Regarding the design of the gasket on the bolt, the difference in the contact surface of the hub is taken into account. At the same time, accurate data such as the curvature and radius of the contact surface of the hub also need to be measured and calculated. BONOSS hopes to provide high-precision products to obtain consumer choice by designing every product detail. . The contact surface of the gasket requires the customer or store to provide the corresponding original model and whether the modified wheel hub is used, and the salesperson provides the corresponding product through communication.
The ball and conical seat bolts can be selected according to the stock bolt seat. In addition, different lengths also can be selected (28/37/45mm) in case of installing the wheel spacers. We are proud that the product pass ISO 10.9 Grade standard, Tensile Strength over 1100 MPA, tested by authoritative third-party SGS certification. BONOSS focuses on the best quality for every customer.
