Corvette Stingray C7 steering gear from ZF

steering gear for the C7 Corvette is a critical inventory item. While many identify these as ZF units (due to ZF’s acquisition of the original manufacturer, ZF Lenksysteme), they are now officially serviced and branded through Bosch Automotive or GM/ACDelco.

1. Technical Evolution: ZF to Bosch

The C7 uses a Variable-Ratio Electric Power Steering (EPS) rack. Originally a joint venture between ZF and Bosch (ZF Lenksysteme), Bosch took full ownership in 2015.

• Early Models (2014–2016): Often carry the older ZF-derived part numbers.

• Late Models (2017–2019): Branded as Bosch. These are physically interchangeable but often feature updated internal motor software for better heat management during track use.

2. Key Part Numbers & Interchange

Because there are variations between the Base Stingray, Z51, and Z06/ZR1, part number accuracy is vital for your listings.
