maXpeedingrods 5000 lbs Replacement Air Helper Spring Bags with Fittings – Universal Truck Fit (G1/8 Port) – 2 Pack

Overview and fit

Designed as a universal upgrade for heavy‑duty pickups, these air helper bags support the rear suspension when carrying heavy payloads or towing. They connect via a single G1/8 inch air port and install between the axle and the frame, offering broad compatibility with many trucks and SUVs, including popular Ford, Chevrolet, GMC, and Dodge models.

Over time, the right air bag can help your vehicle respond more confidently to changing loads. While results vary, drivers may notice a steadier ride, reduced rear sag under load, and smoother transitions when moving from empty to loaded conditions.

What you get and how it performs

This 2-pack ships with air fittings and mounting hardware, enabling straightforward setup with compatible lines and valves. The design uses a durable rubber compound with thick walls to withstand frequent loading and unloading cycles, helping maintain shape and responsiveness over time.

Key benefits

• Load leveling capability up to 5,000 pounds to help prevent bottoming out and squatting
• Internal jounce bumper cushions impacts and reduces full compression on rough roads
• Multi-ply natural rubber with 4.5–5 mm thickness for robust load support
• Two bags in the kit, along with fittings, for easy installation on a wide range of trucks and SUVs

What to verify before installing

• Confirm air spring parameters: height, diameter, and bolt pattern before mounting
• Ensure compatibility with your vehicle and note the install hole size (2 × M10)
• Check that your air system can support the G1/8 port and required connections

Note: This product is designed to complement your existing suspension and should be installed following best practices and vehicle manufacturer guidelines. It is intended to offer potential performance improvements for load handling rather than guarantees for every setup.
