hi i bought a suzuki sierra 1991 model (1.3l) and it has 31 inch mud tyres on it.
i am looking to get it to go alot slower for some offroad work as low range is a bit too fast sometimes and have been told that putting a 1.0L transfer case is a good way to achieve this. im basically just looking for some opinions and advice on this modification. i have the transfer case and also front and rear diffs which i was also planning to put in to lower the gearing. how would this affect my topspeed as well? ill probly have a ton more questions hopefully this will help some people out.
oh yeah this is also largely because i dont want to destroy my clutch as well.

Hey mate.
Just go straight for 4.9 or 6.5 transfer gears and leave the diffs alone. Its a tried and true solution.
