IC38 – Increase Bushing – Length 0.8″ – From Tube 25-083 – Inside Dia 2.334″ – Outer Dia 3″

IC38 Increase Bushing 25-083 to 3-083

The IC38 is a driveshaft increase bushing transitioning from a 25-083 tube (2.5" OD x 0.083" wall) to a 3-083 tube (3.0" OD x 0.083" wall). Inside diameter is 2.334", outer diameter is 3.0", and installed length is 0.8". When installed, the bushing produces a 0.25" lip overlap.

Specifications

• Part Number: IC38
• From Tube: 25-083
• To Tube: 3-083
• Inside Diameter: 2.334"
• Outer Diameter: 3.0"
• Length: 0.8"
• Notes: 0.25" lip when installed

When fitting the IC38, confirm the existing driveshaft tube OD is 2.5" with a 0.083" wall (25-083) and the target tube is 3.0" OD x 0.083" wall (3-083). The 2.334" ID accepts the 25-083 tube end with the 0.083" wall factored in. Verify the tube end is cut square and deburred before insertion. The 0.25" lip produced when installed must be accounted for in the overall assembly length.

The IC38 steps from the common 2.5" to 3.0" OD, both at 0.083" wall. A heavier wall (0.095") will reduce the ID clearance and prevent the bushing from seating correctly. Confirm both tube wall thicknesses before ordering.

The IC38 ID of 2.334" and OD of 3.0" are the critical matching dimensions. The 0.25" installed lip and 0.8" length must be factored into the assembly geometry. Verify both tube specs (25-083 inner and 3-083 outer) before ordering the IC38.
