Evening gents,

I realized the rear axle on my 87 K5 Blazer is narrower than the front… has anybody put spacers on the rear wheels? And if so, what size did you have to put to even them up?

It looks goofy as is.

 

Don't have a K5, but I've used spacers on my Blazer and Sonoma to make the front & rear wheel track the same width for 10 years. For the K5 you'll have to find the axle width from wheel mounting surface to wheel mounting surface. The difference front to year will help you pick what size spacers to even it out.

The biggest thing to worry about with spacers is making sure that you properly torque, and then retorque the spacer nuts exactly the same way you're supposed to do when you remove a tire. You put them on and torque them to spec. Then after driving for about 100km you have to remove the tires, retorque the spacer lug nuts, then re-install your tires. This process is only necessary each time you remove the spacers.

Edit to add: For those who don't use the metric system, 100km is around 100 football fields, or 67 aircraft carriers.
