LOSTAR Weld-On Rear Air Bag Mounting Brackets 4pc Kit — Universal 2500/2600 Series Fit, Heavy-Gauge Steel

LOSTAR 4-piece weld-on rear air bag mounting bracket kit provides a universal, heavy-duty solution to attach upper and lower air springs to most pickup trucks and custom rear axles.

These bolt-free mounting plates are built from thick steel and shaped for rear upper and lower axle positions, offering a straightforward way to add air ride capability to trucks, hot rods, rat rods, and many classic cars. The set includes two upper and two lower brackets sized for common axle diameters and compatible with 2500 and 2600 series air bags. Finished with a durable, corrosion-resistant coating and precise bends for secure weld joints, the brackets arrive ready to be welded into place as part of a custom or replacement rear suspension setup.

Will these brackets fit my vehicle's axle and air bag model?

Yes — the design accommodates a wide range of rear axle diameters and common air bag sizes used in aftermarket systems. They are intended to mount on axles between approximately 2.75 inches and 3.25 inches and accept 2500 and 2600 series air springs, making them compatible with many trucks and custom builds.

• Fits axle diameters: ~2.75"–3.25"
• Compatible with 2500 and 2600 series air bags
• Includes both left and right upper and lower brackets
• Universal profile suits pickups, hot rods, and classic cars

How strong and durable are these weld-on mounting plates?

Fabricated from heavy-gauge steel, the brackets are engineered for high load capacity and long service life under regular driving and show use. The precision cuts and factory bends give reliable welding surfaces, while the protective finish resists chips, rust, and road debris to preserve structural integrity.

• Thick full-steel construction for load-bearing strength
• Precision-cut edges and consistent bends for strong welds
• Scratch- and corrosion-resistant coating for longevity
• Designed to withstand road exposure and rough conditions

What comes in the kit and what else will I need to finish the installation?

The kit supplies four welded-mount plates — two rear upper and two rear lower — so you have the complete set for the rear axle on either side of the vehicle. Air springs, airlines, fittings, brackets for upper body attachment, and welding supplies are not included, so plan for those items depending on your suspension layout and installer preferences.

• Included: 2 rear upper axle brackets and 2 rear lower axle brackets
• Not included: air springs, air lines, fittings, and fasteners
• Recommended: competent welder or professional fab shop for installation
• Works with common air suspension components in custom builds

How do these brackets perform for show cars versus daily drivers?

The brackets are finished and robust enough for both show-quality restorations and everyday vehicles. The protective coating and solid steel make them suitable for cars exposed to salt and moisture, yet their clean, functional shape also fits custom and restored vehicles where appearance and reliability both matter.

• Coating resists corrosion for winter or coastal use
• Rugged construction handles heavier loads and repeated use
• Sleek, practical geometry blends into custom builds
• Ideal for both display vehicles and daily-driven trucks

Who is this for: This LOSTAR kit is aimed at DIY fabricators, hot rod builders, small shops, and truck owners converting to or upgrading rear air suspension. If you need a weld-on solution sized for common rear axles and 2500/2600 series air bags, want heavy-gauge steel with a corrosion-resistant finish, and plan to have the brackets welded in place, this 4-piece set supplies the core mounting hardware for a durable rear air ride setup.
