QA1 79-04 Ford Mustang Lower Trailing Arms

QA1 sets the standard for premium suspension components with its comprehensive line of trailing arms, meticulously designed for optimal performance and durability. Whether you choose upper tubular, lower boxed, adjustable, or tubular trailing arms, QA1 ensures that your vehicle's suspension system operates at its peak.

All upper tubular and lower boxed trailing arms feature polyurethane bushings on both ends, delivering stability and control. For upper adjustable and lower tubular trailing arms, QA1 goes a step further, using a spherical ball or rod end assembly on the chassis end. This design eliminates bushing bind, allowing the suspension to move smoothly, keeping your tires firmly planted on the ground. The result is improved traction and a more predictable, better-handling car.

To ensure a lasting finish, all trailing arms are powder-coated in a sleek gloss black, adding a touch of durability and aesthetics. QA1's commitment to quality is evident in the construction of Boxed Trailing Arms, crafted from 0.120'' wall cold-rolled steel tubing. These arms eliminate flex and feature fluted, greasable polyurethane bushings, surpassing stock rubber bushings in performance.

For Tubular Trailing Arms, QA1 utilizes 1-1/4'' diameter, 0.120'' wall steel tubing, offering increased strength with the added advantage of lighter weight. These arms also incorporate fluted, greasable polyurethane bushings for superior performance.

The Heavy-Duty Adjustable Trailing Arms from QA1 simplify rear suspension adjustments for optimum handling and traction. With the ability to adjust the pinion angle without removing the arms, these trailing arms offer convenience and precision. They replace OE differential bushings with polyurethane for added durability and utilize a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end, promoting free movement and eliminating bushing bind.

For the ultimate in weight savings and adjustability, QA1 offers Adjustable Tubular Lower Trailing Arms in both aluminum and steel variants. These arms feature QA1's premium self-sealing and self-lubricating X Series (heat-treated chromoly steel) or A Series (aircraft aluminum) rod ends. Each kit includes (2) lower control arms with rod ends and jam nuts.

All QA1 trailing arms are sold in pairs, offering a comprehensive upgrade for your vehicle's suspension system. Choose QA1 for a combination of quality, performance, and longevity in your suspension components.
