Q:  Do you have this part in stock?
 Items with the "Quick Ship" logo are in stock at our own warehouse and ready to ship without relying on the manufacturer to ship directly to you. In many instances, depending on the size of the package, we will even ship your product via a faster shipping method than you initially selected so you get your parts even faster!

For items sent directly from the manufacturer, if we are aware there is any kind of lead time we do our best to have each product marked directly below the Add To Cart button. However, sometimes we don't know until a product is ordered. In those cases, we will typically contact you with options in 1-2 business days.

 Q:  How long will it take to get the part I ordered?
 Shipping speed depends on your chosen shipping method. We have several shipping options ranging from Free Economy Shipping to Next Day Air. Keep in mind ALL orders have a processing time. You are paying for the shipping service from when the order ships, not from the order date. We do our best to get all orders out the same or the next business day.

 Q:  What is the difference between custom tuning and box tuners like the Edge Evolution?
A: Custom tuning and box tuners are both methods to adjust the performance characteristics of your diesel truck, but they differ significantly in their approach and level of customization.

Custom tuning involves a specialist tailoring your vehicle's electronic control unit (ECU) settings to match your specific hardware upgrades, driving style, and performance goals. This process accounts for every detail of your vehicle's setup, resulting in optimal power, torque, and efficiency. However, this service requires specialized knowledge and can be more costly.

Box tuners, like the Edge Evolution, are off-the-shelf products that offer pre-set tunes. These devices are user-friendly and usually come with several settings to choose from, such as economy, towing, or performance modes. While they can't provide the same level of customization as a custom tune, they're often sufficient for minor to moderate upgrades and tend to be more budget-friendly.

 Q:  I have a bad injector in my diesel truck, can I just replace one?
A: Yes, it's possible to replace only the faulty injector if you're in a pinch. However, it's generally recommended to replace the entire set of injectors at once as the other injectors are likely to have similar wear levels, and a single new injector among older ones could result in uneven performance. Replacing all injectors at the same time can also prevent you from having to repeat the labor-intensive process multiple times as other injectors may fail in the near future.

 Q:  Can you explain the differences between organic and ceramic clutch materials, especially in terms of drivability?
A: Organic clutches are generally made from friction modifiers, such as metallic powder, metal oxides, and sometimes even fiberglass to enhance durability. On the other hand, ceramic clutches predominantly consist of copper, iron, and graphite.

In terms of drivability, organic clutches are the go-to choice. Their material offers a gradual grip, leading to smoother shifts and consistent wear. Conversely, ceramic clutches have a friction material that grabs almost instantly, which might lead to a more abrupt or harsh shift.

 Q:  When is it time to re-gear my diesel truck's axles?
A: If you've installed larger tires on your truck, it's a good indicator that you may need to re-gear your axles. Bigger tires alter factors like rolling resistance, diameter, and overall weight, which puts extra demands on your drivetrain. To enhance your truck's performance and alleviate this additional stress, adjusting to the right gear ratio is crucial. For tailored advice that suits your specific vehicle and situation, speak with one of our diesel experts today.

 Q:  How do I determine the right drop hitch size for my diesel truck?
A: To accurately gauge the drop hitch size you need, start by parking your truck on a flat surface. Measure the height from the ground to the top interior of your hitch receiver. Then, measure the distance from the ground to the bottom of your trailer coupler. Subtract the first measurement from the second one to get the required drop hitch size.
