P2M Rear Strut Brace – Nissan S13 240SX (1989–1994) | 6063 T5 Aluminum | TIG Welded | Gunmetal / Anodized Black

Reinforce the rear shock towers of your 1989–1994 Nissan S13 240SX with the P2M rear strut brace — a direct bolt-on chassis reinforcement bar that adds structural rigidity to the rear of the S13 body shell, reducing chassis flex under cornering loads for improved handling response and more consistent suspension geometry. Constructed from 6063 T5 chambered aluminum with SPHC hot-rolled steel side brackets and P2M’s signature forged aluminum end blocks, precision TIG hand-welded throughout.

Key Features

• Reduces Rear Chassis Flex – Improved Handling Consistency: The S13’s unibody chassis flexes under lateral cornering loads — particularly at the rear shock towers, where the strut mounting points are subject to the highest stress during hard cornering. Chassis flex at the shock towers allows the suspension geometry to shift dynamically under load, reducing handling predictability and consistency. The P2M rear strut brace ties the two rear shock towers together, resisting this flex and maintaining more consistent rear suspension geometry under cornering loads
• 6063 T5 Chambered Aluminum Body – 4.5mm Wall Thickness: Center bar constructed from 6063 T5 aluminum in a chambered (hollow section) profile — providing the strength required to resist chassis flex while keeping weight to a minimum. 4.5mm wall thickness provides the rigidity needed for effective chassis reinforcement without unnecessary mass
• SPHC Hot-Rolled Steel Side Brackets – Powder Coated Gunmetal Gray: Side brackets are constructed from SPHC hot-rolled steel — a strong, weldable structural steel used in automotive chassis applications. Powder coated in gunmetal gray for corrosion resistance and a clean, purposeful appearance that complements the anodized black center bar
• P2M Forged Aluminum End Blocks: P2M’s signature forged aluminum end blocks at each strut tower mounting point — forged construction provides superior strength and fatigue resistance compared to cast or machined billet end blocks at the highest-stress points of the brace
• Precision TIG Hand-Welded Construction: All welds are precision TIG hand-welded — TIG welding provides cleaner, stronger, and more precise welds than MIG welding for structural chassis components, ensuring long-term integrity at all weld joints
• Direct Bolt-On – 1989–1994 Nissan S13 240SX: Direct bolt-on fitment for the 1989–1994 Nissan S13 240SX — uses factory shock tower mounting points with no drilling, cutting, or modifications required. Verify your specific model year before ordering
