  • Beefier auto adjusters. Nicely packed
They work perfectly fine. I've already ordered another set of four for next year's overhaul. This worked on my Dexter 8k axles. Actually, I found the self adjusters to be a bit more beefy than those Dexter brake assemblies. This is the very reason I had to replace the assemblies in the first place. The adjuster just wore out, the teeth on the adjuster...this was the first thing I noticed when I opened the box "dang, those adjusters are definitely more heavy duty" I put 15,000 miles on them BEFORE I left this review. If you remove the hubs periodically and lubricate the adjusters and contact points, they will last a long long time. ... show more

  • Well satisfied.
Items arrived promptly without damage, were well packaged and were as advertised. After removal of the old brake assemblies, I installed the new ones. Fitment was perfect and these were an exact replacement for the OEM parts. All in all, very well made item at a super price.
