lifting the courier

My mate wound his up on the front and put raising blocks in the rear and gained 50mm easily but made for a very rough ride......(Mazda Bravo) 1996....But he is fine with that....

you can screw the adjuster up but, if it effectively winding the tension up on the rod, it is the same as heating a coil spring up so that it sags ie. lowers, but has no travel as the gap between the coils closes up. you can do it but the ride quality will be as if it is on the bump stops, ie no travel. this make sense mate? you can get the torsion bars reset aswell but at a cost of course.

Course you can do it and Im sure you will be very pleased with the results.

Just dont go too far!!
If you wind them up too much you eliminate the 'droop' of your front suspension and this creates a terrible ride and poor articulation.
Idealy in the middle of bump and droop is best, but I prefer a tad higher than middle. Gives slighlty better clearance and still good artiiculation.
If you want an easy rear lift to compliment your front (we are only talking small lift) try a set of air shocks or extended shackles.

I did this on my Mu (rodeo suspension) about 5 years ago and it worked a treat. The truck was bottoming out on the bumpstops all the time( couldnt afford new torsion bars and springs) , wound up the front and threw the air shocks on the rear. The shocks dont exactly 'lift' the rear, but by taking an amount of load of the springs, the rear does then ride slightly higher (level with front).
You then have the added bonus of load leveling with the air and the forced articulation that linked air shocked give you when off road.

Goodluck with it.
Matt.
