Boss Extreme Series Airbag Suspension Kit for Standard Height or 1" Lift Utes
Upgrade your ute with Boss Extreme Series airbags, designed to handle tough loads with ease. Rated at 2500lb (1136kg) per side and government-approved for testing over 750psi, these airbags are built to last and provide reliable support. Manufactured in-house and branded Boss, you can trust their quality—don’t settle for unbranded alternatives often found from overseas.
For most dual cab utes, air pressures range from 15-45psi depending on the load. With over 13,000 load assist kits sold across Australia, our airbag suspension systems are trusted by 4WD enthusiasts, miners, tradies, tour operators, and more. Whether for agricultural vehicles, trailers, or motorhomes, these airbags are versatile and proven performers.
To get the best ride, simply inflate the airbags enough to achieve a level ride height. This helps distribute the load across your suspension components, reducing unnecessary strain on any single part.
Suits: Standard height utes or those with up to a 1" lift.
Note: If your vehicle has a 1-2" pre-fitted suspension lift, our LA-47 kit will be the best fit for you.

The winch is good but had to upgrade the wiring that came with it. The winch hit a peak of 125 amps pulling my 5 mtr side console onto the trailer.
It seemed to do it easy, but the standard wiring was way too hot afterward for my liking.
I use my boat a lot so I wanted to make sure the winch could pull all the power it wants with no issues.
Batteries supplying the winch are 2 x 200-amp hour lithium’s (LifePo4) wired in parallel that give a combined continuous peak amp output of up to 205 amps for 5 mins.
Upgraded all the wiring to 0 AWG ultra-high current marine power cable capable of handling 200amps and changed over to 175 amp rated Anderson plugs.
Housed the solenoid and rocker switch in a waterproof switch box with cable glands for cabling and mounted it to the trailer.
It wasn’t cheap at around $600 for the upgraded cabling, terminal lugs, heat shrink and waterproof housing, but it was well and truly worth it.
Went away fishing and put the boat on and off the trailer everyday for 8 days. At one particularly steep ramp with wind and current playing havoc the winch didn’t miss a beat.
