1. EPAS Performance Universal Electric Power Steering Kit: Top Pick
In our evaluation, the EPAS Performance Universal kit stands out for its balance of performance and adaptability. Based on owner feedback and the spec sheets, its speed-sensing assist provides a natural steering feel, adjusting the assist level dynamically with vehicle speed. The compact motor design is a significant advantage, often allowing for a relatively discreet installation within the vehicle’s interior.
A notable limitation for some users, however, is the potential need for custom fabrication or modifications to the steering column shaft, especially in vehicles with unique steering column designs. While its universal nature offers broad compatibility, it does not imply a direct bolt-on fit for every single classic. Owners seeking a completely direct fit without any cutting or welding should carefully verify their specific vehicle’s requirements against the kit’s design to avoid unexpected installation challenges.
- Universal design compatible with a wide range of classic car applications.
- Features a sophisticated control module offering speed-sensitive assist and adjustable settings.
- Engineered for compact installation, often fitting within the dashboard or under the seat.
Pros: Highly adaptable to various classic car models based on reported fitment.; Offers a customizable driving feel with multiple assist levels.; Known for smooth, consistent power delivery across different speeds.
Cons: Installation may require significant fabrication for some highly customized setups.; The control module, while advanced, adds complexity to wiring.
2. EZ Power Steering Universal Electric Power Steering Kit: Premium Choice
The EZ Power Steering Universal kit consistently receives positive feedback for its robust construction and dependable performance. Based on our research of manufacturer specifications, the high-torque motor is particularly effective for larger, heavier classic cars, providing ample assistance without feeling overboosted. The inclusion of an integrated fail-safe system is a significant safety feature, ensuring steering control is maintained even in the unlikely event of an electrical malfunction.
However, the primary consideration for potential buyers is the physical size of the motor unit. While designed for under-dash mounting, classic cars vary significantly in interior space. We recommend that owners with very compact dashboards or complex existing wiring harnesses meticulously measure available space and plan their installation to ensure adequate clearance and ease of access. Those prioritizing an absolutely minimalist under-dash footprint might find this unit requires more careful integration.
- Utilizes a high-torque electric motor for robust steering assist.
- Includes an integrated fail-safe system for enhanced operational safety.
- Designed for under-dash mounting, preserving the engine bay's original appearance.
Pros: Reputation for high-quality components and reliable performance.; The fail-safe mechanism provides peace of mind during operation.; Effective power assistance, even for heavier classic vehicles.

7. Ididit Electric Power Assist Column: Compact Retrofit
The Ididit Electric Power Assist Column offers a compact retrofit solution by integrating the EPS unit directly into a new steering column. In our evaluation of its design, this approach is beneficial for achieving a very clean, factory-like appearance within the interior, as there is no separate motor assembly to mount under the dash. The added tilt functionality is also a significant ergonomic upgrade for many classic car drivers.
However, a primary consideration, similar to other integrated column solutions, is the necessity of completely replacing the original steering column. This decision impacts the vehicle’s originality, which is a critical factor for some collectors and restorers. Furthermore, based on product specifications and owner feedback, the power assist level in these integrated units is often fixed or has very limited adjustability compared to standalone EPS kits with dedicated control modules. Drivers who desire highly customizable steering feel or speed-sensitive assist might find this system less versatile than other options.
- Integrates a compact electric power assist unit directly into a new steering column.
- Designed for a clean, factory-like appearance once installed.
- Offers a modern update with tilt steering functionality.
Pros: Provides a very clean, integrated look with minimal visible components.; Adds modern tilt functionality to classic vehicles.; Reduces installation complexity by combining components.
Cons: Requires full replacement of the original steering column, impacting originality.; Specific fitment for certain vehicle models can be limited.; The power assist level is typically fixed or minimally adjustable, lacking fine-tuning.
Frequently Asked Questions
What are the main benefits of an electric power steering kit over a hydraulic system for a classic car?
Electric power steering (EPS) kits offer several key advantages. They eliminate the need for a hydraulic pump, hoses, and fluid, simplifying the engine bay and removing potential leak points. This also reduces parasitic drag on the engine, potentially improving fuel efficiency and horsepower. EPS systems often feature adjustable assist levels and can be more compact, allowing for cleaner installation. They also typically require less maintenance compared to hydraulic systems.
Is an electric power steering kit a direct bolt-on installation for any classic car?
While many EPS kits are designed for universal application or specific classic car models, it is rarely a direct ‘bolt-on’ without any modification. Universal kits almost always require some degree of fabrication, such as cutting and welding the steering column shaft, or custom mounting brackets. Even vehicle-specific kits may require minor modifications due to variations in classic car manufacturing tolerances or previous modifications. Always review the manufacturer’s installation instructions and measure your vehicle’s specific dimensions before purchase.
Do electric power steering kits offer adjustable assist levels?
Many modern electric power steering kits, particularly those with a dedicated control module, do offer adjustable assist levels. This feature allows the driver to fine-tune the amount of steering assistance, ranging from lighter effort for parking and city driving to a firmer, more responsive feel for highway speeds. Some advanced systems also include speed-sensing technology that automatically adjusts assist based on vehicle speed, providing a more natural and consistent steering feel.
What happens if the electric power steering system fails while driving?
Reputable electric power steering kits are designed with safety in mind and typically include a fail-safe mode. In the event of a system malfunction or power loss, the EPS unit is designed to revert to manual steering. While the steering effort will significantly increase, similar to driving a classic car without any power steering, you will still maintain full mechanical control of the vehicle. This ensures that a complete loss of steering is highly unlikely.
Can I install an electric power steering kit myself, or do I need professional help?
The feasibility of DIY installation depends heavily on your mechanical skill level, familiarity with automotive wiring, and the specific kit chosen. Basic universal kits may require significant fabrication, including cutting and welding of the steering shaft, which demands specialized tools and expertise. Kits integrated into new steering columns simplify some aspects but still involve electrical wiring and column replacement. If you are not confident with complex automotive modifications and wiring, professional installation is strongly recommended to ensure proper function and safety.
