OX Series Heavy-Duty (HD) Bracket

Introduced in early 2025, the OX Series Heavy-Duty Bracket was built with one goal: to be the strongest door mounting brackets for Sprinters and support the most versatile rear door carrier out there.

The OX Rear Door Carrier is built to handle over 300 lbs, but in the real world, the weak point was never the carrier — it was the factory door mounting area. The HD Bracket solves that problem by reinforcing the mounting zone using both the inner and outer layers of the rear door — a first in the industry — drastically reducing flex and increasing stability where it matters most. This kit includes both top and bottom mounting brackets and is specific to either the passenger or driver side.

With the HD Bracket installed, you can confidently run heavier loads like:

• Full-size spare tires
• Bike racks ( E-Bikes included)
• Storage Boxes
• Expedition gear and recovery equipment

This upgrade is all about strength, rigidity, and long-term durability, especially for customers who regularly push their builds beyond typical loads.

Included with every Sprinter OX Rear Door Carrier since April 2025
If you purchased your carrier before April 2025, we highly recommend upgrading to the HD Bracket for maximum performance and peace of mind.
