SuperPro Lower Trailing Arm Set: Jeep Wrangler JK 2007-2017 / 2018

SuperPro Lower Trailing Arm Set

2007–2018 Jeep Wrangler JK & JL

TRC1187

Overview:

The SuperPro Lower Trailing Arm Set is engineered specifically for Jeep Wrangler JK and JL models from 2007 through 2018, designed to enhance suspension geometry on lifted vehicles. This kit addresses pinion angle correction, a critical factor for maintaining drivetrain reliability and smooth power delivery after suspension lifts up to 4 inches. Ideal for off-road enthusiasts and daily drivers alike, these adjustable trailing arms improve both on-road handling and off-road articulation, ensuring your Jeep performs optimally under varied conditions.

Supplied as a complete, fully assembled kit with premium SuperPro bushings, this trailing arm set offers a durable and maintenance-friendly upgrade. It can be installed as a standalone solution or combined with SuperPro’s HD adjustable rear upper control arms and HD adjustable front arms for a comprehensive suspension enhancement.

Key Features:

Designed with precision and durability in mind, the SuperPro Lower Trailing Arm Set delivers multiple benefits for lifted Jeep Wrangler owners:

• Off-car adjustable trailing arms for precise pinion angle correction
• Compatible with suspension lifts up to 4 inches
• Supplied fully assembled with high-quality SuperPro polyurethane bushings
• Improves drivetrain alignment to reduce vibrations and premature wear
• Enhances on-road stability and off-road articulation
• Can be used independently or with SuperPro HD adjustable upper and front control arms
• Tested and developed by SuperPro’s Australian R&D team for reliability and performance
• Optimized to minimize noise, vibration, and harshness (NVH)
• Durable construction designed for long-lasting performance in demanding conditions

Construction & Design:

The trailing arms are constructed from robust, high-grade steel to withstand the rigors of off-road use and lifted suspension loads. Each arm is precision-engineered to provide a perfect fit and alignment, ensuring consistent performance and durability. The inclusion of SuperPro’s proprietary polyurethane bushings enhances longevity and reduces unwanted NVH, delivering a quieter and more controlled ride compared to traditional rubber bushings.

Adjustability is a key design feature, allowing for off-vehicle fine-tuning of the pinion angle. This flexibility helps maintain optimal driveline angles, reducing stress on universal joints and preventing vibrations that can lead to component failure.

Installation & Fitment:

The SuperPro Lower Trailing Arm Set is designed for straightforward installation on Jeep Wrangler JK and JL models from 2007 to 2018. The kit fits lifted vehicles with up to 4 inches of suspension lift and requires no major modifications to the chassis or suspension components. Off-car adjustability allows for precise pinion angle tuning before installation, simplifying the setup process and ensuring optimal driveline alignment.

For best results, it is recommended to install this kit alongside SuperPro’s HD adjustable rear upper control arms and HD adjustable front arms to achieve a fully balanced and adjustable suspension system.
