I have these on multiple trucks and they look great. No issues with fitment, very well made and love the scale look. I loved the black set so I got the red to match my other truck.

these look great and fit with no issues, I've read other reviews on some of the other diff covers but decided to give it a try the front installed with no issues. I'm running a spool up front. the rear had a rocking issue but I'm running a locker and found the shift fork was the culprit it just needed to be centered while installing the cover it fits and the locker is still working properly, problem solved thanks A-Main

Definitely nice The fitment was on point. Would definitely recommend

What reviewers say

All three reviewers rate the ARB differential cover 5 out of 5 and report good fitment with no installation problems. Reviewers praise the build quality and the scale look. One reviewer installed covers on multiple trucks, including a red version to match another truck. One verified owner ran a spool up front and a locker in the rear, and reported a rocking issue that was traced to the shift fork rather than the cover; centering the fork during installation resolved it and the locker still worked. No reviewer reported a problem with the cover itself. The reviews are few and brief, and one of them mentions the rear rocking issue only as a fork-related fix.

  • + Good fitment with no installation issues
  • + Well made
  • + Scale look
  • + Available in red and black
  • − Rear rocking issue reported with a locker setup, traced to shift fork alignment
