84_red_Datsun Posted March 12, 2019 Report Share Posted March 12, 2019 Does anyone know the stock gear ratio for the 1984 Nissan pick up 4x4 Quote Link to comment
datzenmike Posted March 12, 2019 Report Share Posted March 12, 2019 Look under the passenger side hood hinge, down on the inner fender for the engine tag that's riveted there. It's about the size of a credit card and has this information on it. Bottom line where it says TRANS/AXLE....... FS5W71B..... HF38 The 38 is the ratio and stands for 3.889. 35.... 3.545 37.... 3.70 41.... 4.11 1 1 Quote Link to comment
Stoffregen Motorsports Posted March 12, 2019 Report Share Posted March 12, 2019 It's interesting how you can see what the trends are these days by what people are asking on forums. This gear ratio/diff question has come up a lot lately, which leads me to believe that there must be a new interest in 720 4x4s. Maybe I should buy a bunch and get a head of the curve... 3 Quote Link to comment
Charlie69 Posted March 13, 2019 Report Share Posted March 13, 2019 (edited) I believe the stock 84 Z24 4x4 ran a 4.11 Edited March 13, 2019 by Charlie69 Quote Link to comment
datzenmike Posted March 13, 2019 Report Share Posted March 13, 2019 Wow, did not see the 4x4 in the question. Yes 4.11 for the '84 although the very earliest '84 model year ones had a 3.889 listed. These would have build dated in late '83. 20 hours ago, Stoffregen Motorsports said: It's interesting how you can see what the trends are these days by what people are asking on forums.

I too have noticed this trend. 1 Quote Link to comment
