RS5000X Product Line Details
The RS5000X line from Rancho is designed to deliver consistent suspension performance with durable construction. This product line focuses on providing extended travel shock absorbers that maintain vehicle stability and comfort under various driving conditions. The RS55287 shock absorber fits within this line by offering extended length and travel specifications suitable for Ford F-150 and Lincoln Mark LT models.
Technical Description and Features
The Rancho RS55287 shock absorber features an extended length of 30.59 inches and a compressed length of 18.43 inches, allowing for a travel length of 12.16 inches.
