Outer Limits 4x4 Board

Just after peoples experiences with shackle reversals, 60,40etc
Wondering how it affected steering suspension etc..
Its a sprung under set up mine!
Thanks Denny

This is an age old debate with just as much for as against.

I have done a SR on my 75. Things i have found include;

For:
No shackle hanging down at the front to catch on anything on approach.
Diff moves back on compression allowing a more fluid movement over rocks and ruts.
Brings the diff forward as you 180deg the springs increasing approach angle.

Against:
Less room for steering box pitman arm
Without a dropped front hanger the springs are on a bit of an angle.
People are complaining about problems with steering and bumpsteer but im yet to see any of those.

Its really a personal choice, if your willing to suck it and see.

one of my mates just bought a bolt on kit from ryno tech at rainbow beach. Cost him about $700 and rob told us that it will get a 4" lift out of it. We haunt fitted it yet. What is bump steer?

self steering from road gradients or potholes/bumps

ok so dose the steering try to fight you

also don't forget wit SR the vehicle may have a tendancy to understeer a heap, will use lots more spline in the slip joint and when cycling will point the pinion away from the transfer leading to yokes binding.

I find it strange that in the US one of the reasons fro getting a SR is for lift. The reason they get the lift is that they use extended hangers for the fixed spring end. If you wanted to, you could just grind off your existing hangers and replace them with extended hangers. You won't get a spring reversal, but you will get a lift. I wouldn't recomend it, but it is essentially how the SR lift works.

Thanks to all who replied, not so much lift i want, just sick of smashing the shackles, just gotta get used to hitting obstacles with a slightly turned wheel........Happy with it otherwise, might leave it for a while, work on my rollcage next.

The reason for using the extended hangers is the negate the need to cut and turn or shim for correct caster. By using the rear fixed hanger at the front, this effectively raises the spring eye by the length of the shackle. By installing the shackle at the rear, below the frame, the shackle has lowered the rear end of the spring by the length of the shackle.. Therefore, the spring has been rotated around the axis of the axle, altering the caster..

Also, by design, the shackle eye of the spring is forward of the frame hanger eye by ~40mm?, so installing the original fixed rear hanger at the front moves the spring rear by the same amount.. The extended hangers they use in the US bring the new fixed point down and forward to where the shackle wouldve been originally, keeping the suspension geometry close to where it was..

I'd only ever consider doing SR with SOA, not SUA. Not worth the hassle otherwise..
