Prothane 19-1713 Universal Tie Rod End Boot Kit .550 x 1.438 in. Red Polyurethane Pair

The Prothane 19-1713 Universal Tie Rod End Boots are precision-molded polyurethane dust boots designed to protect tie rod end joints from dirt, sand, water, and snow. Sized at .550 in. shaft diameter x 1.438 in. rod end diameter, these boots are sold as a pair and offer a direct upgrade over factory rubber boots.

Constructed from premium-grade hi-tech polyurethane, these boots will not deteriorate from grease contact—a common failure point with OEM rubber boots. The result is superior lubrication retention, extended joint life, and improved steering feel. Precision fabrication ensures a secure, consistent fit across compatible applications.

Key Features:

• Premium polyurethane construction resists grease, oil, and environmental degradation
• Retains lubrication better than stock rubber boots for longer joint life
• Shaft diameter: .550 in. | Rod end diameter: 1.438 in.
• Provides necessary rigidity while holding grease for quiet, smooth operation
• Universal fitment — also fits 1979–1991 Mazda RX-7 ball joints
• Available in red (19-1713) or black (19-1713-BL)
• Sold as a pair

To select the correct size, measure the tie rod end at the largest diameter of the tapered shaft and at the diameter of the tie rod socket. Choose a boot that matches or is slightly smaller than those measurements for a proper seal.
