Diff drops are never needed.
TRD Pro front shocks have 8 bypass zones (5 compression, 3 rebound) and are paired with TRD-tuned springs that provide an additional 1 inch of front lift; rear shocks have 11 bypass zones (7 compression, 4 rebound) and are paired with 2-inch piggyback reservoirs. It’s level. No diff drops added.
The Pro and OR diff, UCA, LCA and CV are the same. Suspension is what’s different.
I’ve heard people say they’re needed and not needed. Can you explain why a diff drop is not needed? Even for a 2-3” lift? How does it not cause stress to other areas of the drive line? What about the CV angle since it has IFS? I’m seriously just trying to understand why. Thanks.
