I have a 1984 Toyota pickup on 39.5. Iroks with 4:10s and a stock tcase and want some options on gearing. I would like to do more crawling and want to know if running dual cases and having 4.7 in one case and running 4:10 would be stronger and crawl well or if I should run a single case with 4.7 and 5.29. Any other options are welcome just looking for some ideas.

 

Take it this is a trailer queen. Dual cases with 4.70. But hang up the idea of road speeds.
