If the trailer / suspension was originally equipped with composite springs and replacement is
necessary, simply replace with another composite spring. However, if the vehicle is equipped with
steel springs and conversion to composite springs is desired to achieve weight savings, utilize the
following recommendations.
Converting Reyco 21B Steel Spring Suspensions to Composite Springs Using the
TRA076 Spring:
| 1. |
Composite springs can only be used in an over slung single or tandem application. |
| 2. |
Mounting heights are limited to a maximum of 17" for standard configurations, 16" for no-hop
configurations. |
| 3. |
Do not use fabricated top plate. Only the Flagg part number R117 cast top plate can be used. |
| 4. |
U-Bolt torque value is reduced to 250 ft.lbs. and must be achieved through a 50 ft.lbs. alternating
process. |
| 5. |
Composite springs CANNOT be used in conjunction with a heavy duty hanger option. |
Converting Transpro 86 and 88 Steel Spring Suspensions to Composite Springs
Using the TRA076 Spring:
| 1. |
Composite springs can only be used in an over slung single or tandem application. |
| 2. |
Mounting heights are limited to a maximum of 17" for standard configurations, 16" for no-hop
configurations. |
| 3. |
DO NOT use fabricated top plate. Only the Flagg part number R117 cast top plate can be used. |
| 4. |
A reinforced fabricated axle seat must be used. DO NOT use standard axle seats as spring failure
will result. |
| 5. |
U-Bolt torque value is reduced to 250 ft.lbs. and must be achieved through a 50 ft.lbs. alternating
process. |
