Anyone got the exact gear ratios for a Defender 110? Specially for the LT77 or R380 gearbox. I'm trying to plan a build and want to match tyre size properly. 🔧
Good question machan 👊
Here's a basic breakdown (for the common LT77 or R380 gearboxes):
R380 Gearbox Ratios (Defender 110):
- 1st: 3.321
- 2nd: 2.083
- 3rd: 1.396
- 4th: 1.00
- 5th: 0.77
- Reverse: 3.243
Transfer Box (LT230):
- High Range: 1.41
- Low Range: 3.32
These can change depending on model/year – but this is what most 110s in Sri Lanka use. If you're upsizing tyres or changing diffs, best to re-check ratios for better torque balance. 🛠
