Polyair Red Series Kit to suit Holden HQ - HZ (incl. WB Statesman & Monaro) 1971-1984 - standard height

Polyair Red Series - Load Assist Airbag Kit (for Coil Spring Vehicles)

The Polyair Red Series airbag kits are purpose-built for coil-spring vehicles, offering reliable load support and improved handling when carrying extra weight or towing. Whether you’re loading up the rear of your vehicle or hitching up a trailer or caravan, sagging suspension can lead to compromised safety and ride quality.

Common symptoms of rear-end sag include:

• Suspension bottoming out

• A harsh or bumpy ride

• Excessive sway and body roll

• Unpredictable braking behaviour

• Poor headlight alignment

Installing a Polyair Red Series kit helps to reduce or eliminate these issues by providing adjustable support where and when it’s needed. With air pressure settings from 5-35psi, the system allows you to fine-tune your suspension for different load types and driving conditions.

While upgrading your vehicle’s coil springs for constant heavy loads is ideal, many factory springs are rated beyond what you typically carry day-to-day - leading to a rough, uncomfortable ride when unloaded. The Red Series bridges that gap, giving you smooth, OE-like comfort for everyday driving, with the flexibility to adjust support when you’re towing or carrying extra weight. Simple, effective, and versatile.

Key Features:

• Air adjustable from 5-35psi

• Durable, moulded polyurethane construction

• Straightforward installation with basic tools

• Easy-to-follow, illustrated instructions included

• Quick-connect, user-friendly air fittings

• Backed by a 2-year, unlimited kilometre warranty

Whether it’s the work week or the weekend, the Polyair Red Series gives your suspension the adaptability it needs—without compromising ride comfort.

Shipping

We offer FREE shipping to all metro areas (excluding WA, TAS and NT).

If you live on the Australian coast, that does not mean you are subject to free shipping.

Express shipping times and free shipping times are only to be counted once the order has been shipped from our warehouses. Our free shipping and express shipping services both have the same order processing times. We first have to raise the order, then we send it to one of our warehouses for processing and once ready it will be shipped from the warehouse. The difference between express and free shipping services, is the time it takes for the item to be transported from our warehouse to your address.

Our free shipping policy is determined by densely populated metro locations and the viability of distance travelled from our distribution centres. We are constantly expanding our warehousing, so areas covered by free shipping are subject to change. See our shipping policy here.
