A joint solution to suit all vehicle types
In most applications, the inboard CV Joint is a plunge joint that allows the effective length of the sideshaft to change due to suspension travel. In front (or steer) axle applications, the outboard joint must transfer torque effectively through a wide angle (up to 52 degrees). In rear axle applications, joint operating angles are much lower.
GKN Driveline joint kits contain all the individual parts needed for professional repairs: joint, boot, boot circlips, tightening straps, bolts, nuts, spacers, etc.

Fixed Ball (AC) Joint
The AC joint is suitable for passenger cars and light vehicles. Providing a maximum articulation angle of 47 degrees to meet the criteria for steering and suspension movement, it is the most popular choice for the wheelside of a constant velocity sideshaft.
Fixed Ball (UF) Joint
Offering the same strength and durability as the AC joint, the UF fixed ball joint provides the maximum 50 degrees articulation angle, so affording greater latitude in the design of the steering geometry and facilitating smaller turning circles.
Fixed Ball Joint – SIO plus Ballspline
The SIO joint for inboard use is based in the “opposed track” principle to provide high performance in smallest packaging with optimised joint efficiency. Together with the ballspline as plunging unit, it represents a premium solution for extreme plunge angle requirements and high installation angles, as for instance needed for SUV vehicles.
CV joints connect the drivetrain and transfer the torque. Front-wheel drive vehicles generally have two CV joints, connecting the sideshafts to the front wheels. All-wheel drive vehicles with more complex layouts can have up to seven. And they must function under rotation, articulation and axial displacement to allow the vehicle’s suspension to move and the wheels to steer. For decades the standard solution for fixed CV joints has been the Rzeppa CV joint, a well proven concept that uses balls to transfer the torque between ball races. Rzeppa joints provide effective articulation up to 47°, but at higher installation angles its sphere forces can generate heat, significantly reducing the joint’s efficiency.
Tripod Plunging (GI) Joint
The standard tripod joint GI is suitable for the inboard gearbox joint of a constant velocity sideshaft for most vehicles. It has a maximum articulation angle of 23 degrees and has a plunge length of 50mm. It is ideal for medium working angles and its low plunge resistance aids good NVH characteristics.
Tripod Plunging (AAR) Joint
In addition to the properties of the GI joint, the low plunging resistance and low axial forces of the AAR joint deliver additional NVH refinement, making it appropriate for high working angles. It has a maximum articulation angle of 26 degrees and 50mm plunge.
Ball Plunging (VL) Joint
The VL ball plunging joint is a popular choice for the inboard joint of the rear-wheel drive CVJ sideshafts. With maximum 22 degrees articulation and a plunge of 50mm it is ideal for high working angles with low axial forces. The VL joint is also available as monobloc or disc version.
Ball Plunging (DO) Joint
The DO joint is similar to the VL. It is available in two versions with 50mm plunge for a maximum articulation of 26 degrees or 31 degrees. The DO joint is also suitable for high working angles on account of the low axial vibration.
