What is pinion angle and why does it need correction on a lifted Jeep?

Pinion angle refers to the angle of your driveshaft relative to your differential. When you lift a Jeep, the driveshaft angle changes, which can cause vibrations and premature wear on your U-joints and differential. These adjustable trailing arms allow you to correct that angle for a smoother ride and longer drivetrain life.

Do these trailing arms come with all the necessary hardware for installation?

This kit is supplied as a complete set of upper trailing arms, fully assembled with SuperPro bushings. For a complete installation, it's recommended to refer to the manufacturer's instructions to ensure all necessary hardware and mounting procedures are followed.

Can these be used with other suspension components?

Yes, these upper trailing arms can be used as a standalone upgrade. They are also designed to work well with SuperPro's HD adjustable rear lower control arms and HD adjustable front arms for a more comprehensive suspension system.

Product Details

If you've lifted your Jeep Wrangler JK or JL and are looking to fine-tune its suspension, this set of upper trailing arms from Superpro is a solid option. These arms are specifically designed to correct the pinion angle on lifted vehicles, which is crucial for drivetrain longevity and smooth operation. They're built to handle everything from daily driving to more demanding off-road excursions, offering an improved feel both on and off the pavement.

What sets these apart is their off-car adjustability, allowing you to precisely dial in your pinion angle correction for lifts up to 4 inches. They come fully assembled with Superpro's own durable bushings, which are optimized for longevity and performance without introducing unwanted noise, vibration, or harshness (NVH). This attention to detail means you get a more comfortable ride and a suspension component that's built to last. The Superpro R&D team in Australia has thoroughly tested and developed these arms, ensuring they meet high standards for durability and effectiveness.

You can install these as a standalone upgrade to address pinion angle issues, or pair them with Superpro's HD adjustable lower rear and front control arms for a comprehensive suspension overhaul. This kit is a well-built solution for Wrangler owners looking to get the most out of their lifted setup.
