Hey Gregory, thanks for reaching out! I really like the etrailer Trailer Hitch Receiver #e55ZR as well - I know you'll be happy with it! When it comes to wiring, a 4-Way is used for basic trailer lighting, but since you'll be towing a trailer…

Hello Murray, thanks for reaching out. That appears to be a Westin HDX grille guard. The Replacement Hardware Kit for Westin HDX Grille Guards #57-227PK is what will fit the 2008 Chevy Silverado 2500HD. These HDX grille guards are not universal…

Great question, Jay! The Air Lift WirelessAIR Compressor System #AL74000EZ is only the compressor kit. We sell them separately since we get a lot of people only wanting to add one or the other. For an air bag kit, I really like the Firestone…

Great news Ross! Thank you for the photo. The clamps on your Yakima FrontLoader part #Y02103 will absolutely work with your Thule WingBar crossbars! That rack is designed to fit a wide range of bar shapes, including aero-style bars like the WingBars,…

There are a number of differences between the Firestone Ride-Rite Air Helper Springs #F2445 and Air Lift LoadLifter 5000 Ultimate Air Helper Springs #AL88299, starting with fit. While the Air Lift will fit all models of the 2018 Toyota Tundra, the…

The Timbren Spacer Kit item #T68MR has two 1/2" Spacers and two 1" Spacers which all have a 3/8" bolt hole opening. Also included are 3 pairs of different length bolts to ensure you have the correct length.

I attached a picture that shows how the Timbren #TGMRTT35D that you referenced gets assembled. The spacer #TA25722-90P00 you referenced would go between the numbers 2 and 3 and you'd be set. See attached picture. You will need to provide a longer…

I have attached a drawing from the installation instructions for the rail kit part #C16430-204 you can check out. As you can see in the attached drawing I noted the carriage bolts and where they are located on the rails when installing. Please note…

The Lomax Hard Tonneau Cover part #AB1020099 for the 2020 GMC Sierra 2500 6-3/4 ft bed is not affected by the MultiPro Tailgate and is still a perfect fit. The Lomax Cover is a great option for the Sierra because of it's nice low profile aluminum…
