Rigid Collar Kits

Eliminate unwanted chassis flex and improve suspension precision with rigid collar kits from SBX Performance. These specially designed collars fit between the subframe and chassis mounting points, filling in gaps and irregularities that cause movement under load. By locking the subframe securely in place, rigid collars reduce flex, vibration, and alignment changes for a more stable driving experience.

Rigid collar kits are CNC-machined from high-strength aluminum and anodized for durability. They improve steering response, cornering stability, and overall handling feel without adding weight. Perfect for both street and track builds, rigid collars are an affordable yet effective upgrade that sharpens suspension geometry and increases driver confidence.

Pair rigid collar kits with subframe braces, sway bars, and control arms for maximum chassis rigidity and a truly dialed-in suspension setup.
