How DRP Can Help Maximize Your Trucks Performance
-
Reduce bearing drag caused by bearing preload
Bearing preload causes tremendous drag on your hubs, robbing your truck of horsepower and fuel economy.
​
-
Reduce tire drag & wear
Bearing end play fixes the preload problems, but causes steering instability and tire scrub, increasing tire wear and drag. Our patented adjustable Hub Defenders allow you to set your hub bearings to the perfect balance of zero preload and .001" end play.
​
-
Reduce maintenance costs caused by bearing failure
Bearing preload and excessive end play causes bearing and seal failures. Our patented adjustable Hub Defenders and high performance bearing kits run cooler and lessen maintenance.​
​
-
Deliver you valuable data
We don't assume or guess, we test and measure. Our expertise in building custom test equipment and data acquisition can deliver you the data needed to make better decisions. ​
​
-
Save you money with rebuilt hubs vs. replacement
Many of the "pre-set" hub options available require complete replacement of the hub assembly. DRP patented adjustable Hub Defenders and set up tools allow you to rebuild hubs to a higher tolerance than when they were new! Save money and increase performance. ​
Data Driven!
We invest tremendous time and resources to test components in a laboratory setting, simulating real-world conditions as much as possible. Controlled environment testing allows direct monitoring and measurement of individual components, eliminating variables. While lab testing is great for precise measurements, real-world testing is important to validate the data. We utilize our advanced data and acquisition systems to record hub temperature, hub RPM, and even hub play while on the road!
No assumptions, no guesswork
Patented adjustable Hub Defenders
Adjustable bearing spacer technology has been tested and proven in markets from heavy hauling and earth moving in Australia to NASCAR® here in the U.S.A. for over 15 years.
