Used these to fit GMC Jimmy rims on the back of my 2wd GMC Sonoma, definitely wouldn't have been able to use a smaller spacer, and I really like the tight fit of the hubcentric part to the rim and hub both, it's a stronger style and I have loaded the truck up with multiple loads of firewood till it hits bumpstop and driven home and also drive it daily to work and haven't even had to re-tighten any lugs! Make sure to clean and use locktite on the lugnuts holding the spacer to the axel! I learned the the hard way on a Jeep years ago!
