About AST: Precision Suspension Components

AST has built a solid reputation among automotive enthusiasts and professional mechanics alike as a dependable manufacturer of precision-engineered suspension components. With a catalog spanning a wide range of vehicle applications, AST focuses on delivering parts that restore and maintain the handling characteristics your vehicle was designed to achieve — making them a trusted name for anyone serious about suspension integrity.

Engineered for the Demands of Real-World Driving

Suspension bushings are among the hardest-working components on any vehicle. They absorb road vibration, reduce noise, and keep suspension geometry properly aligned through every corner, bump, and braking event. When these components wear out, drivers often notice increased body roll, imprecise steering, clunking noises, and uneven tire wear. AST addresses these challenges head-on with bushing solutions engineered to meet or exceed OEM specifications across a broad range of makes and models.

At the heart of the AST lineup are suspension control arm bushings — one of the brand's most expansive categories, covering dozens of applications. Control arm bushings are critical for maintaining proper wheel alignment and absorbing the constant forces transmitted through the suspension, and AST's offerings are built to provide long-lasting, stable performance in demanding conditions.

For trucks, SUVs, and performance vehicles that use a trailing arm suspension layout, AST's suspension trailing arm bushings offer a direct-fit replacement solution designed to restore proper axle location and handling predictability. Proper trailing arm bushing condition is essential for maintaining rear suspension geometry, especially under load or during spirited driving.

AST also produces radius arm bushings, which are commonly found on solid front axle vehicles like older trucks and off-road platforms. These bushings play an important role in controlling axle movement and preventing shimmy or wander — issues that become pronounced when radius arm bushings deteriorate.

Handling and body roll control depend heavily on properly functioning sway bar components, and AST's suspension stabilizer bar bushings are designed to keep the sway bar securely located and functioning as intended. With a broad range of fitments, these bushings are a go-to solution for restoring taut, responsive handling.

Rounding out the lineup, AST offers suspension subframe bushings that isolate the subframe from the body structure, reducing noise, vibration, and harshness (NVH) while maintaining precise suspension geometry. Worn subframe bushings can cause a noticeable deterioration in ride quality and handling, making timely replacement an important part of any comprehensive suspension refresh.
