3190-107 – Cv Double Joints Heads – CVJ Series – Butt Dia 1.571″ – Pilot Dia 4.094

The 3190-107 CV double joint head is the flange-side assembly for constant velocity driveshafts operating at steep angles — SAS builds, long travel suspensions, transfer case drop kits. It provides the ball socket centering mechanism that prevents velocity variation through the joint's full operating range. The 3190-107 CV double joint head requires exact pilot diameter and bolt circle to seat correctly on the axle or diff flange.

3190-107 Cv Double Joint Head — Series: CVJ. Bolt Circle & Pilot Specs

Series: CVJ. The 3190-107 CV double joint head specs: 3.583 bolt circle | 4.094 pilot | 1.571" butt dia | 4.75" end-to-weld. Fits 97-98 Ford Ranger/Explorer at transfer case. Pilot diameter is critical for the centering ball mechanism — a loose pilot allows the CV head to walk off-center at high angles, which defeats the entire purpose of the CV design. End-to-weld factors into compressed driveshaft length calculations.

Before ordering the 3190-107 CV double joint head, measure your existing flange bolt circle and pilot in millimeters or decimal inches. European and Toyota flanges vary by year and application — spec sheet data isn't always reliable on swapped or modified vehicles. Measure the actual flange.
