Installing the Expansion Tank Kit

The purpose of the expansion tank kit is to provide a smoother ride

by acting as an add-on volume for the air springs. When the air

spring system is faced with rough road conditions, pressure builds in

the air springs. Under these conditions, the expansion tank gives

the air in the air springs somewhere else to go and decreases the

pressure and the spring rate.

While adding the expansion tank kit will improve the ride of your

vehicle, it will not affect RoadTamer’s carrying capacity. Do not

exceed the GVWR rating for your vehicle.

Hardware List

IMPORTANT NOTE: Depending on the orienta-

tion of the tank once it is mounted, the fittings may

go into different ports on the tank. The drain valve

must always be put into the port facing downwards

(Figure 2).

IMPORTANT NOTE: Apply the provided thread

sealant to all of the air tank fittings that have not

been pre-coated with sealant.

1. Attach the two air fittings to the ports on either end

of the tank (Figure1).

2. Choose a mounting location for the accumulator

tank.

NOTE: Be sure that there is ample room for the

air lines and that they will be clear of any heat

sources.

3. Attach the swivel elbow fitting to the port on the

expansion tank that will be facing upwards once the

tank is mounted (Figure 1).

4. Attach the drain valve to the port on the expansion

tank that will be facing downwards once the tank is

mounted (Figures 1 and 2).

5. Attach the plugs to the two remaining ports on the

expansion tank (Figures 1 and 2).

6. Attach the tank to the chosen mounting location

using the provided bolts, flat washers, and nyloc

nuts (Figures 1 and 2).

Attaching the Air Lines

1. Deflate the rolling lobe air sleeves and disconnect

the air fittings from the sleeves. Remove the

existing air fittings from the air sleeves.

2. Attach the supplied 90° 1/4” x 1/2” air fittings into

the air ports at the top of the sleeves (Figure 1).

3. Connect a length of air line from one 1/2” air fitting

from the expansion tank to the fitting in one of the

sleeves (Figure 1).

4. Connect another length of air line from the remaining

1/2” air fitting from the expansion tank to the fitting in

the other sleeve (Figure 1).

5. Attach the 1/4” air line from the existing tee for the

manual fill valve to the elbow on the expansion

tank (Figure 1).

6. Turn the key on and let the suspension resume ride

height. Check for leaks.
