Product Details

The ACDelco 42842336 Rear Coil Spring Lower Insulator is a genuine GM replacement component designed to cushion and isolate the coil spring from the vehicle's suspension mounting point. This insulator sits between the bottom of the rear coil spring and the suspension assembly, preventing metal-to-metal contact and reducing noise, vibration, and harshness (NVH) transmitted into the cabin.

Key Features:

  • Engineered to OEM specifications for precise fit and durability
  • Constructed from high-quality rubber or elastomeric material to absorb road shock
  • Prevents premature wear on coil springs and suspension components
  • Helps maintain proper spring alignment and positioning
  • Direct replacement for worn or damaged original insulators

Over time, coil spring insulators can deteriorate due to constant compression cycles, exposure to road debris, and temperature fluctuations. Replacing worn insulators restores proper suspension function, eliminates clunking or rattling noises, and ensures optimal ride quality. This ACDelco part meets General Motors' strict quality standards for reliable performance and long service life.

GREAT NO PROBLEMS!!!!

Work great match with good and with good instructions

Great price,Very fast shipping,Will buy from them again!!

The casing on the speaker was broken, but I did have another casing to use. You only had one available, and I couldn't find it anywhere else, so I chose not to return it.

Great Experience! Will buy from again!

Thanks

The ability to be able to track the package was not very good. No kind of order feedback available other than speaking with customer service.
