If I install the Dual Range, will it void my vehicle warranty?
No, the addition of the Dual Range doesn’t void your vehicle warranty. Automotive manufacturers such as Dodge, General Motors, Ford, Freightliner, and Spartan have publicized the fact that the addition of aftermarket products does not void their warranties. There has been a lot of confusion about this issue, but federal law actually prohibits manufacturers from voiding warranties based on the addition of aftermarket parts unless they can prove that the aftermarket item caused a failure in the vehicle.

What is the warranty on the U.S. Gear Dual Range?
U.S. Gear warrants the product from defect for one full year, with unlimited mileage, from the date of purchase. The warranty covers 100% of parts, 100% of labor, and all freight charges. A copy of the written warranty is included with each product.

What is the ratio of the Dual Range?
The Dual Range is available in two different models: Direct and 20% Overdrive or Direct and 20% Underdrive. The 20% overdrive ratio is .80 and the 20% underdrive ratio is 1.25.

How does the Dual Range work?
The Dual Range works exactly like an electric 2-speed axle commonly found in commercial trucks. The Dual Range bolts directly to the back of your factory transmission giving you the equivalent of two axle ratios or twice the transmission ratios (gear splitting). At the flip of a switch, you can select a high speed ratio for highway cruising or solo driving, or you can select a low range for highway towing, city driving, or mountain terrain. Shifting back and forth from high range to low range can be done at any speed (shift-on-the-fly).

How does the Dual Range compare to the competition?
The U.S. Gear Dual Range is the only American-made, electric-operated auxiliary transmission in the industry. It has the heaviest GVCW rating (35,000#) and is the only auxiliary transmission available as either overdrive or underdrive. The Dual Range is also priced $500-$800 less than the competitors. The Dual Range is the only unit that has no limitations on how it is used. It can be used in forward or reverse, 2 or 4 wheel drive, uphill and downhill. No other auxiliary transmission manufacturer can say that.

What vehicles will it fit?
The Dual range will fit all Dodge, GM, and Ford full-size pick-ups, vans, Suburbans, class C and class A motorhomes with automatic or manual transmissions, 2 or 4 wheel drive.

Is installation difficult?
Installation of the Dual Range always requires shortening and balancing of the drive shaft. In most applications, this is the only modification required; however’ on occasion modifications may be necessary to the exhaust system, floor pan, and in some 4WD applications, modification to the fuel tank. The balance of the installation is a simple bolt-on and wiring the driver control that is supplied in each kit.
