross trail in Colorado. Now it has a shackle reversal so it doesn't drag anymore
