3R90-271 – Cv Double Joints Heads – Butt Dia 2.625″ – Tube Dia Wall 2.750X0.065 – End To Weld 11.75

The 3R90-271 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 3R90-271 CV double joint head requires exact pilot diameter and bolt circle to seat correctly on the axle or diff flange.

3R90-271 Cv Double Joint Head — Series: 3R CV MID SLIP. Bolt Circle & Pilot Specs

Series: 3R CV MID SLIP. The 3R90-271 CV double joint head specs: 0 bolt circle | 0 pilot | 2.625" butt dia | 11.75" end-to-weld. 3R MID SLIP CV STYLE. 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 3R90-271 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.
