IF YOU’RE GOING BUSH, BOUNDING OVER A BUMPY BUILDING SITE OR HAULING A CARAVAN ACROSS THE COUNTRY, TJM HAS A SUSPENSION SYSTEM TO SUIT YOUR 4WD.
If wheels were your car’s feet, then suspension would be the legs. Just as the strength, length and flexibility of your legs impact on the way in which you move and the way you connect to the ground, different types of suspension determine the functionality, safety and comfort of your vehicle on different terrain. Made up of several parts that work together like joints and bones, suspension affects absolutely every aspect of driving. Given the importance of suspension, it’s surprising how frequently people place priority on installing bull bars, roof racks and other 4WD accessories without even considering their suspension needs.
Whether you’re tackling corrugated roads, rough terrain, or you need to tow a caravan, the right TJM suspension will contribute to the car’s road handling, braking ability, cushion the ride from bumps, noise and vibration for occupants and protect the vehicle and its contents fromwear and tear.
4WD’s have factory-engineered suspension, but it’s usually only enough to accommodate a boot load of gear and general road driving or limited off-road driving. Installing a set of shock absorbers, a pair of springs or a full TJM XGS suspension kit will immediately transform your vehicle’s ride, handling, load carrying and towing capabilities. So don’t forget to talk with your local TJM distributor about your individual suspension needs.
Shock Absorbers reduce the effect of traveling over rough ground, leading to improved ride quality and vehicle handling. While shock absorbers serve the purpose of limiting excessive suspension movement, their intended sole purpose is to damp spring oscillations. Shock absorbers use valving of oil and gasses to absorb excess energy from the springs. Spring rates are chosen by the manufacturer based on the weight of the vehicle, loaded and unloaded. Some people use shocks to modify spring rates but this is not the correct use. Along with hysteresis in the tire itself, they damp the energy stored in the motion of the unsprung weight up and down. Effective wheel bounce damping may require tuning shocks to an optimal resistance.
Spring-based Shock Absorbers commonly use coil springs or leaf springs, though torsion bars are used in torsional shocks as well. Ideal springs alone, however, are not shock absorbers, as springs only store and do not dissipate or absorb energy. Vehicles typically employ both hydraulic Shock Absorbers and springs or torsion bars. In this combination, “shock absorber” refers specifically to the hydraulic piston that absorbs and dissipates vibration.
