This Borgeson OEM-style rag joint coupler connects a steering column to a steering box on applications where a factory flexible coupling was originally used. It is machined from steel and designed for installations with perfect alignment between the connecting shaft and steering box.
Specifications:
- Style: OEM rag joint (flexible coupling)
- Material: Steel
- Fitment: 18mm Double-D x 1"-48 spline
- Use: Straight-line connections only, perfect shaft-to-box alignment required
- Part Number: 055043
Not intended for applications with column-to-box misalignment; use a universal joint instead if angularity is present.
FAQ
What does a rag joint coupler do?
It is a flexible coupling that connects the steering column to the steering box, damping road vibration and noise while accommodating minor shaft flex, in applications where the column and box are in near-perfect alignment.
What sizes does this coupler fit?
This coupler fits an 18mm Double-D shaft on one side and a 1"-48 spline on the other.
Can this coupler be used where the column and box are misaligned?
No. Rag joint couplers are designed for straight, aligned connections only. A universal joint should be used if there is any angularity between the shaft and the steering box.
