IC29 – Increase Bushing – From Tube 25-083 – Inside Dia 2.334″ – Outer Dia 3″ – To Tube 3-065

IC29 Increase Bushing 25-083 to 3-065

The IC29 is a driveshaft increase bushing transitioning from a 25-083 tube (2.5" OD x 0.083" wall) to a 3-065 tube (3.0" OD x 0.065" wall). Inside diameter is 2.334", outer diameter is 3.0". When installed, the bushing produces a 0.25" lip.

Specifications

• Part Number: IC29
• From Tube: 25-083
• To Tube: 3-065
• Inside Diameter: 2.334"
• Outer Diameter: 3.0"
• Notes: 0.25" LIP

When fitting the IC29, confirm the inner tube is 2.5" OD x 0.083" wall (25-083) and the target outer tube is 3.0" OD x 0.065" wall (3-065). The 2.334" ID is the same as the IC38 (also from 25-083) -- the difference is in the outer tube: the IC29 targets the 3-065 (0.065" wall) while the IC38 targets the 3-083 (0.083" wall). The 0.25" installed lip is normal for this bushing design.

The target tube in the IC29 is the thinner-wall 3-065 specification. The 3.0" OD of the bushing fits both 3-065 and 3-083 tubes (same OD, different wall), so the outer tube wall spec is the key differentiator. Confirm the outer tube wall before ordering.

The IC29 ID of 2.334" and OD of 3.0" are the critical matching dimensions. Verify both tube specifications (25-083 inner, 3-065 outer) and account for the 0.25" installed lip in the assembly length calculation. Do not interchange with the IC38 without confirming the outer tube wall specification.
