DAF 1377827 1818918 Shock Absorber
DAF 1377827 1818918 Shock Absorber: Technical Overview, Functionality, and Operational Importance
The DAF 1377827 / 1818918 Shock Absorber is a key suspension component designed for use in DAF heavy-duty commercial vehicles. It plays a critical role in managing road vibrations, stabilizing vehicle movement, and ensuring driver comfort. Often fitted in the front or rear axle suspension of DAF trucks such as the XF, CF, and LF series, this shock absorber is engineered to meet the demanding requirements of long-haul freight, distribution, and construction transport operations.
1. Function of a Shock Absorber in Heavy Vehicles
Shock absorbers are hydraulic devices that dampen and control the rebound and compression of a vehicle’s suspension system. In heavy-duty trucks, this function is especially important due to:
High vehicle weight and load variations
Frequent exposure to rough road conditions
Long hours of continuous operation
The DAF 1377827 1818918 Shock Absorber reduces chassis oscillation by converting kinetic energy from suspension movement into heat energy, which is then dissipated through hydraulic fluid. This improves vehicle stability and control during braking, acceleration, and cornering.

Recommended DAF 1377827 1818918 Shock Absorber Inspection Interval: Every 60,000–90,000 km or during routine suspension service
Replacement Signs:
Uneven tire wear
Excessive bouncing or swaying during turns
Oil leakage from the shock body
Noisy suspension (clunking or rattling sounds)
Increased braking distance or poor vehicle control
Replacement Procedure:
Lift the vehicle and support securely
Remove the bolts securing the top and bottom mounts
Detach the old shock absorber
Install the new 1377827 / 1818918 shock, torquing bolts to DAF specs
Test drive to verify ride quality and damping performance
