5373 – Increase Bushing – Length 875″ – From Tube 35-083 – Inside Dia 3.338″ – Outer Dia 4″

5373 Increase Bushing 35-083 to 4-083

The 5373 is a driveshaft increase bushing transitioning from a 35-083 tube (3.5" OD x 0.083" wall) to a 4-083 tube (4.0" OD x 0.083" wall). Inside diameter is 3.338", outer diameter is 4.0", and length is 0.875".

Specifications

• Part Number: 5373
• From Tube: 35-083
• To Tube: 4-083
• Inside Diameter: 3.338"
• Outer Diameter: 4.0"
• Length: 0.875"

When fitting the 5373, confirm the inner tube is 3.5" OD x 0.083" wall (35-083) and the target outer tube is 4.0" OD x 0.083" wall (4-083). The 3.338" ID accommodates the 35-083 inner tube bore. Both tubes use the same 0.083" wall specification. Confirm the tube ends are cut square and deburred before insertion.

The 5373 is one of the larger-diameter increase bushings in this series, transitioning from the 3.5" to the 4.0" tube family, both at 0.083" wall. This applies to heavy-duty driveshaft builds where a large-diameter tube step is required. A heavier-wall tube will prevent the bushing from seating at the correct depth.

The 5373 ID of 3.338" and OD of 4.0" are the critical matching dimensions. Verify both tube specs (35-083 inner and 4-083 outer) before ordering. The 0.875" length and resulting weld land must be sufficient for the weld procedure specified for these tube dimensions.
