The PRT rear shock absorbers (part numbers 334394 and 334395) are designed as direct-fit replacements for the Lexus RX330, RX350, RX400h (2004–2009), and compatible Toyota Highlander models from the same era. These twin-tube shocks restore factory-like ride comfort and handling by effectively controlling body movement and ensuring consistent contact between the tires and road surface. Built to OEM specifications, they come with correct mounting points and valving to match the vehicle’s original suspension dynamics.

Their robust construction includes precision-welded steel bodies and durable seals to help resist leaks, while the twin-tube design maintains stable damping performance across a range of driving conditions—from daily commuting to occasional highway trips. Users often report improved ride stability, reduced body roll, and better overall comfort after installation. As a cost-effective alternative to dealer parts, PRT rear shocks (334394 left / 334395 right) help keep your RX330’s suspension responsive, balanced, and comfortable for everyday driving.
