I went back and forth 4.88 and 5.29 I have 2018 Tacoma SR 4 door 4x4 31 in. tires After changing my mind a couple times I went with 4.88s and Harrop E locker, glad I did I'm at 1900 rpm at 60 mph so same as the same truck with 33s and 5.29s. Just broke them in had my oil changed today and everything came out perfectly! I'm from OC I looked around for a while,almost went with J&T gears In HB that guy is rude,angry and did not even know Harrop made a locker for Tacoma he wanted to charge me more than Premier and wanted to put a trutrack limited slip. Anyway I chose this shop because they do so many Tacoma's These guys do Tacoma's all day everyday. Miguel is real good guy that truly cares about what they are doing and there customer service is awesome. Also after they installed my gears they took my truck over to Jr to install the harness for my locker and he did an amazing job, very clean work! I would recommend them to friends family and anybody who wants gears!
