I recently picked up a ‘73 CJ5. Has the stock Dana 30 front (open) and 44 rear (worn out trac loc) with 3.73 gears. 304, t15, Dana 20. 33” tires. Hoping to use it for running on trails in the woods, in the sand dunes, could see some snow, and some cruising on pavement. Not a daily driver, but will see some limited street driving. Considering what differentials may serve me best? I’ve used the spicer powr lok in the front Dana 44 of an old IH Scout II I had years ago and liked it. I’ve had a Detroit locker in a 9” rear for years in a street/strip muscle car, so I’m familiar with how it works with the noise and clunking when engaging and disengaging/cornering manners. I see a couple companies make a new production Power lock (Nitro for example); how do these compare to the old spicer units like I had prior? Are they good quality and robust? Was considering a power lok or truetrack in the front, and a Detroit locker or powr lok in the rear. Also may consider e lockers, which would give a lot of flexibility, but I like the simplicity of the other options. Thinking I may swap in some lower R&P gears, say 4.27, but wondering if I would I be better of keeping the 3:73 gears and going with the terraalow gear kit in the transfer case? I have a Ford T18 I plan to swap in, which would help for slow speed work on trails. I’ve heard some caution against the Detroit in the rear of a short wheelbase CJ, especially in ice or snow. Thoughts of those who have more experience with the CJs? This is my first. Thanks in advance for sharing your experience.
