Product Description

The H&R 54601 Sport Lowering Springs are purpose-built for the first-generation Scion xA (2004-2006) and xB (2004-2007), both sharing the same NCP-platform architecture and spring application. These springs lower the front by approximately 1.5 inches and the rear by 1.3 inches, closing the fender gap and eliminating the stock ride height's excess body roll tendency. The result is a more planted, aggressive stance that looks intentional without the harshness of race-spec springs.

H&R's progressive spring rate design means the springs remain soft and compliant under normal driving loads, then firm up progressively as cornering forces increase - keeping the ride comfortable for daily commutes while delivering noticeably tighter handling on backroads or occasional track use. Each spring is formed from H&R's 54SiCr6 spring steel and shot-peened for longevity, then powder coated in H&R's signature blue finish for corrosion protection. The complete set of four springs is a direct drop-in for the factory shock absorbers, making installation straightforward with a professional alignment recommended after fitment.
