Weld on Steering Pinion Couplers

We offer two types of weldable splined couplers to achieve a proper and secure connection between a steering shaft or drive unit to the steering box for the 9/16-26 Spline (when a U-joint is not desired).

The splines in these couplers are precision broached to the correct size. We inspect and test fit each part 100% - we guarantee they will fit their intended purpose.

Split-Bolt coupler:

C42-354
Spline is correctly sized to fit the Stiletto Pro-box, Stiletto Gen 5 Small Box (C42-348 series), and Pinto OEM style rack
Machined from 1018 mild steel

The Split-Bolt design provides positive clamping on the splines, plus the added security of the bolt passing thru the retaining groove of the pinion. When space or weight savings is a primary concern, the Dual-Lock coupler is another option to consider.

Dual-Lock coupler:

C42-403
Spline is correctly sized to fit the Stiletto Pro-Box, Stiletto Gen 5 Small Box (C42-348 series), and Pinto OEM style rack
Machined from 4130N Chromoly

The Dual-Lock coupler has two set screws with locking nuts offset 90 degrees from each other. This dual set screw design draws up the connection thereby eliminating the potential of undesirable lost motion with normal spline clearance. To prevent spline deformation the locking screws are positioned to locate in the external retaining groove of the pinion.
