Want to upgrade to Electric Hydraulic Power Steering? Here is everything you need.

“So, what do I need?” is one of the most common questions we get when people learn about the Hang Tight PSC through social media or from their friends. The concept of electric hydraulic power steering in your build is relatively new for most people, so we figured it’d be easier to lay it all out in a simple blog post. 

Here are all the parts required to upgrade or swap to electric hydraulic power steering for a majority of builds. Keep in mind, this is not an exhaustive list that covers every scenario. That’d be impossible, as we’ve seen some serious one off uses of our system. 

Hang Tight only carries the electrical controllers and controllers required, so we’ve broken it down into two sections.

Parts Available at Hang Tight

Flying Lead Harness

Unless you have experience crimping OEM style connectors, we highly recommend the flying lead option. Our team has all the correct tooling to ensure these connections are crimped correctly. All wire is TXL, loomed and heatshrink. 

Dodge EPAS Hydraulic Fitting

We’ve custom designed a straight and 90’ fitting specifically for the Dodge Pumps. This is a requirement when using a Dodge Pump for your build. Not sure what pumps you can use?

Potentiometer

The Hang Tight PSC can be controlled either with a potentiometer, or a PWM output on your aftermarket ECU. Our Potentiometers are motorsports grade and have a great feel. For simpler installations and quick changes, the potentiometer offers the fastest way to achieve this. If the PWM input fails for any reason, you can utilize a pot in conjunction with the PWM output as a failsafe.

Installation Accessories

Fittings

To complete the installation, you’ll need a few parts to connect either your steering rack or steering box to the pump. Depending on the pump, you’ll need to adapt the high pressure side of the pump to the high pressure side of your rack or steering box. Earlier in the article, we mentioned the proprietary Dodge high pressure fitting required. Both the Mazda and Volvo pumps use a Metric fitting M12x1.5mm. We suggest adapting that to a -6 AN line, similarly to our Dodge hydraulic fitting adapter. These can be found with most fitting supply companies. We recommend Redhorse, Radium Engineering or Vibrant for all your fitting needs.

Mechanical Power Steering Replacement Pulley

Choosing your replacement pulley is one of the more difficult parts of the process, and has many variables. Modern engines like the GM GenV (LT) platform don’t have mechanical hydraulic pump provisions, so that makes it fairly easy, but for older platforms, replacing the traditional pump in your serpentine belt can be a bit tricky. It’s definitely important to research this before doing the upgrade.

Mounting Solution

Correctly mounting electric hydraulic pumps is imperative to their performance and survival. If you’re sourcing your pump used, do your best to find pumps that retain the factory bracketry. Ensure you’re mounting them in the correct, factory orientation. It’s important to retain the rubber isolators in the brackets.

We suggest watching our installation video on Terence’s 1984 Oldsmobile Cutlass on YouTube. You can watch that below!

Tony Angelo from Stay Tuned Garage also did a great job installing the PSC in his LS swapped Porsche 911. You can check that out below.
