Your first upgrade starts here!
Everyone recommends these weighted diff covers for a reason. Bolt right up, looks great, functional, helps COG, and a great price! There’s heavier ones from other places, but ultimately the cost of these were better IMO. I’ll buy these every time from now on! Do it!

Good value for TRX4
Bolted right on my 79 bronco. Adds good weight, and it looks great! The steering arm linkage hits the diff at full lock, I don’t think it’s a problem but I will probably replace the linkage with a bent one to give more room around the diff.

Tight fit but great otherwise
These work as they should and look great but one of them was a super snug fit. It took a lot of wriggling and jiggling to get it on the axel, the second went on like butter. I'm only running it on the front so the second is just spare/backup. All in all I'd say these are a good value, not great but good.
