STEERING BOOST INSTALL INSTRUCTIONS
COOLER INSTALL INSTUCTIONS
NOTE RE: INSTRUCTIONS: Installation instructions for the boost kit and cooler are based on the most common engine options of the 3.6 and 2.0 turbo. The steering systems are the same on all models and that is what the instructions focus on.
BOOST VALVE INSTALLATION TIPS:
Kit includes: patent-pending steering boost valve, gauge & hardware [X02-04-002 includes redesigned cooler X02-01-002]
[Note: this product is not designed to address steering slop due to aluminum steering box issues]
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.
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.
We recommend you try the boost kit first on the 40 and larger crowd before adding other devices.
WHY DID WE DESIGN THE BOOST KIT?
We found there was no middle ground on power steering upgrades. It was all or nothing. Now there is something that’s more budget friendly, easier to install, and gets you 80% of the way to the big dog ram assists.

The absolute best upgrade for your lifted Jeep steering, it really boost's the steering power.
Had it on for a week now. Has definitely made steering at low speeds great. I’m running this on a JLURD 37’s with ball joint deletes and 2ton steering. It is having no issues. I will test this on our Moab trip. There is no binding like stock up against a curd.
Arrived in one day
Easy install (read instructions before starting)
This was installed on a 2022 Wrangler 392 and it has worked according to the claims. I was able to turn pretty easily with the front locker engaged.
Purchased for a new JL diesel with 37’s and was having a hard time steering during off road conditions. Now I with the Boost Kit it’s effortless and simple.
