The PER4MAX Thunder Titanium is an elite, championship-level sports wheelchair engineered specifically for high-impact court play and top-tier athletic competition. Hand-built in the USA by PER4MAX, Inc., the Thunder Titanium represents the flagship tier of the Thunder series, upgrading the standard 6000/7000 aircraft aluminum frame to Grade 9 seamless aerospace titanium.

Designed for sports such as wheelchair basketball, tennis, softball, rugby, and lacrosse, this chair delivers maximum power transfer, high acceleration, and incredible frame durability.

Key Features & Material Advantages

Grade 9 Titanium Frame: Titanium offers the highest strength-to-weight ratio of any frame material. It is significantly stronger and more fatigue-resistant than 6000 or 7000 series aluminum, while providing natural shock and vibration absorption to cushion hard impacts on the court.

Custom Rigid Construction: Each Thunder Titanium is built to the athlete's exact anatomical measurements and posture. The rigid frame eliminates unnecessary bolts and hardware, preventing frame flex and ensuring every ounce of pushing power goes directly into movement.

Strategic Adjustability: While the main body is rigid for structural integrity, key performance points remain adjustable—including the Center of Gravity (CG), backrest angle, and lower leg length positioning.

Anti-Tip System: Comes standard with a rigid 5th wheel (with optional dual 5th wheel or 6th wheel configurations) to prevent tipping during aggressive backward acceleration and rebounding.

Precision P4X Machined Parts: Built using custom CNC-machined aluminum clamps, housing pots, and axle receivers designed to withstand heavy court collisions.
