Subframe Mounting Bolt Kit Holden 48-215 FX FJ - SBK3A

When working on your classic, it doesn’t take much movement in the front subframe to cause clunks, misalignment or vague steering feel. The Subframe Mounting Bolt Kit is designed specifically for Holden 28-215 FX and FJ models, providing the correct high‑tensile hardware needed to securely fasten the front K-Frame to the chassis outriggers.
