Best Answer:Hey Ben, I hope you are doing well. In concern for the right size truck for the deck you are looking for, a 7.75 deck you would want it paired with a 5.0 or 5.25 truck. The 5.0 truck pairs sell with a 7.4-7.75 deck and a 5.25 pairs nicely with a 7.75-8.0 deck, mainly fitting more towards an 8.00. God bless you and I hope you are safe and learn a bunch of cool tricks on your skateboard!!
