Items Needed to Flat Tow 1999 GMC Sierra

Expert Reply:

Assuming that your Sierra is a 1500 series, the Roadmaster # 199-1 would be the correct base plate for your truck.

You would then need a tow bar whose capacity exceeds the loaded and ready to tow weight of your 1999 Sierra. For best results, you would want to choose a tow bar with the same manufacturer as your base plates. Since the base plate kit you referenced is an XL type base plate, you will need to choose a compatible tow bar. I have provided a link to our selection of tow bars that are compatible with the XL base plates.

Keep in mind that many vehicles will require modifications in order to be flat towed. According to Remco Towing, which is the resource we use to determine if a vehicle is capable of being flat towed, if your Sierra is a 4WD model, it is capable of being flat towed with no modification. 2WD models would require a transmission lube pump to prevent the transmission from being damaged. You will want to confirm this with GM or with your owners manual.

You would then need to wire your vehicle so that the tail lights operate in tandem with the tow vehicle. I will link you to a FAQ article that explains the various alternatives.

If the tow bar you choose does not come with safety cables, you will need some. Roadmaster offers a 6000 lb capacity cable kit, part # RM-645 or an 8000 lb kit, part # RM-649.

Many states require a supplemental braking system on a towed vehicle. The Blue Ox Patriot, part # BRK2012 is very easy to use and to set up.
