SPC Performance Adjustable Upper Control Arms for Nissan Frontier, Pathfinder, and Xterra – Part #35540

Description

Designed, engineered, and assembled in Colorado, the SPC Performance part #35540 adjustable upper control arms offer a significant upgrade for Nissan Frontier, Pathfinder, and Xterra owners seeking improved handling and alignment. Constructed from forged steel, these control arms provide superior strength and durability, ensuring reliable performance even in demanding environments. The inclusion of maintenance-free ball joints and sealed xAxis™ flex joints in bonded rubber sleeves allows for correction of alignment angles and helps restore factory ride quality. These features work together to improve suspension travel, tire wear, and the tire’s positioning within the wheel well, especially when fitting larger tires without the need for frame or fender modifications. The control arms are designed with increased clearance to navigate around the spring bucket and offer a full 80° of ball joint articulation for maximum flexibility. Built-in positive caster adjustment for lifted vehicles helps maintain proper handling and steering response, reducing issues such as wandering that can occur after lifting. The patented ball joint with a larger stud cross section enhances strength and longevity, and the E-Nickel coating provides excellent corrosion resistance. The fully sealed ball joint architecture ensures a maintenance-free experience by keeping grease in and contaminants out. The adjustable range includes camber correction of ±2.00° and caster adjustment from 0.00° to +4.00°, enabling precise alignment settings. Sold in pairs, these control arms are essential for off-road enthusiasts and truck owners who want to maximize their vehicle’s performance, handling, and tire clearance while maintaining factory-like ride quality. Whether upgrading for larger tires or restoring proper alignment after a lift, SPC’s control arms are engineered to deliver durability, adjustability, and enhanced drivability for your Nissan truck.
