any one know what this is i read it some where and don't know what is is reffering to any ideas? thanks

 

u asking about shackle reversal on front or rear? on front it moves the shackle to the back of the srping. on the rear you flip the mount and have shackle hang down instead of up, normally called a shackle flip.

on ttb front ends it would be hard to do reversal and keep the front end correct.

 

there any benifits to doin a shackle flip on the rear

 

will give about 3-4 inches of lift.

 

my axel on the rear is under the springs is this alerady fliped?

 

well what ur thinking then is sring over axle vs spring under alxe. ur springsc came stock on the top. what i mean is the shackle in the rear of the spring. u sill see that it it going up to the srping. well u cut off the riviots and make a new hanger to make the shackle go down to srping.
