Rear sag - best cure?

I went to the water. He suggested that I look into new springs first.

Definetly need new springs, those are beat.

With 2" perches I wouldnt run a zero rate for fear of wrap.

A set of 2" lift springs would level that baby out nicely.

Btw, shackles arent the best way to raise a vehicle.

When you get into suspension theory, shackle angle, shackle length, spinr length etc all play important roles.

DONT just throw longer shackles on. It may get you up but it wont perform like it used too

I was given a good rule of thumb that shackle length should be 10% of spring length. So I figure 6" shackles on 56" springs is a good number.

I'm sure that I will end up with a set of shackles too.

Looks to me like re-arched or new springs are in order.

stop screwing around and get yourself some all new springs.

The only rule of thumb is, there is no rule no thumb. Shackle angle, spring arch, amount of travel required (up and down) are all essential to "getting it right"
