RS Series Hangers

Hendrickson Truck

Component Charts

This RS Frame Hanger guide is intended to aid in the proper

identification of originally equipped RS drilled hangers and

heavy duty center hangers for retrofit in the aftermarket. It

lists common drill patterns and castings that were in use prior

to 1983, 1983 to 1990, and 1990 to date. On glider kit

installations, where Hendrickson did not have control of

hanger usage, care should be taken in identification.

To use this guide, it is important to:

1. Identify the age of the vehicle

2. Measure the outside to outside frame width

3. Obtain the cast part number, and

4. Identify the truck manufacturer

To assist further, we have listed for your reference, the hole

diameters and the distance from the bottom of the frame to

the first line of holes.

In some cases, where the manufacturer changed drill patterns,

but still used the same casting number, we have tried to list

the date of this changeover. Hole location dimensions should

be used always as a final check.

For any casting number not shown or truck manufacturer not

listed, contact our Technical Service Department.

Frame Hanger Design

The RS Series suspensions use four rubber load cushions.

Each cushion has an inner cross bar that helps support the

load when the vehicle is loaded. An empty vehicle is

supported only by the outer edges of the cushions.

Vertical Drive Pin

The frame hangers have vertical drive pins that extend

down through the load cushions and are secured to

rubber vertical drive cushions in the saddle.

A rebound control stop kit consisting of special stop nuts

and elastomer bumpers is available to increase stability in

high center of gravity or offset loading vehicles. It is

optional for 40,000 thru 48,000 lb. capacities and

standard on 52,000 lb. units.

Heavy Duty Kit

The heavy duty kit for increased stability consists of an

additional round center cushion and related bracket for

each side of the chassis. It is optional for 40,000 lb.

capacities and standard on 46,000 thru 52,000 lb. units.
