4WD Modifications - Suspension and Brakes
Very few standard suspensions are suitable for bush work; we guide you through the maze of aftermarket suspension choices. We also cover the important topic of brakes.
25 SUSPENSION MODIFICATIONS
A guide to the most popular suspension modifications.
After bar work and roof racks the most common modification made to a 4WD is done underneath – to the suspension. We’ve separated different suspension types and listed the ideal changes needed for each type.
BILSTEIN SHOCK ABSORBER LONG-TERM TEST
We haven't been able to kill these dampers - September 2016
We fitted a test set of Bilsteins to the Outback Travel Australia LandCruiser 75 Series exactly 85,000km ago. Since then they’ve done five major bush trips at a full 3.5-tonnes GVM on some of the worst roads and tracks in the Outback.
BILSTEIN SHOCK ABSORBERS FOR TRAILERS - March 2015
These famous dampers are now specified for camper trailers and caravans.
Bilstein shock absorbers are well known for their high-performance damping abilities on 4WDs and now there's a revalved range to suit single and dual mounting on caravans and camper trailers.
DOBINSONS MONOTUBE DAMPER RANGE - February 2016
Not yet a household suspension name, but homegrown and high-tech nonetheless.
Dobinsons has released a 2016 range of MRR monotube remote reservoir shock absorbers. All are re-buildable and re-valvable, and are direct bolt-in replacement units.
IRONMAN HILUX SUSPENSION
Ironman 4x4 has suspension kits for the 2016 HiLux - February 2016
Ironman 4x4's suspension kits have been designed to improve ride quality and load carrying ability, while providing an increase in ride height, with the choice of Performance, Constant Load or Extra Constant Load settings.
KONI SHOCK ABSORBER EVALUATION
Not our normal test procedure and with mixed results - February 2018
We asked the Australian Koni distributors, Toperformance Products, for a set of dampers to test on our LandCruiser 75 Series, but they refused, so we’ve used OTA Team vehicles for the purpose.
NEW 2015 SUSPENSION RANGE FROM OPPOSITE LOCK
Aussie-made springs and a choice of two damper types.
The Opposite Lock Group has released a new range of premium quality suspension kits, with a warranty period of three years or 60,000 kilometers.
SUSPENSIONS - WHY MUCK AROUND WITH THEM
A 4WD novice may not see the need, but experienced off roaders know better
Apart from air-suspended 4WD wagons we can’t think of any stock 4WD that won’t benefit from suspension modifications that can improve load carrying capacity, off-road ability, ride quality and handling
TJM FOX SHOCKS
TJM has entered the monotube arena - November 2017
At Outback Travel Australia we’re big fans of monotube shock absorbers. All our testing over the past 20 years shows that they have better bump and rebound control than twin-tube types, run cooler and fade less.
TJM XGS 4000 SUSPENSIONS
TJM has expanded its range of compliant suspension kits - September 2016
TJM XGS Series 4000 Suspension Kits have been engineered to improve every aspect of 4WD ride, handling and load-carrying ability. New models are being continually developed.
