Wheel Spacers Safe

I am looking to get 1" spacers for my 900 trail. Reason is I installed the HMF U4 winch bumper and my tires (28x10x14 on HD6 wheels) rub the bumper at full lock. I will eventually add the S+3 conversion later but for now maybe some spacers. I trail ride mainly are the spacers a good choice and would they be safe for my other suspension components?
