Topic: R452 Overdrive gear set

[GrandKing]

I have read the posts about running a R452 5th gear set in a R150/151f trans to get a .69 overdrive ratio.  I got excited when I heard about this option, however that elation was quickly deflated when I found out about the availability of the R452 transmission.

My question is this; Why cant the gears be made new in the US (or perhaps a willing manufacturer), and sold as an upgrade for the R150/151's

I think with gas prices being high many would welcome a better overdrive. And would make a R150/151 a more viable option for V6 and V8 swaps that don't run
3000+ rpms cruising.

I admit to being selfish and wanting someone else to make it for me, but i have money.

Because people doing a v6 or v8 swap are running 4.10s not 5.29s

That's not an answer.  I have a 4.3L V6 with 4.10s and could use some higher gears I'm turning 2800-3000 around 70-75mph.  I live in an area where the speed limits are 75mph and 80mph I'd like to keep up without blowing my engine or over heating it. 

 Its really a question of "is there money in it".  I would say yes, not only wheelers could use em with 5.29s and such, but stock daily drivers and the "tuner crowd" as well.

I daily drive my rig with 5.29s and a 22re on 35" tires. In 5th gear at 65 mph I'm running 3250 rpms about. I honestly just think a more viable option would be stepping up in tire size or running a numerically lower ring and pinion ratio.

I have 33's or rather 285/75 R16's but I have another truck with 39's already 33s are a good size for the street.  Also its in a Samurai so 35's wont fit well.

What are you running for a tcase? If you have a Sammy case then you could run different gears to change your final drive.

God no, the only things good on a sammy is the body and frame (as long as its properly braced). I used all yota engine and drivetrain then swapped the 4.3 later.

For the record sammy drivetrain is crap, I seen 4 axle shafts snap all at the same time, ripped out t cases, burned clutches, twisted driveshafts, broken flanges, all this behind stock 1.3L's. I even saw a guy who had his intermediate shaft come loose on the freeway and bang up his transmission tunnel (it scared him soo bad he promptly sold his rig).

Just wondering if any of you guys had any luck with this in the end?

Looking in to it currently!
