The adjustable control arms and heavy-duty track bar utilize Rancho’s proprietary D2 bushings, which are grease-free and self-centering to reduce maintenance needs and improve handling precision.

All mounting brackets and hardware are constructed from high-strength, low-alloy steel, ensuring long-term durability and resistance to corrosion. The system’s bolt-on design allows for a secure fit and reliable performance without the need for cutting or welding.
