Apex Designs Power Steering Boost Kit Jeep JL / JLU / JT

Any time a Jeep is lifted with larger tires and higher offset wheels, the drag on the hydraulic power steering is greatly increased. Deflate your tires for off-road and it’s even worse. The stock system pressures are set low as it’s enough for 33” tires and stock wheels and helps prevent overheating of the system.

With aftermarket performance parts and harder use, the stock pressures and lack of cooling ability become an issue. We have found that the factory power steering is capable of running at a higher pressure with ease.

The boost kit allows for a retune of the factory blowoff valve so we can increase steering power by 40%. While this is good news, more power = more heat and the factory system was barely acceptable. This is why a power steering cooler is included. This boost kit MUST be used with a cooler to operate correctly.

WHAT DOES THE STEERING BOOST KIT FIX?
No more stalled steering when it’s sub-freezing temperatures.
Smooth steering in parking lots on hot days.
Proper steering feel while in sand dunes.
Less feedback from terrain inputs.
Easy steering while aired down.
Overall it feels like stock but no more steering issues regarding power.

HOW LARGE OF TIRES IS IT DESIGNED FOR?
It will work any size tire and have great improvements. A 39” tire is about the largest tire where most to all issues will be solved. With 40s you may see some sticking while aired down on high traction surfaces. It’s still a great improvement and with one of the many ram assists available, you will have all the power you need.
