Our Services

Oil & Transmission Coolers

Is your radiator struggling to keep your vehicle cool? If so, it’s time to upgrade to a solution that uses both oil and transmission coolers. These coolers function by dispersing heat from the oil and transmission fluid, similar to how radiator systems dissipate heat from engine coolant. This prevents overheating when hauling heavy loads, especially in terms of driving uphill or on uneven land. Overheating can inflict serious harm to an engine, including damaged pistons and blown head gaskets. Upgrading to a system that incorporates transmission and oil coolers ensures your vehicle’s well-being and performance when taking care of large loads.

Chassis Adjustments

Multiple brands of basic truck chassis are available in the market. While these chassis are suitable for most purposes, there may be times when a customized or specialized chassis is required for certain applications. This happens when a standard chassis is not enough to meet the outlined specifications.


Generally, a turbocharger is placed in a diesel engine during the manufacturing process. If you believe that your truck or fleet lacks power, you can choose to replace the existing turbocharger with a bigger one and allow it to carry heavier loads. Note that a bigger turbocharger demands more cooling, so you should upgrade the coolant system when you change the turbocharger.
