The Eibach Pro-Kit (part 38103.140) is a set of four performance lowering springs, two front and two rear, made for the Pontiac G6, Saturn Aura and Chevrolet Malibu. It is a street-focused replacement for the factory springs. The manufacturer positions the Pro-Kit as an upgrade for daily drivers who want a lower stance and sharper handling without the harsh ride of a competition coilover. Compared with a budget spring, the Pro-Kit's main advantage is Eibach's engineering and quality control, and the manufacturer's stated guidance is to pair the springs with fresh or performance dampers for the best results. Shopping for an Eibach Pro-Kit for a 2008-2009 Malibu, a 2005-2010 G6 V6, or a 2007-2009 Aura? Confirm your exact year, engine and drivetrain against the manufacturer's application list before ordering.
Fitment matters here. The manufacturer's application selector lists the G6 with the 3.5L V6 (convertibles excluded) and the Aura with the 3.6L V6, and the manufacturer notes the kit does not apply to 4WD vehicles. Malibu year coverage varies between sources, so check your VIN before buying. Because the springs change ride height and geometry, the manufacturer advises a wheel alignment after installation, and it recommends replacing worn factory shocks or struts, or fitting sport dampers, when lowering springs are installed. Owners on user forums commonly describe the swap as a driveway job for someone comfortable with coil spring compressors, but the manufacturer recommends professional installation with proper tools.
No. The manufacturer's application listing excludes Pontiac G6 convertibles, and the manufacturer also states the springs are not for vehicles with 4WD.
Yes, the manufacturer recommends checking wheel alignment after any spring or suspension installation, because ride height changes alter camber, toe and caster settings.
The manufacturer recommends replacing worn factory dampers with new standard or sport shocks when using lowering springs. Its guidance notes that worn OE dampers can need replacement from roughly 40,000 km of use, and that sport dampers are recommended.
The manufacturer recommends installation by a qualified workshop with skilled technicians and the required special tools, so a spring compressor is essential for safe removal of the factory springs. Match each spring to its position by reading the imprint on the spring, as the manufacturer instructs. Plan for a wheel alignment immediately after the job, and consider replacing the shocks or struts at the same time, since lowering springs place more load on the dampers.
