The Best Rear Differentials for Honda AWD Swaps: What Works & What’s New

Intro:

Honda AWD builds have exploded in popularity, but choosing the right rear diff is critical. Not all differentials work well with Honda AWD setups—some are too weak, some don’t match gearing well, and others require heavy modification.

With the recent discovery of the Jaguar rear differential as a viable option, AWD Honda enthusiasts now have more choices than ever. This guide breaks down the best rear diff options, their pros/cons, and which one is right for your build.

1. What Makes a Good Rear Diff for a Honda AWD Swap?

  • Must closely match the front transmission’s final drive to avoid drivetrain binding.
  • Must be strong enough to handle high power levels if applicable.
  • Should have LSD options for better traction.
  • Should be easy to source and not require excessive modification.

2. Popular Rear Differential Options for Honda AWD Swaps

1. Honda CR-V / Element Rear Differential (Stock Honda Solution)

✅ OEM Honda fitment, easiest swap
✅ Works with CR-V drivetrain setups
❌ Weak for high horsepower (around 500-600hp max)

❌ Viscous coupling built into diff housing (must be blocked/pinned or upgraded)
❌ No factory LSD, open diff from Honda

2. Wagovan (RT4WD) Rear Differential (The Best, But Rare & Expensive)

✅ Strongest OEM Honda rear diff for AWD builds
✅ Factory design meant for early AWD Hondas
✅ Direct swap into EF/RT4WD chassis
❌ Getting very rare and expensive—hard to source

❌ Aftermarket options exist, but are very expensive

3. ’02-’08 Jaguar X-Type Rear Differential (New Hot Option for Honda AWD Builds)

✅ Newer alternative that’s been recently discovered
✅ Stronger than Honda CR-V/Element diff
✅ Close gear ratios to Honda AWD setups

❌ Needs a custom rear cover to mount in a typical AWD Honda setup
❌ New to the Honda world so real world data is scarce at the time of writing

3. Which Rear Diff is Right for Your Honda AWD Build?

  • For simple bolt-in AWD swaps: CR-V/Element rear diff (best for daily-driven or mild setups).
  • For the ultimate OEM solution (if you can find one): Wagovan RT4WD diff (best factory option but rare).
  • For those wanting the latest & greatest: Jaguar rear diff is a good option..

4. Things to Consider When Choosing a Rear Diff

  • Final Drive Ratio – Must match the front to avoid drivetrain binding.
  • LSD Options vs. Open Diff – Limited-slip improves traction and power delivery.
  • Availability & Cost – Some diffs are easier to find and cheaper to maintain.

Conclusion:

AWD Honda conversions have more diff options than ever, and with the recent discovery of Jaguar rear diffs, there’s a promising new option in the mix.

The best diff depends on your power goals, budget, and fabrication skills. If you want bolt-in ease, go Honda CR-V/Element. If you want strength, Jaguar is the way to go. If you can find one, the Wagovan RT4WD diff is the best OEM solution but is rare and pricey.
