Air Spring Rolling Lobe 410.P8708 KGA Auto Parts Air Bag Replacement

Description

Product Overview

The KGA Air Spring Rolling Lobe 410.P8708 is engineered as a high‑performance replacement air bag for commercial trucks, trailers, and heavy‑duty vehicles that rely on the Firestone 8708 series. Constructed from a reinforced rubber composite, the bag features a seamless inner chamber that resists punctures, UV degradation, and temperature extremes. The rolling lobe design distributes load evenly across the spring, reducing stress on mounting points and extending service life.

Precision machining yields exact dimensions of 13.7 × 13.7 × 20.5 inches, ensuring a direct fit in OEM housings without the need for modifications. The part carries multiple OEM numbers—including Contitech 1110.5A‑16P523, Goodyear 1R14093, and Hendrickson C20901—so it serves a broad range of applications across the transportation industry. Each unit undergoes a 100 % visual inspection, pressure testing to 150 psi, and a three‑year limited warranty for peace of mind.

Manufacturing takes place in a climate‑controlled facility where state‑of‑the‑art extrusion and vulcanization technology guarantee uniform wall thickness and consistent elasticity. Quality‑assurance protocols include dimensional verification, leak testing, and endurance cycling that simulates real‑world operating conditions. This rigorous process results in an air spring that not only matches but often exceeds the performance of original equipment manufacturers.

The rolling lobe air spring also offers superior heat dissipation, allowing it to maintain optimal pressure during prolonged heavy‑load operations. Its robust construction minimizes the risk of premature failure, providing fleet managers with lower total‑ownership costs and reduced downtime. By choosing this KGA product, customers gain a reliable component that supports vehicle stability, ride comfort, and cargo safety.

Usage

Designed for suspension systems that demand consistent air pressure, this rolling lobe spring excels in both on‑road and off‑road environments. Fleet operators will appreciate its ability to maintain ride height under varying payloads, while independent mechanics value the straightforward installation process that matches the original factory procedure.

The air bag performs reliably in extreme climates—from sub‑zero winter routes to hot desert highways—thanks to its temperature‑stable polymer blend. It is ideal for long‑haul trucks, refrigerated trailers, dump bodies, and any equipment that uses a rolling‑lobe air spring to absorb shocks and support heavy loads.

Installation is simplified by the plug‑and‑play design: depressurize the existing spring, remove mounting bolts, slide the old bag out of the housing, insert the new KGA air bag, re‑attach bolts, and reconnect the air line. Detailed step‑by‑step instructions are included in the packaging, and our technical support team can walk you through any questions.

Regular maintenance involves checking for air leaks, inspecting the rubber for signs of wear, and verifying that the pressure regulator remains within manufacturer specifications. Following these simple checks helps extend the service interval and ensures the spring continues to deliver optimal performance throughout its lifespan.
