REVIEWS

Put these Yukon 4.56 gears in my ’17 Jeep JK and the difference is huge. Running 35s now feels effortless — tons of low‑end torque and no gear noise at all.

Installed the Yukon Dana 30 4.56 set on my JK for off‑roading in Moab. The crawl ratio is perfect now, and the gears are quiet even on the highway. Couldn’t ask for better quality.
