Weapon R Polished Billet Aluminum Power Steering Reservoir Tank - 2003-2006 Nissan 350Z
The Weapon R 826-121-101 Power Steering Reservoir Tank is a direct-replacement upgrade for the factory plastic reservoir on 2003-2006 Nissan 350Z models (all trims). CNC machined from billet aluminum and polished to a brilliant show-quality finish, this tank eliminates the ugly, heat-soaking OEM plastic unit while providing superior heat dissipation and a sleek under-hood appearance. The baffled design prevents fluid aeration during aggressive cornering and track use, maintaining consistent power steering performance. A perfect complement to any 350Z build whether street, show, or track day ready.
