RT/RU Series Hangers

Hendrickson Truck

Design This will assist in the identification of machined spring hangers for vehicles that have the RT/RTE/RU/RUE/U/UE suspensions.

By identifying the hanger design (as shown on the left) and the casting number from the hanger, the available spring hanger part numbers are shown. If your hanger is not listed or no casting number can be found the following is required for our identification: 1. Design 2. Frame Widths (Is there a spacer between spring hanger and frame?) 3. Hole Pattern Dimensions 4. Spring Pin Diameter

Hendrickson Truck Component Charts

Clamp Design Bolts inboard of the frame rail. No holes in the lower frame flange.

Flange Design Bolts through the frame lower flange. (Do not use on high tensile steel frames.)

Web Design Bolts into frame web only.

Hole Pattern Dimensions (Chart Below)

Frame Widths Standard width of rear tandem drive axles have a beam hanger spacing of 35 ⁷⁄₈ ". * To maintain the correct alignment of frame and axle, spring hanger offsets vary with chassis frame widths. ** (as shown below)

NOTE: For clamp and web mount spring hangers Hendrickson recommends a minimum " Grade 8 bolt with Grade C locknut and hardened washers be used to attach spring hangers to the main frame of the vehicle. With older model vehicles this may require that the holes in the frame be enlarged to accommodate the " fasteners. Refer to Technical Publications covering the RT/RTE or U/UE Series suspensions for proper installation.
