Description

This comprehensive kit ensures a proper fit and reliable performance, meeting or exceeding OE specifications. Constructed for durability, the axle features 31 splines and a length of 34.35 inches, utilizing 14mm studs. The advanced heat-treatment process applied to this axle significantly enhances its strength and longevity, making it a robust replacement or upgrade component. The kit is designed for ZF 12-bolt rear axles with a 5-lug pattern and is configured for left-hand (LH) operation. Included with the ZA K630814 kit are all the necessary components for installation, such as a wheel bearing, seal, differential cover gasket, studs, and lug nuts. This ensures that you have everything required to complete the job efficiently.
