Lug Nut size?

[sbenhoff]

I have a 2015 38RL and am planning on having it upgraded to disc brakes. My installer has asked whether I have 9/16 or 1/2 studs. Since my rig is in storage, I'm hoping someone on here can tell me what I have. Is there any easy way to determine it?

My last Redwood was a 2016 38RL and I had 9/16" X 18 on mine... Can't imagine any Redwood having 1/2" studs??? BUT I may be wrong.....

9/16th on ours. Even had lug nuts that were lightly stamped 9/16 on them.

9/16 taper seat lug nuts

I kind of figured I had the 9/16th, but I just wanted to verify. Thanks to all of you that replied.

My 38 RL has 9/16 X 18, but had the cheap lug nuts with caps, I would throw them away and get SS SOLID Lug nuts.
