HGV wiper blades and arms for commercial vehicles
Wiper blade condition affects driver visibility and is a DVSA annual test item. A wiper blade that smears, chatters, or fails to clear the screen is a defect that will result in a test failure or a roadside prohibition. Wiper blades on commercial vehicles are typically longer than passenger car blades, and blade length varies between makes and cab generations.
Most modern HGV cabs use flat-blade wiper systems (also called beam blades), which maintain even pressure across the full blade length and perform better at motorway speeds than traditional bracket-type blades. Older cab designs use traditional bracket wipers with a steel frame. Fitting the wrong blade type for the wiper arm attachment can result in incorrect fitment or an incompatible attachment point.
Wiper arm condition should be checked whenever the blade is changed: a worn wiper arm spring that no longer holds the blade against the glass causes the same smearing and chattering symptoms as a worn blade, and fitting a new blade to a worn arm wastes the blade. If the new blade doesn't improve clearing performance, the arm is the likely remaining cause. Call us on 01527 598 000 or order online for next-day delivery.
Frequently Asked Questions
What wiper blade size do I need for my HGV?
Wiper blade length varies by truck make, model, and cab generation. Common HGV wiper lengths range from 600mm to 800mm depending on the application. Check your vehicle's documentation or the current blade for the correct length. Fitting a blade that is too short leaves uncovered glass area; too long and the blade may contact the cab structure.
What is the difference between flat-blade and bracket wiper blades?
Flat-blade (beam) wipers have no external metal frame: the blade is a single curved rubber element with internal tensioning that maintains even contact pressure across its length. Traditional bracket wipers have a metal superstructure with multiple contact points that press the rubber against the glass. Modern HGV cabs predominantly use flat-blade systems. Check the attachment type on your wiper arm before ordering, as the two types use different mounting connections.
How often should I replace wiper blades on an HGV?
Replace wiper blades annually as a minimum, or whenever they begin to smear, chatter, or skip across the screen. In practice, vehicles covering high mileage or operating in harsh conditions may need replacement more frequently. Checking blade condition before the DVSA annual test is good practice: a failed wiper inspection is one of the more avoidable test failures.
Do you stock wiper arms for HGVs?
Yes. We stock wiper arms for the main HGV makes where available. If a new blade doesn't resolve a smearing problem, check the arm spring tension. A weak arm spring that no longer holds the blade against the screen at speed is the second most common cause of poor wiper performance after a worn blade. Replace the arm if the spring is weak or the pivot is worn.
