Why Choose This Modulator Valve Assembly
The modulator valve assembly is a critical safety component in your trailer ABS system — it rapidly modulates brake pressure at each wheel to prevent lockup during hard braking, maintaining trailer stability and directional control under heavy load. A failing modulator valve leads to ABS fault codes, loss of anti-lock braking function, increased stopping distances, and compromised trailer safety. This replacement unit delivers:
- Consistent brake pressure modulation – Engineered to maintain correct valve cycling speed and hydraulic response for your trailer TCS 2/ECU ABS control unit
- Exact-fit installation – Direct replacement with correct port configuration, solenoid interface, and mounting compatibility
- Durable construction – Built to withstand continuous heavy-duty braking cycles, road vibration, and the demanding conditions of commercial trailer operation
- Cost-effective solution – Aftermarket quality at a fraction of dealer pricing

Frequently Asked Questions
What will shipping cost?
Shipping is calculated in your cart. Enter your province and postal code to see the available rate before checkout.
When will my order arrive?
Processing normally takes 1–2 business days. Estimated delivery to Canada is 4–7 workdays after dispatch. For parts weighing over 68 kg, delivery may take 5–10 workdays. Carrier or customs delays may add time.
Will I pay Canadian duties or GST?
Yes. Prices do not include Canadian import duties, GST/HST, or customs-clearance fees. If charges apply, the carrier or Canadian customs will contact you for payment before delivery.
Customs duty: Auto parts imported from China commonly have duty rates of approximately 6%–8.5% of the CIF value (cost, insurance, and freight), depending on the product’s HS code. Canada and China do not have a free trade agreement.
GST/HST: A 5% federal GST generally applies to commercial imports. Depending on the destination province, a combined HST rate of approximately 13%–15% may apply instead.
These rates are estimates. The final amount is determined by Canadian customs based on the product classification, declared value, origin, and destination.
