Product Details
AST Lowering Springs for the 1997-2004 BMW 5 Series 520i/523i/525i/530i/520D/525TDS Touring RWD (E39) are manufactured from a premium high tensile chromium-silicone wire which is handpicked by AST engineers for its quality and metal consistency.
Each spring is cold wound and then heat treated to increase hardness and reduce internal stresses present after winding. Each spring is then individually shot peened, phosphate treated and then powder coated to outlast even the life of the vehicle.
Standard Features
- Progressive rates on most vehicles.
- EDC Compatible (if applicable to vehicle)
- Each spring is blocked and computer tested prior to shipping, which reduces any settling once installed on the vehicle.
- Lifetime warranty on breaking.
- Most of our spring applications are TUV Certified and certificates can be provided upon request.
