Wheel spacer questions

Looking at the 1.5" spider trax spacers. Looked at previous threads on spacers but couldn't find anything stating if they are safe at freeway speeds? Say 65mph - 80mph? Or are they just recommended for offroading?

I know a lot of shops here won't touch vehicles w spacers. (I'll just rotate my tires as needed myself.) Good thing is, I only put 3,000 miles on the truck over a 6 month time span mostly in town driving but sometimes at highway speeds.

Should I check the spacers every month?

 

When you install, use the red locktite on the HUB studs then torque to spec. Torque lug nuts on spacer studs to spec, check after (I think it was 20 miles). Basically just follow the directions. If you want to check every month, go ahead.
Hub centric SpiderTrax are fine for highway use. However, DO NOT USE CHEAPO LUG CENTRIC SPACERS.

 

Make sure you get hub centric. In pa anything over .5" is not legal for inspection but nothing is really ever said.

 

Spidertrax or G2 spacers should be fine.

 

You'll want to change front wheel studs out with rear wheel studs. They're a little longer and allow you to get a full nuts thread. Thats they way 04 was. I'm not running spidertracs but something similar. 1.5 fronts and 1.25 rears.
