Check the suspension components when you are looking to purchase a used diesel lifted trucks. Lifting a vehicle can drastically change its handling characteristics.
Outdoor enthusiasts can gain more confidence when navigating rough terrains. For professionals, it can mean better towing capability. For others, it’s simply a matter of style.
Engine
If you’ve ever watched a massive truck haul a huge load up a hill, you likely marveled at the immense power that these machines generate to overcome the forces of gravity. What you may not have realized is the incredible power source that makes this process possible: a diesel engine.
Diesel engines provide the power for some of the world’s biggest trucks, trains, submarines, and ships. Diesel engines are similar to gasoline engines but have an advantage in heavy-duty applications.
The main reason is that diesel engines are more powerful than their gasoline counterparts. They can lift and move large objects with ease. Diesel forklifts work well in outdoor environments because they produce more torque.
Diesel engines, like any other engine type, require regular maintenance. The good thing is that the majority of major lift trucks manufacturers have service centres that can perform this task with relative ease. This reduces downtime and repair cost over the lifetime of the lift truck.
These services are not only for routine maintenance but can also be used to identify issues that affect performance or fuel efficiency. These problems can be corrected or fixed before they become major issues, saving you time and money.
These service centers also provide access to experts that know how to troubleshoot, and repair, the complex systems in modern lift trucks. This allows you to maximize productivity by minimizing downtime and repair costs.
Suspension
The suspension is a vital part of the vehicle that enhances stability, control, and comfort both on and off road. It is composed of a number of different components including springs and shocks or struts. The springs absorb impacts and support the weight of the vehicle, while the shocks or struts dampen vibrations and maintain tire contact with the ground for optimal handling. The track bar, swaybar and other components improve the articulation between the wheels to help the truck navigate rough terrain.
Suspension upgrades are popular with diesel lifted trucks because they increase the ride height and allow for larger tires, which in turn increases off-road capabilities. You should choose a suspension system that will not affect your ride too much, and is suitable for the type driving you do.
If you’re interested in upgrading your suspension, it’s best to work with a professional to ensure the upgrade is optimized for off-road driving. They can also give you advice on maintenance and inspection.
A body lift kit can be a simple and inexpensive way to raise your truck’s ride height without affecting its off-road capability too much. These kits involve adding spacers, usually between the frame of the truck and the chassis. This will raise the ride by 3 to five inches. This allows for larger tires and improved ground clearance, but it’s important to note that the increased height will also affect your center of gravity and could lead to handling issues.
Air shocks are another popular option for lifting your truck while still maintaining a reasonable load carrying capacity. They look similar to traditional shocks but use air instead of oil to adjust the ride height. Air pressure can be adjusted to your specific needs, making these shocks a great choice for people who frequently haul heavy loads.
If you notice a bumpy ride or that your truck leans back or to the side when braking, it may be time to service the suspension. This will restore your truck’s performance and reduce wear. It’s important that you re-gear your differential if you plan to change the size of your tires. This will maintain your off-road capabilities and prevent damage to your transmission.
Brakes
Everyone loves horsepower and 0-60 times, but a truck’s braking capability is just as important. When it comes to hauling heavy loads, brakes are vital.
It’s important to know the problems with braking systems, whether you are a fleet manager or a driver. This allows you to identify problems before they escalate, making it easier for you to do your job and ensuring the safety of your car.
The brakes on a lifted truck will be under more strain as they are supporting more weight above their tires. This means that it takes longer for the brakes to impact the wheels and slow down the truck. The increased rotational mass can also cause overheating. To counteract these factors, many companies sell brake kits that feature bigger rotors and pads to help the system cope.
Wilwood’s Big Brake Kit is a great upgrade. This bolt-on set includes TX6R calipers with massive 15″ GT-60 directional rotors and BPQ compound pads. It’s designed for extreme duty performance in high heat conditions.
Another great way to increase the braking power of your lift truck is by installing an exhaust brake. This works by using engine compression to slow the truck down. This is the same type brake you hear on large diesel truck when they descend steep grades. While most diesel truck drivers don’t use their brakes nearly as much as they do service brakes, exhaust brakes can be an important safety accessory for those hauling heavy loads.
The steering system must be upgraded on a lifted diesel truck to support the added front gross axle weight rating. To ensure the safety of the load, it is important that all hoses, lines and calipers are in good condition. The power steering pump, as well as the linkages, are upgraded to handle increased pressure. The larger pumps produce more fluid and better pressure to reduce steering effort. This makes it easier to steer the truck at low speeds and during parking or turning.
Tires
The tires on a diesel-lifted truck are important for the way the truck drives. The right tire can help with traction, stability, and fuel efficiency. It can also make an important difference in the way your truck performs on and off-road.
Different terrains and driving style will require different tires. Mud tires are the best for off-roading, as they have a large tread pattern that digs into ground to provide grip. Highway terrain tires have a less aggressive tread pattern and a smoother tread to handle highway speeds while providing good traction on pavement.
When choosing a truck tire, pay attention to the tread wear and ply ratings. Poor quality tires can lead to uneven wear which can cause vibrations in the entire vehicle. If the tires are deflated, they can be difficult to control and have less grip.
It’s also important to take into account the size of the tires. The larger tires are more costly, but can improve handling and grip. They can also increase the resale value of your truck. When selecting a tire size, it’s also important to consider the wheel backspace, which is the distance between the wheel mounting surface and the inner bead lip.
Another factor to consider is the effect that larger tires have on the truck’s braking, handling, and acceleration performance. The gearing of your truck can be upset when you install larger tires. This can result in worse fuel economy and can cause your speedometer to be inaccurate.
You should also keep in mind that you may need to re-gear your axle if you plan to do a large lift on your truck. The reason for this is that manufacturers design their gears in order to balance power and torque with fuel economy, based on stock tire sizes. When you add bigger tires, you may need to reduce the gearing to maintain proper drivability and towing capability.
