Construction & Design:

The Prothane Front Coil Spring Isolator is crafted from premium-grade polyurethane, a material known for its excellent durability and flexibility under stress. This robust construction ensures the isolator withstands harsh off-road conditions, temperature extremes, and exposure to dirt and moisture without degrading. The isolator’s design precisely matches the coil spring seat contours of Jeep Wrangler models from 1997 through 2006, guaranteeing a secure fit that prevents unwanted movement or shifting during suspension articulation.

Unlike traditional rubber isolators that can deteriorate quickly, Prothane’s polyurethane formula offers enhanced resistance to cracking and compression set, providing consistent performance over the life of the vehicle. The vibrant red color not only identifies the part as a Prothane product but also adds a subtle visual upgrade under the hood.

Installation & Fitment:

Installation of the Prothane Front Coil Spring Isolator is straightforward and requires no special tools or modifications. The isolator simply fits onto the top of the front coil spring seat, acting as a cushion between the spring and the vehicle’s chassis. This direct-fit design ensures a secure and stable placement, allowing for quick replacement during routine suspension maintenance or upgrades.

This part is compatible with a wide range of Jeep Wrangler models, including the 65th Anniversary Edition (2006), Rubicon (2003–2006), Sahara (1997–2004), SE (1997–2006), Sport (1997–2006), Unlimited (2004–2006), Unlimited Rubicon (2005–2006), and X (2002–2006).
