JOES Racing Products A-Arm Slug

JOES Racing Products A-Arm Slugs, also called control arm slugs or caster slugs, let you fine-tune your upper control arm geometry for circle track and racing use. They are designed for use with JOES slotted A-arms. Swapping slugs changes the offset in small steps, so you can adjust caster and keep your chassis setup repeatable.

Key Features:

• Machined aluminum construction keeps weight low while holding up to racing use
• Black anodized finish for a clean look and surface protection
• Laser-engraved markings make each slug easy to identify in the pits
• Made in the USA by JOES Racing Products
• Slotted A-arm compatible for quick geometry adjustments

JOES Racing Products is run by racers who know what competitive parts need to do. These A-arm slugs give you a simple, precise way to tune your front suspension for the track.
