KYB Suspension Shock Absorber P/N:554359

$89.99

Description

Smooth out every mile with the KYB shock absorber Gas-a-just 554359, a high-pressure monotube gas shock that installs as a direct-fit FRONT replacement for the 2010 Dodge Ram 2500, 2010 Dodge Ram 3500, 2011-2013 RAM 2500, and 2011-2012 RAM 3500. Its components and valving are designed specifically for Dodge Rams.

Monotube gas design: Two separate working chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston — separate the gas and oil for fade-free operation and instant response, so it never experiences fade due to aeration.
More damping: Adds up to 25% more damping performance over original equipment shocks, with additional damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
Quick steering response: The higher gas pressure of the Gas-a-just responds quickly to improve steering response and helps keep Electronic Safety Systems performing as designed.
Durable rod: An ultra-smooth triple-chrome-plated piston rod reduces seal wear, since fluid leaking can be a cause of shock failure.

Signs this shock may need replacing include a bouncy ride, excessive body movement, or fluid seepage.
