Construction & Design:

The Rancho Adjustable Control Arm Kit is crafted from heavy-duty 2-inch outer diameter DOM (Drawn Over Mandrel) steel tubing with a 0.188-inch wall thickness, ensuring exceptional strength and resistance to bending or flexing under demanding off-road conditions. The forged ends provide reinforced mounting points for enhanced durability and longevity.

Rancho’s proprietary D2 bushings incorporate a PTFE liner that acts as a built-in lubricant, eliminating the need for regular greasing and minimizing wear. This design reduces noise and vibration while maintaining articulation for improved suspension performance. The entire assembly is finished with a robust black powder-coat that resists corrosion, protecting the control arms from environmental damage and extending their service life.
