You probably want the setup in my beastie. But as blacknight said it's easy to spin the tyres even in the dry!
I have a ZF 4 speed beefed up with a 2000-2500 stall converter and the rock crawlers in the LT230 transfer case. It was setup for cable pulling.
I'm not keen to use the boat engines to move the trailer for the risk of breaking the front mounts on the trailer and also stirring up debris at the ramp which then goes into the intake. Thanks very much for the tip on the Rock Crawler from maxi drive. My idea boat retrieve is one where you just idle up the ramp. Currently I need to rev the engine to prevent a stall which means the tyres initially move quickly thus increasing the chance of slip. Having lower low range means I should be able to drop engine revs, preserve my clutch and reduce the speed of take off, hence decrease the chance of tyre slip. Thus I can see the rock crawlers decreasing trye slip as I don't intend to take off quickly. Thanks for the tip on not deflating tyres, the mechanic had suggested this !
I'll contact maxi drive and see what happens.
As for going for a F250. Not keen on driving one. Poorer build quality than Landrover, very long , and I don't need the highway speeds that often. Now if the new Toyota V8 diesel has a tow capacity of 4.5 ton ..........
R380 is the 5 speed manual and the LT230 is the transfer case. So you have both.Quote:

I'll vouch for that.Quote:

i have the 49% lower gear set from Maxi-drive in my 110 def trayback.
i tow an 8x5 dual axle trailer full of tools, must weigh about 2t
for tight sites that are hilly etc it kicks ass. can reverse IDLE my trailer up a 200mm concrete kerb.
made from the best material for gears and staight cut for greater strenght. all Australian made

sounds good, do you remember where you got it installed and how much it set you back. The website lists only 30 and 40% reduction, but I'll ask about the 49%.
I have the Maxidrive reduction gears. Noisy as but they are great!
For the same sort of money, you could convert it to a ZF auto (fit a big cooler) - will give you much smoother power delivery and no risk of stalling.
I had a ZF auto/LT230 in a Rangie fitted with 4.7 diffs - it pullled like a train.
The maxidrive conversion should set you back about $1600, $1700 or so.
I've now got the 49% version, well worth it.
I've never had trouble on a boat ramp. If wheel spin is an issue, do you engage CDL? I'd have thought that using low range & the CDL, & knocking the CDL out on the move once you're mobile will get anything up any ramp.

Have you got a link to any sites with pics? I could do with a laugh today.Quote:
