Product Details

The KYB Excel-G line is built on the same KYB OE assembly lines used for original equipment production and uses OE-quality components calibrated to restore factory-style performance rather than change it. Part number 343139 is designed for rear suspension service on classic Chrysler Fifth Avenue, Imperial, New Yorker, Town & Country, LeBaron, Newport, and select Dodge Aspen, Magnum, Charger, and Monaco models. This part cross-references Monroe Shocks & Struts 5837 for the same application.

For buyers searching for a rear shock absorber for 1979-1982 Chrysler New Yorker, a KYB Excel-G rear shock for 1983-1989 Chrysler Fifth Avenue, or a replacement shock for 1977-1978 Dodge Monaco rear suspension, 343139 provides an OE-style solution focused on restoring original ride behavior.
