Coil Assist Air Suspension to suit Toyota Prado 120 and 150 Series by Boss Air Suspension

Boss Extreme Series Airbags – Toyota Prado Coil Assist

Give your Toyota Prado the extra muscle it needs with our Boss Extreme Series Coil Assist. Sitting right beside your coil springs, these airbags are ready to tackle heavy loads and tough tracks, ensuring a smooth and controlled ride, no matter the adventure.

This kit is designed for the following Prado Series:

- Prado 120 Series | 2003~2009 - Prado 150 Series | 2009~2023

What Makes Them Great?

  • Built to Handle It: Rated at 2500lb (1136kg) per side, our airbags are tough enough for anything you throw at them.
  • Tested to the Extreme: Government-approved and tested up to 750psi, so you know you're getting quality that lasts.
  • Made by Boss Air Suspension: All Boss airbags are proudly manufactured by us and carry our branding. Beware of unbranded copies from other companies, often from overseas.
  • Perfect Fit for All Sorts: Whether it’s a 4WD, ute, trailer, motorhome, or even agricultural machinery, Boss airbags have you covered.
  • Dial in the Perfect Ride
    • Most dual cab utes run around 15-45psi, depending on the load. To get the best from your kit, inflate your airbags just enough to level out your ride. This keeps the load evenly spread across your suspension, preventing any single part from taking on too much strain.
    • With over 13,000 kits sold across Australia, from 4WD enthusiasts to tradies and tour operators, Boss airbags are a proven choice for anyone looking to upgrade their ride's performance.

The Load Assist Kit comes with

  • 2 x BOSS Extreme Series Double Bellow Airbags
  • 4 x brackets (2 upper & 2 lower)
  • Mounting Hardware
  • Quality SAE J844 Government Approved Airline
  • Dual Schrader Valves Mounted in Stainless Panel
  • Instructions for fitting

Had a warranty issue with installation and supplier ignored my request

Hi Wesley,
Please accept our sincere apologies for your negative experience.

After seeing your review, I went looking for your original support request as we were certain we hadn’t received anything from you. Unfortunately, we discovered that your email had been filtered into our spam folder, which is why it was missed. I’m very sorry that this happened.

We take customer support very seriously and always aim to respond quickly, so I completely understand how frustrating this must have been from your side.

If the issue with the installation is still unresolved, please let me know and I’d be more than happy to assist you and help get it sorted.

Why Shop at 4x4 Down Under?

We know that you have a lot of options out there, and we’re incredibly grateful that you’re considering spending your hard earned money with us. We like to think we stand out from the crowd in a few ways.

Excellent & Honest Service

We try and provide the best pre and after sales service possible. If you have a question we’re here to help, and if we don’t know the answer we’ll tell you and then do our absolute best to find the answer for you. We’re also here to guide you to the best possible outcome for you. A lot of stores will simply try to up-sell you on the most expensive option. That’s not how we operate. We want to build a relationship with our customers, and the only way to do that is by being honest and direct.

4x4 Down Under is built on honesty and integrity. For example when you make a purchase with us we only charge your account once we confirm the product is ready for dispatch. Although we like to guarantee everything on our store is available we’re not perfect and mistakes do happen. If something turns out to not be available we’ll let you know immediately and you have the option to cancel your order or wait for more stock to arrive. Should you not want to wait the order is voided, and there’s no waiting a week to get your money back (it’s instant!).

Aussie and Proud!

We're Australians, and we like to support our fellow Australians, which is why all our products are sourced locally from the official Australian distributors. Nothing is imported directly and we don't stock any grey imports. This also means that all manufacturer warranties are fully honored by the brands themselves.

No Sales Gimmicks 

When you shop at 4x4 Down Under you don’t have to worry about:
  • Annoying and dishonest ’Sales Timers’ that simply reset every few hours and are there to coerce you into buying.
  • Dishonest “low stock” labels, another coercive sales gimmick.
  • False “John just bought a…” alerts. Our customer alerts (bottom left) are 100% true and we're proud of them.
  • Being bombarded by trust badges and labels everywhere you look that mean nothing. 
  • We don't spam! Your information is safe with us. It will never be shared or sold, or used to fill your inbox with garbage.

Fast Shipping with Insurance!

We've partnered with some of Australia's best couriers and freight agents to ensure your purchase reaches you in super-quick time. Once your order has been dispatched you'll receive tracking information which will allow you to track your order online every step of the way. And if something should happen to your order while in transit you can rest assured that it's insured and you won't lose a dime!

If you still have any doubts feel free to give us a call on 1300 76 86 41, or contact us here. We'd love to hear from you.
