The ICON 57872P is a 2.5-inch body remote reservoir shock sold as a pair, offering a larger oil volume, higher-performance remote reservoir design, and superior heat management for more demanding off-road and towing use. The 57872P is the premium option for users who prioritize maximum damping consistency and off-road capability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much lift does the ICON 56523 provide?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ICON 56523 is a shock absorber, not a lift spring. It is compatible with 0 to 3 inches of rear lift height and is designed to work with rear coil spring lift kits such as the ICON 52753. The shock itself does not add lift; the coil spring determines ride height.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the ICON 56523 require new rear coil springs?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ICON 56523 can be installed with factory rear coil springs. However, ICON recommends pairing the 56523 with ICON dual rate rear coil springs (52753) for the best performance and to achieve a lifted ride height. Upgraded springs and shocks together provide consistent valving and lift across the rear suspension.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a wheel alignment after installing the ICON 56523?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eReplacing only the rear shock absorbers generally does not affect front wheel alignment. If you also install rear lift springs at the same time, a full 4-wheel alignment is recommended to ensure proper tire wear and handling after the ride height change.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the ICON 56523 rebuildable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. ICON 56523 shocks are fully rebuildable. ICON offers rebuild kits and rebuild services to restore the shock to factory specification. Rebuilding is a cost-effective option for extending the life of the shock or retuning valving for different applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the ICON 56523 covered by warranty?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eICON Vehicle Dynamics backs its products with a limited lifetime warranty against defects in materials and workmanship for the original purchaser.
