With aftermarket performance parts and harder offroad 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 Apex 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. Customers who purchase the standalone kit are responsible for installing a compatible cooler. Overall it feels like stock but no more steering issues regarding power. [Note: this product is not designed to address steering slop due to aluminum steering box issues]
