• Thread/Length: M14 × 1.5 × 75 mm
• Application: Rear control arm to coffin arm mounting point

Suspension bolts in this location are subject to high load cycles, tolerance wear, and exposure to elements. If the original bolt is stretched, corroded, or re-used beyond service life, it can compromise alignment, introduce movement in the suspension joints, and lead to poor handling or uneven tyre wear. Replacing with the correct bolt restores the secure clamping required for optimal rear suspension performance.
