Balance in ride, handling

With its choice of two powerful engines and strong body-on-frame construction, Rainier carries solid truck credentials. But its silky feel and performance on the road are more akin to a fine touring car, the result of Rainier being tuned to achieve an excellent balance in ride, handling and acoustics.

Rainier's surprisingly smooth ride is derived from its world-class independent front suspension, and five-link, electronically controlled rear air suspension designed to stand up to the most demanding conditions. With this system, air springs replace the standard rear coil springs for superior damping and improved isolation from road noise. Sensors manage a compressor that instantly adjusts air spring pressure to maintain a level load.

Rainier's power-assisted, rack-and-pinion steering is precise and responsive while the four-wheel vented disc brakes provide outstanding performance and world-class levels of brake feel, wear resistance and noise reduction.

A four-wheel anti-lock brake system (ABS) and locking rear differential are standard on Rainier. Two-wheel-drive models are also standard-equipped with traction assist, improving Rainier's ability to handle slippery road surfaces. A standard equipment list that includes Bilstein shocks, 17-inch wheels and premium Michelin tires also contributes to Rainier's superior stability and road-command characteristics.
