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. 🛠
