polybushings * com <<< go for the upgrade
Not only an upgrade, but also much cheaper. Dealer price is about USD 150.00 for the two uppers and two lowers in the front... Polybushings has a full set for front and back for 199: Also check, your uppers might still be ok, it is the lowes that really take a beating... Be aware they are somewhat of a PITA to replace. Quite time consuming...
from the polybushings website:
Polyurethane Coil Spring Isolators
Coil springs have a rubber seat or cushion, called isolators.
These are on the top and on the bottom of the coil springs.
The factory rubber ones wear out fast, being made of poly-foam.
These are made from suspension grade, solid polyurethane so they
will last for many years.
Fits 2nd generation from 1998 to 2004.
Dodge Intrepid, Chrysler 300M, Concorde, LHS, and New Yorker.
Kit part number PB1065
Price $199 plus Shipping ($10)
two upper front isolators

That is a total of all 8 isolators you need for the complete
