IC28 – Increase Bushing – From Tube 2-065 – Inside Dia 1.87″ – Outer Dia 2.5″ – To Tube 25-083

IC28 Increase Bushing 2-065 to 25-083

The IC28 is a driveshaft increase bushing transitioning from a 2-065 tube (2.0" OD x 0.065" wall) to a 25-083 tube (2.5" OD x 0.083" wall). Inside diameter is 1.87", outer diameter is 2.5".

Specifications

• Part Number: IC28
• From Tube: 2-065
• To Tube: 25-083
• Inside Diameter: 1.87"
• Outer Diameter: 2.5"

When fitting the IC28, confirm the inner tube is 2.0" OD x 0.065" wall (2-065) and the outer tube is 2.5" OD x 0.083" wall (25-083). The 1.87" ID accommodates the 2-065 tube with the 0.065" wall factored in. Confirm the tube is cut square and deburred before insertion.

The IC28 steps from a lighter-wall 2" tube to the standard 2.5" tube. The IC25 transitions from the same 2-065 inner tube but targets a 25-065 outer tube (also 0.065" wall). The IC28 differs because the target outer tube uses a heavier 0.083" wall (25-083). Confirm the outer tube wall spec (0.083") before ordering.

The IC28 ID of 1.87" and OD of 2.5" are the critical matching dimensions. Verify both tube specifications (2-065 inner, 25-083 outer) before ordering. Using IC25 (targets 25-065, 0.065" wall outer) in a 25-083 application will result in an OD fit discrepancy at the weld joint.
