Frequently Asked Questions
Wouldn't it be better for me to purchase a halogen bulb with higher wattage, instead of buying HID bulbs?
HID lamps are 35 watts, while standard halogen bulbs are 55 watts. Although, HID bulbs work with fewer watts, they still produce 3x more light. The higher wattage halogen bulb will be brighter than a 35W bulb but still much dimmer then the HID bulbs.
What is required to clean and maintain a Roll-N-Lock cover?
The cover requires occasional treatment with RaggTopp Vinyl Protectant, a bottle of which is packaged with every Roll-N-Lock cover. It should be applied each time you wash your truck.
Is Roll-N-Lock a watertight application?
In a word, no. Roll-N-Lock is a movable system, making it almost impossible to achieve absolute water tightness. However, properly installed, Roll-N-Lock is a reasonably dry application. Some dripping can occur when parked in a continuous rain. This is generally at the tailgate area. Some applications are more problematic in this regard due to unusual bed configurations. Conditions on the Ford Flareside and Supercrew applications cause the tailgate to be more susceptible to dripping than conventional applications.
How strong is the Roll-N-Lock cover, how much weight will it hold?
The Roll-N-Lock cover will withstand a concentrated load of about 120 pounds. In other words, standing on the cover could cause visible damage. However, damaging the cover with even twice the amount of force referred to does not mean that a forced entry can be achieved. The result would simply be deformation of the cover body. A distributed load, such as snow, is easily managed.
Is your product waterproof?
Not waterproof, but water-tite.To insure cargo protection from outside elements,a double seal perimeter gasket is installed all around with the front part having a flap that extends between the front bulkhead and the truck cab. This flap provides additional protection when opening the cover when water is on it and also while you are traveling in in climate weather.
Will drilling be required to attach a Roll-N-Lock to my truck?
Drilling on most trucks is limited to the tailgate only, as the primary attaching means is accomplished with Roll-N-Lock's patented clamp-on track system. Attachment of the tailgate extrusion (tailgate locking closure strip) requires five small, self-drilling screws, which are tucked neatly within or under the extrusion. The Dodge Ram, Ford Sport Trac, and Ford Supercrew require minimal drilling into the down flange of the bedrail. The Ford Flareside is the exception, requiring coupling flanges which are screwed on to the bed rails.
Can I add accessories (i.e. spoiler, bike rack, rail bars, etc.) to your product?
Yes, however, any additions/modifications will void the warranty. If you do decide to add to your cover call our factory for advice as to where to drill and what size holes will be required for specific size fasteners.
Will the TruXedo® Lo Pro QT work in the winter as well as in the summer?
The tonneau cover fabric will not shrink in cold temperatures, to –40 degrees F. Patented automatic tension control system keeps the cover tight whether it is 40 degrees below or 120 degrees above. Sliding Velcro® brand hook on the side rail works with the automatic tension control plungers to keep the cover tight – even when it’s closed!
How do I adjust the tension on my tonneau cover?
The TruXedo® Lo Pro QT tonneau cover has automatic tension control. There are two spring loaded steel plungers at the front of the bed that maintain constant tension on the front header, allowing the cover to stay tight in any weather. Initially, you need to set the tension. This should be done during the warmest part of the day by closing the cover, releasing the Velcro® brand fasteners from both sides near the cab, and checking compression of the spring plungers against the front header. Roll cover open to make adjustments. Repeat until satisfactory tension is achieved. Refer to the TruXedo® Lo Pro QT Owners Manual for more specific information.
Can I lock the TruXedo® Lo Pro QT?
The TruXedo® Lo Pro QT secures automatically when latched at the rear, and provides added security when used with a locking tailgate. It can not be opened until the tailgate is unlocked and opened. There are no additional locks or sliding mechanisms needed to lock the cover.
What are the advantages of a MBRP exhaust compared to the stock?
By installing an MBRP exhaust system you will see an increase in horsepower, torque, fuel mileage gains may be noticed and a decrease in exhaust gas temperatures (EGTs). By lowering EGTs you will increase your turbo longevity.
What improvements can I expect in torque, HP and temps?
While performance gains vary depending on the vehicle you can expect a gain of 5% to 10% in horsepower and torque. For example, with a 2005 Chevrolet Silverado with a Duramax diesel engine you will see a gain of 18 HP. and 28 ft/lbs measured at the rear wheels. You can also expect a reduction in exhaust gas temperature (EGT) by approx 200º F.
I bought a smoke bug deflector for 2008 Chevy Silverado 2500HD, and after installing it, my truck makes crackling sound at top of the windshield at highway speeds...really annoying, was wondering if there is a recall, or some kind of fix offered?
I recently purchased a Stampede bug shield for 2008 F150. After the install the wind noise is horrible. The hood shakes, the wipers vibrate, etc. Is it installed wrong or is this characteristic?
If you watch closely you will see that Ford F150 hoods after 2004 were manufactured out of a lighter composite material, therefore the hood now bounces where the hood meets the windshield. This happens without a bugshield installed; when a bugshield is installed it can aggravate an existing problem. Stampede recommends using a very low profile shield and taking your vehicle back to the dealership to have them fix the hood issue as described in the attachment. Attached is the Notice From Ford on the issue.
What kind of maintenance needs to be done to the 5th Wheel Hitch?
Can I install over a bed liner?
Do not install mounting rails over plastic bed liners. Plastic bed liners must be cut out of the way. Base rails may be installed on spray in liner. Note: Consult installer for recommended curing time.
What is a lube plate or a slip disk?
How Large a Trailer Can I Tow?
GCW - GVW = Max. GTW
GVW = Actual weight of the vehicle when fully loaded. It is the base curb weight plus the cargo weight.
GTW = The weight of the trailer fully loaded.
What capacity can I pull with my vehicle?
Different vehicles have different towing ratings or capacities. Please refer to your vehicle owner’s manual or contact the manufacturer to find your vehicle's capacity.
When do I need to use weight distributing? / What is weight distributing?
Anytime you are above the Weight Carrying (WC) rating of your Class III/IV Receiver or you want to improve the ride quality and "towability" of your tow vehicle and trailer combination.
Can I have a different air pressures in each air spring?
The ability to compensate for off-center loads is one of the best features of the air spring. Yes you can have different pressures in each air spring.
Will the air helper springs stabilize my vehicle?
Yes, the more air pressure you add the less vehicle movement you get in return.
Where should I mount the inflation valves?
The inflation valves should be mounted in an easily accessible location. We recommend placing the inflation valves on or around the rear bumper.
Do the air springs improve the ride?
When the vehicle is loaded, the air springs help the existing suspension carry the load and improve the ride a great deal.
What's included in the basic kit?
Nuts, bolts, brackets, air springs, air line and manual inflation valves. Everything is included for a manual inflation system.
How much air pressure should be in the air springs?
Air Pressure requirements vary from application to personal preference.
Do the air helper springs replace the existing suspension?
The air springs maximize a vehicles carrying capacity within the vehicles GVWR. Do not overload the vehicle.
