I'm trying to sell some old jeep and Scout parts that are stored in a barn. The property is likely to be sold soon and the parts are likely to be scrapped. The owner died several years ago and his widow, a relative of a freind, could use the money just to get by. I'm not making anything on this, but am trying to help the hobby, by preventing this stuff from being scrapped, and the lady, who could use some money to pay medical expenses. All prices are negotiable but I will not ship. Pick up is in Waukesha, WI. I have this stuff listed on several other jeep sites but found this forum while looking for Scout forums. Some of this stuff might be Jeep stuff too, but the wheels would fit both. $100 for all the Scout stuff. Wheels are $15 each, you deal with the tires, they've been out in the sun for over twenty years. I don't know how many pictures are allowed in one posting so I'll move to another.
I’m new to the forum but have already spent a little bit of time reading earlier articles and posts (many of them very informative). My friend and I were having a discussion on gear ratios and bigger (35”) tires, specifically for a 2015 6.7l Cummins Ram 3500 (single rear wheel) with the Aisin transmission (stock gearing of 3.42). Over the course of the discussion we had several unanswered questions about re-gearing for that truck and for bigger tires in general: Why is a numerically larger gear ratio (like 4.10) referred to as “lower” gearing while a numerically smaller ratio (like 3.42) is referred to as “higher” gearing? It seems counter intuitive. I understand that the higher ratio has more gears on the ring gear and less on the pinion, which allows for better towing and slow-speed crawling performance. Conversely, I understand that a lower ratio has less gearing so to speak but is better suited to highway efficiency. Where do the “lower” and “higher” aspects come in? Can re-gearing to a numerically higher gear ratio help offset some of the mpg losses normally associated with bigger tire sizes? I understand that some amount of efficiency degradation is unavoidable when switching to bigger tires. But I’ve also heard that re-gearing can help put the transmission back into its optimal RPM band and also helps to reduce drivetrain strain caused by bigger tires. Is that correct? I only ask because I've seen a lot of Ram HD owners complain about significant mpg losses when making even a mild transition from stock tire sizes to 35's. What is an accurate way to determine the ideal gear ratio for a given tire size? I’ve seen an equation mentioned in several forums and youtube videos: Ideal Gearing = (New tire size * stock gearing)/(old tire size). Going with that equation (assuming stock tire size of 33”), the ideal gear ratio for 35” tires seems to be ~ 3.63. The closest conventional gear ratio is 3.73. Would that be ideal for a multiple use (offroading, towing, highway cruising) diesel-equipped Ram 3500 wearing 35” tires? What RPM band should we be aiming for with this new 6.7l Cummins? I realize that much of this topic was discussed in an earlier post by Moses Ludel back in 2013 (5.9l Gearing Article). His article was focused on a Ram with the 5.9L Cummins and the 48RE transmission. The newer Rams’ stock gearing and engine outputs have changed a bit from those earlier powertrain setup’s, so I’m wondering if his scenario is directly applicable to what my friend and I are dealing with.
