Direct-Axle Air Bag Mounts for 3" Axles - Slotted (Weld-on)

Direct-Axle Air Bag Mounts for 3" Axles - Slotted (Weld-On) - #180-5400

The Direct-Axle Slotted Air Bag Mounts are engineered for builds that require maximum surface area and uncompromising strength. Featuring our largest mounting face at 7" x 5", these brackets provide an oversized foundation that is ideal for larger air springs or setups requiring significant lateral adjustment. This "zero-offset" design sits directly over the axle, ensuring 1:1 lift efficiency in a low-profile package.

The GSI Advantage

• Heavy-Duty 1/4" Steel: Overbuilt for the long haul. Laser-cut from 1/4" A36 high-strength steel, these mounts are designed to handle the massive forces of heavy-duty air suspension without the flexing or bowing common in smaller, thinner mounts.

• Massive 7" x 5" Mounting Face: The oversized top plate provides a superior foundation. Whether you are running standard bags or larger diameter air springs, this footprint ensures the bag base is fully supported to prevent bellows distortion.

• Style 2 Slotted Adjustability: Features three precision-cut oval slots. The 7-inch length allows for significant "slide" adjustment, giving you the freedom to perfectly align your bags with your upper frame mounts regardless of minor axle shifts.

• Low-Profile 2.5" Height: With an overall height of only 2.5", these mounts are the perfect solution for "laid-out" trucks where every fraction of an inch matters for bed floor and notch clearance.

• Direct-Vertical Loading: Designed specifically for 3" diameter axle tubes, these brackets transfer 100% of the air spring's force directly to the axle, eliminating the leverage stress associated with offset mounting.
