When you add heavy off-road modifications, such as aggressive suspension lifts and heavy, oversized 33\" to 37\" mud-terrain tires, the load on these joints multiplies exponentially. Over time, internal clearances open up, leading to loose steering tracking, premature tire wear, and harsh clunking or popping noises when navigating trail obstacles or potholes.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis original equipment manufacturer (OEM) kit refreshes your steering geometry with professional-grade, high-strength steel.
