suzuki SPOA?
g,day guys, before i do any mods to my suzuki i wanna know what i'm gettin myself into. the one thing i cannot get my head around is how does a spring under axle lift actually lift the vehicle enabling bigger tyres, such as 33's even 35's!
I have read a number of threads on this site and others and have seen how it is done, and understand that you use the standard leaf springs, but is there something i'm missing? I dont see how it actually lifts the vehicle  and what size lifts are we talking?

first of all what is your question?...
a spring over axel(spoa) conversion will take the leaf springs from underneath your diff and will put them on top i think it gives you around 4inchs of lift with standard springs. as far as i know its no the easiest thing to do as you will need to weld new spring pads on top of the diff and get your castor angles and pinion angles correct. if you are looking at doing this you will need to talk to an engineer because they are not legal with out a lane chnage test and need to be engineered. a leaf sprung car wether it be spring over or spring under gets its lift by using a spring pack with a bigger arch, but (just to confuse you) by doing this and fitting bigger tyres the tires may rub on the gaurds because although the spring is lifted it still has the oppertunity to go to full compression which will cause the tires to rub. to stop this longer bump stops are recomended but not necesserely needed. i hope this helps somewhat but if it has confused you then im sorry. 1 more question, do you want to fit 33's or 35's to your sierra? if so why?

aww ok i see where i'm gettin mislead. the springs come standaard over the axle and the conversion (SPOA) is actually taking them and putting them above the axle and thats where the lift comes from! man that was pretty stupid of me
 ...sorry bout that!

the gears and lift required to run 33"s with springs under axle will set you back about $4100-$4500 if you install all the gear yourself. And you will prob have to move your front diff forward 30-35mm. add another couple of grand if you are paying a workshop to do it all. Then all your axles will break and you will want to upgrade everything else

2 inch bodylift = $259 http://www.locktup4x4.com.au/catalog...1edb7d2a1.aspx 6.5 gears = $899 http://www.locktup4x4.com.au/catalog...1edb7d2a1.aspx Driveline spacers = $100 http://www.locktup4x4.com.au/catalog...1edb7d2a1.aspx Bushes = $65 http://www.suzistore.com.au/shopdisp...RRA+SJ70-W%2FT U-bolts = $88 http://www.suzistore.com.au/shopdisp...RRA+SJ70-W%2FT Fitting yourself parts will cost you just under $2400. Move diff forward by redrilling spring perch, you may need to lower your bumpstops which is easy enough with steel square tube, and if you manage to get the flex out of the springs then add extended brakelines for around $150. You shouldn't start breaking too much until you lock the front end or upgrade the motor and have a heavy right boot. Liam as Simon said to you in the other thread work out what type of 4wding you want to do before you start worrying about what mods you will need to fit what tyres.

yeah i want to do more mundaring style driving, through quite rough terrain, some rock climbing, mud, etc. not so much beach driving. I just thought that SPOA might be they way to go, judging what other people have posted on other threads in regards to it being cheaper to do if i wanted to run the larger tyres. I will be getting transfer gears and eventually a rear locker. i also understand that it does require it too be done correctly to be effective and i'm not too worried bout the legal side of things as i have another car for a daily driver and this will basically be a weekend warrior, maybe the odd run to the shops, but thats it.
sorry bout all the questions, i'm totally new to the game.
