ATTACHING THE LOWER BRACKET TO THE AXLE

1 .  Push the lower bracket up against the stock U-bolts so that the legs of the lower 

bracket are locked into position around the stock U-bolts (Fig . D .44) . It may be 
necessary to rotate the lower bracket on the jounce bumper strike plate in order to 
do this .

2 .  Make sure the cup on the bottom of the lower bracket is nested onto the jounce 

bumper strike plate and the flanges of the cup are touching the strike plate on both 
the front and back side (Fig . D .45) . If it does not sit on the jounce bumper strike plate 
correctly, the cup swivels on the main plate . Rotate or move the cup to obtain this 
condition . 

 

3 .  Position the U-bolt around the leaf spring assembly and insert in the hole closest to 

the leaf spring stack (Fig . D .46) . The lower bracket flanges must be locked on the 
front and rear of the stock U-bolts holding the leaf springs to the axle .

Use closest hole to 
the leaf spring .

Make sure the cup is 
seated onto the jounce 
bumper strike plate 
forward and behind the 
axle .

Rotate the lower 
bracket on the spring 
perch if necessary and 
push the bracket up 
against the U-bolts to 
put the lower bracket 
into position .
