World American WAKN48001 Manual Adjuster Review

When I tried this automotive manual adjuster it was a huge disappointment. The design was shoddy and the materials subpar.I didn't see any noticeable improvement in performance, and it stopped working after minimal use. The only upside is that it was easy to install, but that's not enough to make up for the overall poor quality of this product. Save yourself the hassle and find a better manual adjuster..

good quality stitching and fast shipping but spline size and camshaft diameter not listed. They are not suitable for my application.
