The AB Tools V675 Indespension replacement damper is an essential maintenance component for owners of trailers equipped with heavy-duty braked hitches. Designed for units with a capacity between 2000kg and 3500kg, this damper provides the necessary resistance to ensure smooth towing and braking performance by managing the overrun action of the hitch. While it offers a precise, direct-fit replacement for the V675 model, users should verify their specific hitch model number before installation to ensure compatibility with their existing coupling system.

No, the V675 is specifically designed for hitches with a 2000kg to 3500kg capacity. Using it on an undersized trailer may lead to poor braking performance.
You will typically need a standard socket set and wrenches to remove the coupling bolts, along with a torque wrench to ensure the bolts are re-tightened to manufacturer specifications.
Common symptoms include the trailer braking too sharply, a rattling or clunking sound during stopping, or the hitch sliding back into the tube without any resistance.
This listing is for the damper unit itself. You should reuse your existing bolts, provided they are not damaged, or replace them with new high-tensile hardware of the same specification.
If you are comfortable with basic mechanical repairs, you can install it; however, because this is a safety-critical braking component, professional installation is recommended if you are unsure.
This often indicates a failed damper. Check the damper for fluid leaks and ensure it is still providing resistance; replace if necessary.
Ensure the housing is free of debris and properly greased. If the internal seals have failed, the unit will require replacement.
Verify the V675 model number matches your hitch. Ensure no obstructions or old bolt fragments remain inside the tube.
Before starting the installation, ensure the trailer is on level ground and the handbrake is fully engaged. It is recommended to support the weight of the hitch assembly safely.
