LOWER TRAILING ARMS - 6TH GEN CAMARO, 2022-2026 CADILLAC CT-5V

The 6th Generation F-Body chassis brought numerous enhancements over the 5th gen, including a significantly stiffer frame, a wider track, an aluminum front cradle, and upgraded Alpha platform suspension geometry. Despite these improvements, the chassis still relies on sheet metal suspension links with bonded rubber bushings. While formed sheet metal links are cost-effective to produce, they are susceptible to flex and harmonic issues. Moreover, the factory bonded rubber bushings permit deflection under load and can cause binding during rotation, leading to inconsistent handling.

The A3 Speed Lower Trailing Arms address these concerns with a fully machined aluminum design and high-density, 95 durometer polyurethane bushings. High-end vehicles typically use forged aluminum suspension links because they provide an optimal balance of strength and weight where cost isn't the primary concern. A3 Speed CNC machine their arms from 7075 billet aluminum and finish them with a durable grey Hard-coat anodize.

Our bushings are injection molded to our precise specifications. With a 95 durometer rating, they offer minimal compression yet maintain enough articulation to prevent bind. These bushings enable the arm to accurately locate the spindle without negatively impacting NVH (noise, vibration, harshness) or ride quality. They feature internal grease passages for consistent lubrication, ensuring smooth, friction-free rotation and quiet operation. Additionally, they incorporate an exclusive spiral flute pattern on both the inner bore and outer thrust surface to enhance performance.

Why are spiral flutes better than straight flutes? While straight grooves parallel to the load can promote effective lubrication under certain conditions, they also act as stress risers that concentrate stress at specific points, increasing the risk of crack formation and fatigue failure. Spiral grooves mitigate these issues by promoting more uniform stress distribution and reducing sharp discontinuities, thus improving the bushing's overall reliability and lifespan.

Why are their grooves on the face of the bushing? These grooves facilitate lubrication on the bushing's thrust surface. While most aftermarket manufacturers often overlook this area due to the increased complexity and cost of manufacturing bushings with such features, it is equally crucial as the internal grooves in reducing friction and noise from the bushing.
