When to Keep the Dana 35 vs Swap

The decision tree for keeping vs swapping your Dana 35:

KEEP THE D35 IF:

• You're running 30" or 31" tires.
• You drive mostly on pavement.
• You don't have a rear locker (or won't).
• You don't do aggressive trail work.
• You have a daily driver that occasionally sees fire roads.
• Cost is a strict constraint and you can't swing an axle swap.

SWAP IF:

• You're going to 33" tires or larger.
• You're installing a rear locker.
• You do regular moderate-to-hard trail work.
• You've already broken a shaft.
• You want disc brakes (the D35 is drum only; the 8.8 has discs).
• You want to run 4.56 or 4.88 gears (the D35 carrier and ring are small; bigger ratios put more stress on small gears).

The cheapest swap is the Ford 8.8 Explorer (~$200-400 from salvage + $400-800 in install parts). The 8.25 swap is similar in cost from a salvage XJ. Both are massive upgrades over the D35 for the price.

Builders who try to make the D35 work with chromoly shafts, c-clip eliminators, and a locker typically spend $1500-2000 total and still have a D35. For the same money, an 8.8 Explorer with disc brakes, ARB locker, and 4.10 gears can be assembled.

NAXJA's frequent advice: "the strongest D35 is the one that's not in your truck."
