Two front complete strut and coil spring assemblies for 2006–2011 Buick Lucerne and 2006–2011 Cadillac DTS.
Critical fitment warning: The source does not specify compatibility with electronic suspension, active or continuously variable damping, magnetic ride systems, automatic leveling, specific RPO codes, engine, trim, wheel package, or production-date breakpoints. Confirm the VIN, suspension RPO codes, electrical connectors, original front strut configuration, spring shape, mounting points, and reference number before ordering.
Vehicle Compatibility
- 2006–2011 Buick Lucerne
- 2006–2011 Cadillac DTS
Electronic or active-suspension compatibility is not confirmed. Vehicle year and model alone are not sufficient for final verification.
Reference Numbers
172321, SR4211, 182321.
The source repeats some references but does not explain their relationship or assign them to left and right sides. Match both original front assemblies, connectors, mounting points, and suspension RPO codes.
Package Contents
- 2 front complete strut and coil spring assemblies
The source explicitly identifies complete strut and coil spring assemblies but does not separately confirm the exact count or design of upper mounts, mount bearings, spring seats, isolators, bump stops, dust boots, electronic connectors, resistors, nuts, or other hardware. Review the product images and compare both assemblies with the original units.
Common Strut Symptoms
- Excessive bouncing, pitching, or body movement
- Knocking or clunking from the front suspension
- Fluid leakage from a strut
- Uneven tire wear or reduced steering stability
- Suspension warning message on electronically controlled systems
Similar symptoms may be caused by control arms, ball joints, sway-bar links, tie rods, wheel bearings, tires, wiring, ride-height sensors, or suspension-control components. Diagnose the complete system before replacement.
Installation Notes
Suspension work is safety-critical; professional diagnosis and installation are strongly recommended. Before removal, identify the vehicle’s suspension RPO codes and inspect each original strut for electrical connectors or active-damping components. Compare left/right mounting points and brake-hose or ABS-wire brackets. Inspect the steering knuckles, control arms, ball joints, tie rods, sway-bar links, sensors, wiring, and related fasteners. Follow GM torque specifications and service procedures. Do not loosen the center shaft nut or disassemble a loaded spring assembly without the correct spring-compression equipment. After installation, verify all routing and clearances, check for suspension warnings, road-test cautiously, and complete a four-wheel alignment.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.
