NOTE: Cheap, foreign aftermarket springs are not recommended. We have had issues with the military wrap leaf being way too large and contacting the hanger. This is not an issue with quality USA-made springs.

We have had a few customers with worn out spring bushings and sliders have issues with clearing the shackles on the 2" FSR kits with the military wrap. You need quality to specification parts to make this work (if using used springs with this kit).
Instructions for Replacing Leaf Spring Bushings and Isolators
It is common for the front frame horns to spread due to age as the only thing holding the front of the frame together is the rivets at the engine cross member. You may need to pull the frame together to get the hanger on.
These trucks were not built to a high level of precision. Some of the rivet holes may need to be opened up with a die grinder as the holes may not line up perfectly.
When installing this kit with lift springs, the springs are often shorter than stock as they are re-arched stock springs to get more lift. We recommend drilling just one hole for the spring hanger and holding it in place with one bolt until you are able to set it down and check to see that the shackle angle is satisfactory. Then drill the remaining holes.
