Construction & Design

The SuperPro Upper Trailing Arms are constructed using durable materials designed to withstand the stresses of off-road and daily driving. The bushings are made from proprietary polyurethane compounds that resist cracking, tearing, and deformation, providing a longer service life compared to OEM rubber bushings. The arms themselves feature precision-machined mounting points and are finished with corrosion-resistant coatings to prevent rust and corrosion.

The design emphasizes strength, durability, and precise fitment, ensuring that your Jeep's suspension geometry remains optimal. This not only improves handling but also contributes to a smoother, more controlled ride over uneven terrain and challenging conditions.

Installation & Fitment

The SuperPro Upper Trailing Arm Set is designed for a straightforward bolt-on installation. It mounts directly to the factory suspension points without the need for cutting, drilling, or additional modifications. Basic mechanical skills and standard hand tools are sufficient for installation, and no specialized tuning is required. For best results, alignment adjustments should be performed after installation to ensure optimal handling and tire wear.
