APR SUS00021 Roll-Control Lowering Springs are engineered to improve the stance, handling, and driving feel of the 2019–2024 Volkswagen Jetta GLI while maintaining comfortable street manners. Designed for both DCC and non-DCC factory dampers, this direct plug-and-play upgrade lowers the vehicle’s center of gravity and increases spring rates to reduce body roll, improve cornering response, and create a more planted driving experience.
APR developed these springs through extensive street and track testing to achieve a balanced combination of performance and comfort. Unlike overly stiff lowering springs that can create a harsh, bouncy ride or cause frequent damper bottoming, the SUS00021 system uses carefully configured ride heights and spring rates to deliver sharper handling without sacrificing everyday drivability. The front and rear dual-rate springs operate as single-rate linear springs under normal loaded driving conditions, helping maintain consistent performance on the road.
Manufactured in the USA from high-tensile chrome silicon steel, APR SUS00021 springs resist sagging and failure for long-term durability. A red powder-coated finish helps protect the springs from corrosion and adds a distinctive appearance. The system lowers the front approximately 1.3 inches and the rear approximately 1.5 inches on DCC-equipped applications, although actual ride height may vary by vehicle. For enhanced handling, performance, and comfort, pair these springs with APR Bumpstops, part number SUS00025.
