Function & Features

• Rear shock absorbers—or struts—serve to dampen suspension movement, absorbing impacts from the road and ensuring ride comfort, vehicle stability, and control during acceleration, braking, and cornering.
• OEM and high-quality aftermarket units use gas-filled designs to maintain consistent damping performance and resist fade during prolonged use (e.g., highway speeds or heavy loads).

• Check warranty & support: Some aftermarket products offer coverage ranging from 12 months (SEJ, Kingsteel) up to 10 years (Torchbeam), indicating confidence in durability   .
