Trucks are sold in sets of two.
Recommended for deck sizes 8.12"- 8.3
You will notice that there are some areas of overlap on the deck sizing recommendations. There are area’s where more than one size of truck will fit. It really comes down to personal preference, and can also depend on what size wheels you ride. Don’t stress too much about it though. Use these sizes as a guideline, and you’ll be shredding in no time!
