Lamborghini HURACAN steering gear 4S1423050G

The Lamborghini part number 4S1423050G refers to the Steering Gear (Steering Rack) assembly specifically designed for the Lamborghini Huracán and its platform sibling, the Audi R8 (Type 4S).

Here is a breakdown of the technical details and compatibility for this part:

Part Overview

• Part Number: 4S1423050G

• Component: Steering Rack / Steering Gear Box

• Type: Electric Power Steering (EPS) / Rack and Pinion

• Orientation: Left-Hand Drive (LHD)

  • Note: Right-Hand Drive (RHD) versions typically start with “4S2”.

Compatibility

This specific revision (“G”) is part of a series of updates for the Huracán steering system. While “G” is a common factory-fitted part, it is often superseded by or interchangeable with other letters in the sequence (such as 4S1423050L or 4S1423050K) depending on the production year and specific sub-model. It is found in:

• Lamborghini Huracán: LP610-4, LP580-2, Performante, and EVO.

• Audi R8 (4S): 2015–Present models.

Key Technical Specs

• Operating Mode: Electric. Unlike the Gallardo, the Huracán uses an electromechanical steering system.

• Dynamic Steering: Some versions of this rack are compatible with Lamborghini’s LDS (Lamborghini Dynamic Steering) system, which varies the steering ratio based on speed and driving mode.

• Included Components: Typically includes the main rack housing and internal tie rods, but may not include the outer tie rod ends or the electronic control module unless purchased as a complete “kit.”

Pricing and Availability

• New OEM: Expect to pay between $8,000 and $11,000 from authorized dealers or specialty parts suppliers like Scuderia Car Parts or Eurospares.

• Used/Refurbished: Used units typically range from $2,500 to $4,500 depending on mileage and condition.

Pro Tip: If you are replacing this due to a mechanical failure or accident, ensure your technician can perform the necessary software adaptation/calibration. Because this is an electronic rack, the car’s ECU must be “taught” the end-stops and centering of the new unit.
