This special Aero boot fits Lobro CV joints with 108mm OD as used on some Formula 3000 and F1 cars. The bolt circle diameter is 94mm. The rubber portion has a simple taper to be lower-profile and more aerodynamic than the stock accordion-pleated boot, but it limits the maximum joint angle to approximately 6 degrees. Sold individually.
Note: We do not sell the matching 108mm joint. If you got your CV joint from us, you will need to use a 94mm OD CV Joint Boot, Part No. 1472.
