Stupid question abou articulation

[Richie]

Whats the best way to see how much articulation and flex the springs have on my none running sj 410?

I need to decide if they are better then the ones on my other sj but i cant decide how to do it, i dont really want to swap them over and find they are no better.

Best methods welcome

i'd just put a jack under the shock mount and jack it up until a one of the other 3 wheel lifts. However shocks will come into play as well as springs.

That won't apply the full amount of leverage really. I use my engine hoist attached the a wheel but if you haven't got an engine hoist you really need to drive it up a ramp.

Is this the one with parabolics? If so I can almost certainly say the rascals and rears up front set up will give you more flex.

Both of the sj's are right next to my 2 poster, maybe i can use that somehow instead of a engine hoist?

The non running 1.6 has the parabolics on it, the 410 has standard springs on it and the suposably rascle ones lay on the workshop floor next to i think 6 other standard ones.

Are parabolics really not that good then? They look fairly cool, do u think parabolic or bedford springs would lift the truck more?

See if anyone can work this out, how much lift these springs are giving on truck 1?

Truck 1 (this is 1'' higher than truck 2)
3 inch body lift kit
27 inch tyres
Shackles front and rear bolt hole to bolt hole 7 1/4 inches
parabolics springs

Truck 2 (this is my road truck and is 1'' lower than truck 1) :(
2 inch body kit (home made)
31 inch tyres
Shackles front and rear bolt hole to bolt hole 5 3/4 inches
standard springs
