Pros: Smooth and progressive power assist, feels natural at all speeds; High-quality components with robust build, backed by good warranty
Cons: Premium price point, may be overkill for lighter builds
2. Unisteer Rack and Pinion EPS Kit: Best for Handling
The Unisteer Rack and Pinion EPS Kit is designed for hot rods that want to convert from a steering box to a modern rack-and-pinion setup with integrated electric assist. Based on our research, this kit offers excellent steering precision and a direct feel. It comes with a pre-assembled rack, motor, control module, and necessary hardware. Owner feedback highlights the improved handling and reduced steering effort, especially at low speeds.
That said, this is not a simple bolt-on. Installation requires cutting and welding crossmembers, and the kit is vehicle-specific. It also costs significantly more than column-mount options. If you are building a dedicated performance hot rod and are comfortable with fabrication, this kit delivers top-tier handling. For a simpler cruiser, the added complexity may not be worth it.
- Rack-and-pinion design improves steering precision over traditional steering boxes
- Integrated EPS motor provides assist directly at the rack
- Includes mounting brackets, tie rods, and steering shaft coupler
Pros: Significantly improves steering response and reduces play; Complete kit includes everything needed for conversion
Cons: Requires more fabrication and welding than column-mount kits
3. Ididit EPS Column Kit: Best Column Kit
The Ididit EPS Column Kit is a complete steering column with a built-in electric power steering motor. We evaluated it as one of the easiest EPS solutions for hot rods because it replaces the entire column. The kit includes a tilt mechanism and a collapsible shaft, which are safety advantages. Owner reviews consistently praise the straightforward installation and the natural steering feel. The control module offers adjustable assist, and the wiring harness is well-labeled.
However, this kit is designed for vehicles that accept a GM-style column, so it may not fit all hot rods without modification. The assist level is adequate for most cars, but some owners with heavier front ends report wanting more power. If you have a standard chassis and want a simple, clean installation, this is a great option. For custom builds with unique steering geometry, other kits may be more adaptable.
- All-in-one steering column with integrated electric power steering
- Tilt feature and collapsible design for safety and comfort
- Includes wiring harness, control module, and mounting hardware
Pros: Simplest installation: replace entire column and plug in; Tilt and collapsible features add safety and ergonomics
Cons: Limited to vehicles that accept a standard GM-style column
4. Rebel Racing Electric Power Steering Kit: Budget Pick
Rebel Racing offers a budget-friendly universal EPS kit that we researched as a solid value option. It features a 1.5 kW motor and a compact controller, making it easy to mount on most columns. Owner feedback indicates that it works well for lighter hot rods (under 2,800 lbs) and reduces steering effort significantly. The kit includes basic wiring instructions, and many users reported a successful installation with minimal fabrication.
However, the lower power output means it may not provide enough assist for heavier cars or those with wide, sticky tires. Some owners noted that the assist can feel inconsistent at low speeds. Durability concerns were also mentioned, with a few reports of controller failure after extended use. If you have a lightweight hot rod and are on a tight budget, this kit is worth considering, but for heavier builds or long-term reliability, we recommend stepping up to a more robust option.
- Universal design fits most steering columns with 3/4-inch shaft
- 1.5 kW motor suitable for vehicles up to 2,800 lbs
- Compact controller with three assist settings
Pros: Affordable entry into EPS for budget builds; Compact motor fits in tight spaces
Cons: Lower power may struggle with heavier cars or large tires
5. Kugel Komponents Electric Power Steering Kit: Custom Fit
Kugel Komponents offers a modular EPS system that we found is best suited for experienced builders. The motor and controller are separate, allowing custom mounting in tight or unusual chassis layouts. The components are well-made, and the company is known for hot rod parts. Owner feedback from advanced builders reports excellent performance once properly set up, with smooth assist and good reliability.
However, this is not a kit for the faint of heart. There is no universal mounting bracket or wiring harness; you must design and fabricate everything. The cost can also add up quickly when buying separate parts. If you are building a one-off custom hot rod and have fabrication skills, this kit offers flexibility that others don’t. For most builders, a more complete kit will save time and frustration.
- Motor and controller sold separately for flexible mounting
- Designed for custom chassis and fabricated steering systems
- High-quality components from a respected hot rod parts manufacturer
Pros: Allows custom placement of motor and controller; Strong build quality and support from a specialty manufacturer
Cons: Requires significant fabrication and engineering skill
6. American Powertrain EPS Kit: Integrated System
American Powertrain’s EPS kit integrates power assist into a quick-ratio steering box, designed for hot rods that want to keep the classic appearance. Based on our research, it offers a good blend of modern function and traditional form. Owner feedback indicates that it reduces steering effort noticeably and provides a sportier feel thanks to the 12:1 ratio. The kit includes necessary hardware for installation.
However, this kit is only compatible with vehicles that have a steering box mount, so it won’t work with rack-and-pinion setups. Some users reported that the assist can be inconsistent at very low speeds, and the quick ratio may feel twitchy on the highway for some drivers. If you want to keep your original steering box location and prefer a quicker ratio, this is a decent option, but for a more refined experience, a column-mount EPS might be better.
- Replaces steering box with integrated EPS unit
- Quick-ratio (12:1) for faster steering response
- Includes steering shaft and coupler
Pros: Retains traditional steering box look with modern assist; Quick ratio improves handling feel
Cons: Limited to vehicles with a steering box mount
7. Speedway Motors Universal EPS Column Kit: Entry Level
Speedway Motors offers a basic universal EPS kit that we evaluated as an entry-level solution. It uses a 1.2 kW motor and a simple controller that only turns the assist on or off. Owner feedback from budget builders indicates that it does reduce steering effort, but the assist level is fixed and may feel too strong or too weak depending on driving conditions. The motor is compact and fits most columns.
However, this kit has the lowest power output and lacks adjustability, which can be a significant limitation. Some users reported that the assist cuts out at higher speeds, and the controller can be prone to overheating in hot weather. Durability is a concern, with several reports of motor failure after a year. If you have a very light hot rod (under 2,200 lbs) and want the cheapest EPS option, this might work, but we advise most builders to invest in a more capable kit for reliability and performance.
- Lowest-cost EPS option, universal fit for 3/4-inch shafts
- 1.2 kW motor provides basic assist for light cars
- Simple on/off controller without adjustable assist
Pros: Very affordable, good for tight budgets; Simple installation with basic tools
Cons: Limited power and no adjustability
Frequently Asked Questions
Can I install an electric power steering kit myself?
Many EPS kits are designed for DIY installation, especially column-mounted units that replace the existing column. However, some kits require welding, fabrication, and wiring expertise. We recommend reading the installation instructions before purchase. If you are not comfortable with automotive electrical systems or fabrication, professional installation is advisable.
How do I choose the right EPS kit for my hot rod?
Consider your vehicle’s weight, front-end layout, and your skill level. Column-mounted kits are simpler and cheaper, while rack-and-pinion kits offer better handling but require more work. Also consider the motor power: heavier cars need more assist. Check owner forums for specific recommendations for your chassis.
Will an EPS kit work with my existing steering column?
Some kits are universal and can be added to your existing column, but many require a specific column diameter or spline count. Column replacement kits are the easiest if you are willing to change the entire column. Always verify compatibility before buying.
Are electric power steering kits safe?
Yes, when installed correctly. Most kits include safety features like torque sensors and fail-safe modes that disable assist if a fault is detected. However, improper installation can lead to steering issues. We recommend following the manufacturer’s instructions and having a professional inspect the installation.
Do I need to upgrade my alternator for an EPS kit?
EPS kits draw significant electrical current (typically 30-60 amps). Many hot rods have alternators rated for 60-100 amps, which may be sufficient. However, if your alternator is low-output or you have many electrical accessories, you may need to upgrade to a higher-output alternator to avoid voltage drops.
