Frequently Asked Questions
Is this the right coil spring insulator for a 2011-2013 Ram 2500?
Yes. It is listed for the 2011-2013 Ram 2500, and also for the 2011-2018 Ram 1500 and 1994-2010 Dodge Ram 1500. See the "Vehicles it fits" section for the full list.
What does a coil spring insulator do?
It sits at the front upper spring seat, between the coil spring and the chassis. It helps control vibration traveling from the spring into the chassis.
What are the dimensions and material of CSI81246PR?
It is a round, black rubber insulator. It has a 155 mm outside diameter, an 89 mm inside diameter and a 10 mm thickness.
Is mounting hardware included?
No. The package contains one insulator and no mounting hardware. Quantity per application varies by vehicle, so check the "Vehicles it fits" section.
What are the signs of a worn coil spring insulator?
Squeaks, creaks or clunks from the spring area over bumps, or a cracked or flattened insulator, may mean it needs replacing. Diagnose the cause first, because other suspension parts can make similar noises.
