How to Install Max Trac 2 in. Rear Lowering Hangers on your F-150

NOTE: MAXTRAC HANGER REPLACES THE FACTORY HANGER AT THE FRONT OF THE LEAF SPRING, NOT ALL TRUCKS ARE THE EXACT SAME, THESE INSTRUCTIONS ARE FOR THE GENERAL INSTALLATION OF LOWERING HANGERS.

*THE 420520 HANGER WILL REQUIRE THE BED MOUNT TO BE TRIMMED DOWN

*THE 420920 HANGER WILL LINE UP WITH 3 HOLES ON THE FRAME AND 1 HOLE BELOW

1) JACK UP REAR AXLE AND SUPPORT TRUCK UNDER FRAME WITH JACK STANDS.

2) LOOSEN, BUT DO NOT REMOVE BOTH BOLTS AT THE SHACKLE

3) LOOSEN, BUT DO NOT REMOVE THE SPRING BOLT AT THE FRONT OF THE LEAF SPRING

4) LOWER THE REAR AXLE ENOUGH SO THAT TENSION IS TAKEN OFF OF THE FRONT SPRING BOLT AND REMOVE BOLT

5) USING A DIE GRINDER OR ANGLE GRINDER WITH A CUTTING WHEEL, MAKE ONE CUT DOWN THE MIDDLE OF EACH RIVOT HOLDING ON THE FACTORY HANGER, ALL THE WAY THROUGH THE HEAD, BUT NOT INTO THE SURFACE OF THE HANGER

6) USE A NEUMATIC HAMMER WITH A CHISSEL ATTACHMENT TO REMOVE THE HEAD OF THE RIVOTS. (RIVOT HEADS SHOULD COME OFF RELATIVELY EASY, IF NOT, MORE CUTS MAY BE NECESSARY)

7) USING A NEUMATIC HAMMER WITH A PUNCH ATTATCHMENT, PUNCH ALL RIVOTS THROUGH THE HANGER AND REMOVE THE HANGER

8) INSTALL THE MAXTRAC HANGER USING PROVIDED HARDWARE AND TIGHTEN (FOR THE 420920 HANGER, 3 BOLTS LINE UP ON THE FRAME AND 1 BELOW)

9) RE-INSTALL THE LEAF SPRING INTO THE HANGER USING THE FACTORY BOLT, BUT DO NOT TIGHTEN.

10) ONCE THE TRUCK IS OFF THE JACK STANDS AND COMPLETELY ON THE GROUND, JUMP ON THE REAR BUMPER A FEW TIMES TO ENSURE THE SUSPENSION IS COMPLETELY SETTLED, THEN TIGHTEN ALL 3 LEAF SPRING BOLTS
