Yes, if they are installed right and if the application can be applied! however their several factors. Spacer thickness, wheel lug hole type (conical seat, ball seat, and shank seat) The easiest ones are as long as you still have some of your hub from your brake rotor or drum that can connect to the wheel and you can get 6 full turns of your lug nut or bolt you are okay. if you can not get 6 full turns and your wheel is a conical seat you can purchase E.T. Lugnuts. but this is just an easy example. Another easy type of spacers is hub-centric spacers mainly for BMW and Mercedes. but as I said there so many factors that only a wheel specialist will know if they can be adequately applied. Now some sites say no but those are the guys that did not know what they were doing the first time and the results showed, Plus if they were not safe H&R would have been out of business a long time ago. below are all of the myths busted.

I Heard Spacers arent Safe True or False?


No, wheel spacers are perfectly safe if installed properly. The most common cause for failures is not due to the actual wheel spacers but install issues. If the wheel, hub, and spacer are stiff enough that it does not flex under pressure, your setup will be perfectly safe.


Wheel Spacers Will Cause My Wheel Studs to Bend


Not true. The load from the wheels is transferred to the axle and hub by means of friction through the clamped joint. You cannot bend a wheel stud. The only way to do so is if the lug nuts are torqued improperly.


When Using Wheel Spacers The Physics of the Wheels Are Disturbed and Not Correct


When you insert a wheel spacer between the hub and wheel nothing in regards to clamping force, the coefficient of friction, stress applied to the studs, flexing, load, or any other physics involved are changed.
