BMR SP640 lowering springs for V8-equipped 2002–2009 Trailblazer drop the front 2" and rear 3" while tuning spring rates for improved handling and a smoother ride. Each spring is computer tested, cold-wound from chrome-silicon high-tensile wire, compressed at the factory and stress-relieved at 750°F, then shot-peened to eliminate residual stresses. Springs are powder-coated red, backed by a lifetime warranty against sag, and are made in the USA.
