Aussiemj Posted December 11, 2020 Share Posted December 11, 2020 Hi guys My Mj I belive has a 6 inch lift which is totally illegal in Australia. I would survive about 10 minutes before police took me of the road . Can anyone tell from the photos is rear spring standard or modify. The shackles are 6.5 inch hole centres. thanks cont Link to comment Share on other sites More sharing options...
Tex06 Posted December 11, 2020 Share Posted December 11, 2020 Well it's definitely a Spring Over Axle (SOA) which is modified in how it attaches to the axle (stock comanches have the axle sitting on the spring or SUA, Spring Under Axle). Shackle looks modified going from memory, hopefully someone else can chime in on that. Springs look to be standard spring packs with 2 helpers added, not sure if that's a stock metric ton spring or not. Link to comment Share on other sites More sharing options...
Jesse J Posted December 11, 2020 Share Posted December 11, 2020 the plate looks modified to me the shock on mine attaches to the plate and that one doesnt. its possible since mines an 87 and yours is a 90 it might be different. If I where you I would either a. keep the helpers and go SUA or b. get rid of the helpers and keep the SOA Link to comment Share on other sites More sharing options...
JMO413 Posted December 11, 2020 Share Posted December 11, 2020 That is definitely SOA which gives 5ish inch's of lift and a longer shackle. The springs definitely look to have an add a leaf also. Link to comment Share on other sites More sharing options...

Jesse J Posted December 12, 2020 Share Posted December 12, 2020 8 minutes ago, Pete M said: what is the maximum that is legal? 150 mm which is just under six inches. a least according to the top google answer SOA with 2 inch shackles seems like a 6" lift but it seems a little taller Link to comment Share on other sites More sharing options...

I’m using a set of XJ Cherokee leaf springs and replacing all but the main leaf on my Comanche with them. The Cherokee springs have less arch and will bring you down a bit but likely not enough to be legal. You can switch back to spring under axle and you’ll have some more options for 4” or under Link to comment Share on other sites More sharing options...
Jesse J Posted December 12, 2020 Share Posted December 12, 2020 I would keep the shackles and go back to SUA. you'd probably have to go down a tire size as well Link to comment Share on other sites More sharing options...

Jesse J Posted December 12, 2020 Share Posted December 12, 2020 you probably need new shocks but thats all I can think of Link to comment Share on other sites More sharing options...
Dzimm Posted December 12, 2020 Share Posted December 12, 2020 It looks like the under axle spring pads are still on the axle. Can you confirm this? If so it would be as simple as swapping the packs back under the axle and flipping your u-bolts/plate. Link to comment Share on other sites More sharing options...
Pete M Posted December 12, 2020 Share Posted December 12, 2020 if he used the stock driveshaft, than that part will be ok. but if you got a new one made to match the lift, it might be too long for a lesser amount. flipping the springs back under the axle will bring it down to almost stock height. if you want a 4" lift again, you'll need to buy 4" lift springs.
