Prothane 1-1703-BL Front Coil Spring Isolator Kit 1.5" and 2" Lift Black - Pair

The Prothane 1-1703-BL is a front coil spring isolator kit engineered for Jeep Wrangler TJ and JK models running a 1.5" front and 2" rear lift. Sold as a pair, these lift-height isolators are precision-molded from premium-grade polyurethane — a significant upgrade over the factory rubber pads that degrade under the constant stress of off-road use.

Key Features:

• Lift-Specific Design: Thicker than standard-height isolators, purpose-built to compensate for a 1.5" front / 2" rear lifted ride without requiring larger replacement springs
• Premium Polyurethane Construction: Far more durable than OEM rubber, polyurethane resists compression set, road salts, chemicals, and UV degradation for a longer service life
• Black Colorway with Graphite Additive: The black formulation includes a small amount of graphite blended into the polyurethane, which helps minimize squeaking during operation
• Precision Fabrication: Molded to exact OEM dimensions for a drop-in fit with no trimming or modification required
• Reduces NVH: Isolates the coil spring from the control arm, dampening road vibration and protecting suspension components from metal-on-metal contact
• Includes Pre-Lube: Kit ships with Prothane's super grease for proper lubrication at installation, ensuring quiet, long-lasting performance
• Lifetime Warranty: Backed by Prothane's lifetime warranty against defects in materials and workmanship for the original purchaser

This kit is the ideal solution for off-road enthusiasts who want to address worn or rotted OEM coil spring insulators while maintaining their existing lift setup. Available in black (1-1703-BL) or red (1-1703) to match personal preference — both colors share the same durometer hardness and performance characteristics.
