One set of (4) Centramatic automatic wheel balancers for Jeeps and other vehicles with a 5-on-4.5" or 5-on-5" bolt pattern.
These help automatically balance your wheels when driving faster than about 20mph. Helpful for vehicles with oversized tires. May reduce wheel wobble problems.
Part #300-345.
Depending on your wheel offset/backspacing, you may need spacers to run these.
I ran two of these up front for a couple months, they worked fine. The other two are brand new, never used. They're all from the same box. I eventually fixed the problem I was having and don't need these anymore.
They're $250 and up online for a new set. How 'bout $30?
