Installation Steps

1

Lift and support vehicle as recommended by Mercedes and remove rear wheels.

2

Use a 21mm socket to remove the upper shock bolt. Then use a 18mm socket and wrench to remove the lower shock bolt. Completely remove shock and set aside.

3

Clean the frame surface as necessary. The 2019+ Sprinter frame comes with two existing holes. The front hole is 7/8” and the rear hole is 3/4”.

4

Install the supplied 14mm x 100mm shock bolt to hold the AO Double Shear bracket against frame. Install the 7/8” frame/bolt sleeve through the front hole of the bracket and frame and the 3/4” frame/bolt sleeve through the rear hole of the bracket and frame. Install the supplied 1/2” x 4.5” bolts with washers.

5

Install the supplied 1/2” large diameter washers, 1/2” small diameter washers, and 1/2” nyloc nuts to the inside of frame. At this time do not fully tighten.

6

Install rear shocks using the supplied 14mm x 100mm upper bolts. Factory and Fox 2.0 shocks will require the use of the supplied 6mm thick washer. No spacer is required when using Fox 2.5 shocks. Re-use factory lower mounting hardware. Use red Loctite on bolts.

7

Torque the upper shock bolt to 105 ft lbs then install the bolt locking tab using the supplied 1/4” bolt, washer and nyloc nut. Torque the lower shock bolt to 75 ft lbs. Fully tighten the front and rear AO Shock Mount bolts and torque to 90-100 ft lbs. Repeat same process on the passenger side. Re-install wheels and torque lug nuts/bolts to the recommended wheel torque specs.
