5365 – Increase Bushing – Length 875″ – From Tube 35-156 – Inside Dia 3.188″ – Outer Dia 4″

5365 Increase Bushing 35-156 to 4-065

The 5365 is a driveshaft increase bushing transitioning from a 35-156 tube (3.5" OD x 0.156" wall) to a 4-065 tube (4.0" OD x 0.065" wall). Inside diameter is 3.188", outer diameter is 4.0", and length is 0.875".

Specifications

• Part Number: 5365
• From Tube: 35-156
• To Tube: 4-065
• Inside Diameter: 3.188"
• Outer Diameter: 4.0"
• Length: 0.875"

When fitting the 5365, confirm the inner tube is 3.5" OD x 0.156" wall (35-156) and the target outer tube is 4.0" OD x 0.065" wall (4-065). The 3.188" ID matches the 5366 (also from 35-156), but the 5365 has a smaller 4.0" OD targeting the 4-065 tube rather than the 4.5" OD of the 5366. Confirm the outer tube OD and wall spec before ordering.

The 5365 involves a significant wall thickness differential between inner (0.156") and outer (0.065") tubes. The outer 4-065 tube is notably thin-wall for a 4.0" application; weld parameters must be adjusted accordingly to avoid burn-through on the 0.065" wall. The 0.875" length provides the weld land on both tube interfaces.

The 5365 ID of 3.188" and OD of 4.0" are the critical matching dimensions. Both tube specifications (35-156 inner and 4-065 outer) must be verified before ordering. Do not substitute the 5366 (4.5" OD) when a 4.0" outer tube is required -- the OD is the defining fitment dimension for the outer tube interface.
