Dial in ride height and original handling with the KYB Strut-Plus (KYB strut plus) complete strut and coil spring assembly, MPN SR4199 — a front right corner unit that installs as a direct-fit replacement for the 2007-2008 Dodge Nitro and 2002-2012 Jeep Liberty (see the Buyer's Guide tab for engine details). A strut assembly supports vehicle weight, determines ride height, acts as the steering pivot and helps control stability.
As a KYB front strut assembly, this pre-assembled corner combines strut, mount and spring for professional results with no separate spring compression. Among KYB complete struts, the Strut-Plus is designed to help restore factory ride height and handling. Sold as a single corner; for even, balanced ride it is best practice to replace both sides together.
