  • Is the Hopkins Tailgate EasyLift Compatible with an LED Light Bar Under the Tailgate
  • Light bars can sometimes interfere with the installation of the Hopkins Tailgate EasyLift, # 74211. I spoke with my contact at Hopkins to see if they know of any fit issues with a light bar and he told me they did have some reported complaints about light bars interfering on Dodge trucks, but he did not have any information on GM trucks. I do have some information that will help determine if the EasyLift will fit with your LED light bar. To install the EasyLift on your truck, you will...

  • Will the TracRac SR Work with a Truxedo Tonneau Cover on a 2007 GMC Sierra 1500
  • The TracRac SR Sliding Truck Bed Ladder Rack part # TH43002XT-501 works with most soft tonneau covers mounted inside the bed rails on your 2007 GMC Sierra 1500 as the TracRac SR mounts to the top of the bed rails. If you can provide me with the exact Truxedo tonneau cover you have installed on your vehicle, I would be glad to offer a more precise recommendation.

  • Front Mounted Receiver Hitch for 2007 Sierra Classic
  • Unfortunately, the frame with isn't the only consideration. According to Draw-Tite, the differences in the way the front bumper, fascia and grill are situated in regard to the front of the frame members on a 2007 Classic versus a 2007 New Body will prevent the # 65050 from being installed on a 2007 GMC Sierra Classic without extensive modification to the vehicle. I've provided a photo showing how the front clips are different on the 2 vehicles. For your 2007 Sierra Classic, I'd recommend...

  • Hi Rise Hitch Compatibility with 2006 Chevy Sierra Dually Crew Cab
  • The Hi-Rise Gooseneck-to-5th-Wheel Trailer Hitch Adapter # 9480 is not a confirmed fit for every gooseneck hitch. The B&W hitches and the Under-Bed by Bulldog are confirmed to fit as well as the Hide-A-Goose hitches # 9460, # 9464, and # 9465. Any other hitch may or may not fit. There are not other adapter options for other fits. If you have a different gooseneck hitch, you may need to instead use the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter - Single Jaw - 21,000 lbs...

  • Prodigy P2 Upgrade Using Prodigy Original Wiring Harness
  • The original Tekonsha Prodigy brake controller had the same wiring connection as the newer P2 # 90885 and P3 # 90195 units. If you wish to use the hardwired pigtail, it will be directly compatible with these units for an upgraded brake controller so you can simply plug and play. Since your vehicle has the factory tow package your can alternatively use the wiring adapter # 3015-P. The custom connector end plugs into the electric junction box beneath the dash of your vehicle and the other...

  • Will The Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter Work With A B&W Gooseneck Hitch
  • As long as the B&W gooseneck hitch is compatible with a 2-5/16" hitch ball, then yes, the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter part # CAB-C5G will work for you. To secure this adapter, I recommend using the Master Lock Covered Solid Body Padlocks part # 141T. If you do not already have a 2-5/16" hitch ball on your B&W gooseneck trailer, I recommend using the Replacement Hitch Ball for B&W Turnoverball Underbed Gooseneck Hitch part # BWGNXA2006. I have attached a review...

  • Is Curt Trailer Hitch 14108 a Fit for a 2007 GMC Sierra 2500HD Classic 6-1/2 Bed
  • Yes, I confirmed that the Curt 2" Trailer Hitch Receiver # C14108 is a fit for your 2007 GMC Sierra 2500HD Classic with the 6-1/2' bed. If you need a wiring connector then I recommend the Hopkins # HM40975 which will be an exact replacement to fit in the bumper cutout (if that's what you have). If you don't have the bumper cutout then this can be attached to the trailer hitch using the mounting bracket # 18136. To complete your towing setup you also need a ball mount. For that I recommend...

  • Will New Replacement Trunnions Fit Very Old Reese Spring Bars and Weight Distribution Head
  • Reese has told us that the modern Reese trunnions will not fit the old style weight distribution heads. You would have to also replace the head. Since you would need to replace the head and the spring bars you might as well replace the whole system. We have a lot of systems that will work with a trailer with 1,100 pounds of tongue weight. Equal-I-zer system # EQ37140ET for example is rated to 1,400 pounds. I have also included a link to all of the systems we have that would be good for...

  • Correct JT's Strong Arm Jack Stabilizer Kit for a 2021 Forest River Aurora Travel Trailer
  • We do have what you need but the reason everything seems off compared to what you have is because the JT's Strong Arm Jack Stabilizer Kit # LC191023 is designed for use on 5th wheel trailers. Since your Aurora is a travel trailer it is going to have a different set up and you would want the JT's Strong Arm Jack Stabilizer Kit for Travel Trailers # LC191025. The # LC191025 attaches to traditional stabilizer jacks, scissor jacks, and/or landing gear. If you have electric jacks you would...

  • Correct Timbren Suspension Enhancement for 2007 GMC Sierra 1500
  • While we have the correct fitting Timbren Suspension Enhancement for your truck, whichever information you saw was incorrect if it said model DR1500DQ would fit your 2007 GMC Sierra 1500. As noted on our website, that model only fits certain model year Ram trucks. The correct fit will depend on if your 2007 GMC Sierra is the Classic or New Body style: 2007 GMC Sierra 1500HD Classic (4WD or 2WD) - Timbren Rear Suspension Enhancement System # TGMRCK25S 2007 GMC Sierra 1500 New Body (4WD...

  • Stromberg-Carlson 5th Wheel Tailgate Fit on 2007 GMC Sierra 3500 Duramax Dually
  • Your 2007 model year Sierra was offered with a choice of body styles so this will affect the fit of an aftermarket 5th wheel tailgate like the Stromberg Carlson # VGM-07-100, which fits the new body style. Part # VGM-99-4000 fits the old body. My contact at Stromberg Carlson suggested you take a few measurements to confirm the correct tailgate for your truck. The linked photo shows the three points to measure on the existing tailgate. In a separate email I have sent the Stromberg Carlson...

  • Recommended Air Springs For A 2007 GMC Sierra With In-Bed Hitch And 2 Lift
  • For your 2007 GMC Sierra 2500 with in-bed hitch and 2" lift I recommend the Air Lift LoadLifter 5000 Ultimate Air Springs w/ Internal Bumpers # AL88275 along with the Air Lift Universal Air Spring Spacers # AL52420 to fill in the 2" gap. These air springs have internal bumpers to provide the adjustable load support of air springs and the comfort and reliability of jounce springs. The durable stainless steel roll plates, air lines, and hardware are all rustproof. These springs have a...

  • Replacement 5th Wheel Base Rails for 2007 GMC 2500HD
  • The Reese Universal Base Rails for 5th Wheel Trailer Hitches - 10 Bolt # RP58058 are my recommendation is you have Reese rails to replace. If you have Curt rails to replace then the Curt Universal Fifth Wheel Base Rails - Gloss Finish # C16104 but you will also want the Replacement Hardware for Curt Universal 5th Wheel Installation Kit - 10 Bolt # C16111. You don't want to mix the bracket and rail brands. Either option will work with the gooseneck plate you referenced as they are industry...

  • Compatibility of B&W Trailer Hitch Receiver with 285/70-17 Spare Tire
  • The B&W Heavy-Duty Trailer Hitch Receiver - Custom Fit - Class V - 2" # BWHDRH25182 is shown with the factory 245/70-17 tire which has a 30-1/2 inch diameter. The 285/70-17 tire you mentioned is 32.7 inches diameter so it hasn't been tested to confirm, but it does appear will fit because of the mount style but the tire will most likely rest the tread against the crossbar.

  • Would Bed Liner From 2009 GMC Sierra fit 2007 GMC Sierra Classic Body
  • There was a big enough difference between the new and classic body styles of the GMC Sierras that a bed liner from one would not fit the other. So for the 2007 GMC Sierra Classic short bed we have the part # BRC99SBK if you were looking for something that would fit and provides excellent protection for the bed of your truck.

  • 5th Wheel Tailgate for a 2007 GMC Sierra 2500HD
  • 2007 was a split year for the GMC Sierra. There were Classic models that had rear amber turn signals. And there were New Body style that had all red tail light assemblies. If the truck is a Classic then you can use 5th wheel tail gate # VGM-99-100. If the truck is the new body style use # VGM-07-100.
