Product Description

The Firestone 8781 is a Red Label extreme duty replacement air spring, engineered as the service bag for Firestone's Red Label extreme duty air spring kit W21-760-2700. Rated for a 2,800 lb load capacity and operating up to 150 PSI with a 400 PSI test pressure, this air spring delivers meaningfully higher pressure capability than Firestone's standard Ride-Rite air springs, which top out around 100 PSI.

Environmentally friendly, coated metal end plates provide superior corrosion resistance, while a machined, welded 1/4-inch NPT air intake hole and a time-proven, rolled crimp seal keep the rubber air bag securely fastened to the end plates for reliable, long-term performance. Every Firestone air spring is engineered and tested in ISO-certified facilities to meet strict quality and customer specifications.

This replacement air spring is intended for owners of an existing Red Label extreme duty kit whose original air bag needs replacement due to wear or damage, and is not intended to supplement standard air springs in a standard Ride-Rite kit. Backed by Firestone's warranty against defects in workmanship or material for a period of 2 years, excluding damage from accidents, corrosion, improper installation, incorrect applications, overloading, or custom applications not specified under OEM cross references.
