Of course, you can buy all these items separately but they may not be the same models – companies sometimes make a part that’s only available in their kit. Many people like having a specially made kit to either save time or just to have parts that match.
When you piece up all the parts separately, lots of these options are pretty good deals. But, it’s up to you and taking into consideration your vehicle to decide what will work best. One thing ALL these kits leave out is a shovel. Get yourself a shovel, and something to place underneath your tires for leverage. A mat or even a 2×4. These two things will save your behind.
And if you’re looking for straps separately it’s good to know the differences. Tow straps are meant for slow deliberate pulls and snatch straps are made for a quick “yanking” type of pull. If you try to yank out a vehicle with the wrong kind of strap – the tow strap, then you’ve made a big mistake.
You can go to youtube and see dozens of videos of hitches failing, bumpers being ripped off, and general misery. All because someone wasn’t aware of how a strap should be used.
