We offer two different types of boots to fit our 94mm OD Lobro-style CV joints (Part Nos. 1471 and 1473, sold separately). The bolt circle diameter is 78mm on both versions.
The Aero boot (shown at left in photograph) has no convolutions and is much more aerodynamic than the OEM bellows-style boot. The Aero boot limits the CV joint angularity to a maximum of approximately 6 degrees.
The Standard bellows-style boot (shown at right) is much more flexible, exceeding the joint's full 12 degrees of travel.
Note: The Aero version does not include any hardware or grease.
