Arai GP-J3 Interior

The Arai GP-J3 Interior Lining Kit is a genuine factory replacement crown and side liner assembly engineered specifically for the Arai GP-J3 open-face motorsport helmet. This is not just a basic set of cheek pads - it is a comprehensive, structural interior comfort lining that wraps completely around the upper crown, brow, and sides of the head. Over intense racing seasons, an entire helmet liner naturally degrades as it absorbs heavy perspiration, hair oils, and paddock dust. Replacing the complete assembly restores that plush, factory-fresh feel and ensures proper, safe stabilization of the helmet at speed.

Tailor Your Complete Helmet Fitment

Because every driver's head shape is unique, Arai offers this complete replacement lining in various shell-size allocations and padding depths. Whether you are replacing an old, compressed liner to restore your helmet's original hygiene, or you need to fine-tune the interior snugness for a perfect, custom fit, this integrated assembly gives you full control. Choosing a thicker depth (10mm) provides a firmer, tighter fit inside the shell, while a thinner allocation (7mm) offers additional clearance.
