3502-216 Flange Yoke 1350 Pilot: 2.162 Bolt Circle Diameter 3.937 Square Pattern Dodge

3502-216 Flange Yoke -- 1350 Series Torque Interface Component

At the interface between the driveshaft and the axle flange, dimensional accuracy defines whether the shaft runs straight or vibrates its way to an early failure. The 3502-216 is a 1350 series flange yoke ground to a 2.162" female (recessed) pilot that matches a 3.937" bolt circle companion flange. This combination delivers true, vibration-free rotation from the first mile, not just after break-in. Forged steel construction ensures the part endures the torsional shock loads that shock-absorber-equipped trucks and off-road builds generate during hard acceleration or abrupt stops.

Series Selection and Drivetrain Integrity

Running mixed series components -- a 1350 series flange yoke with a smaller or larger series u-joint -- is a common source of unexplained vibration and premature joint failure. The 3502-216 is engineered to be the termination point for a 1350 series shaft. The ear bores, the ear width, and the material grade all correspond to 1350 series loads. Install it with a 1350 series cross kit and proper grease packing for a drivetrain that performs at rated capacity.

Before You Install

• Degrease the pilot bore of the companion flange before seating the 2.162" pilot
• Inspect all 4 holes for thread condition -- chased threads hold torque better than corroded ones
• Use a flat-blade screwdriver to check companion flange face for warping -- a warped face will transfer vibration through even a perfect yoke
• Set CJ-to-flat at 1.625" -- the cross must not bottom out in the flange recess
• After installation, verify by rotating 360 degrees by hand before lowering off stands
