Build suggestions

I'm planning on building a stock 88 Samurai up for trails and some rocks. Will be street legal and seeing some street action. Here's what I'm thinking. Susp: stay SUA with mix YJ/CJ and zuki leaf packs front and rear, sawzall the rest to clear BFG MT 32x10.5. Drivetrain: spool rear axle and keep front open. Re gear axles and Tcase (don't know ratios yet). A Kong or sling for the Tcase.

If you are planning on a street and Offroad I would suggest a selectable locker in stead of a spool.

2nd the no spool. I had my rear welded for a year and its just annoying. If selectable out back is too pricey, Id consider lunch box front, open rear

Thanks guy! Any suggestions on the gearing? No desire to drive over 70mph but will need be low enough for crawling. I'm in north Texas, it will see some (Gilmer, Bridgeport) trails and Oklahoma rocks (with 6k winch and strong tow points).

I disagree about the a rear spool. I've used them for the past 18 years on various vehicles. They are very predictable, especially in a sammi. Selectable is best, but the auto lockers pop and bang on dry road and lock up when you're not expecting it on compact snow and ice. Live in the north west and best bang for the buck has been spools for me. Like I said, predictable and I drive my sammi year round. Only bad thing is wear on the tires.

I had a auto locker in mine and it was terrible with popping banging and lane changes. I went to a spool and like it much better.

I DD my Samurai and also use it to get around on my hunting lease. Tire wear is accelerated but I rotate them every 3k miles and I don't have uneven wear.

On the gearing side, you still original carb 1.3?

If so, then I'd suggest the following;

best option, change out axle gears to 4:56 or 4:62's and do a 4.16 or 4.9-1 tcase gear set. But this would be more cost and work.

Second option; keep stock axle gears and go with 6.4 or 6.5 tcase gears only, keeping stock axle gears. Then can upgrade axle gears later if you feel you need more.

If no real motor upgrades in immediate future, save up for a myside carb and a full 2" dia exhaust. will help your motor give you all it can.

I also vote for selectable lockers front and rear. If only 1 locker or only 1 for now then 2 later, put it in the front first. On-road will be much better and offroad will have slight advantage over it in the rear. Its against "normal" thinking, but trust me, its a proven method.


My DD wheeling zuk on 31's; I am running a 1.6 8V motor with a 1.3 fuel injection (so I'm not full 1.6 power), SPOA, stock axle gearing and 4.9 tcase gearing. Lockright in front and air locker in rear. plenty of gearing for slow technical crawling and still can hold 70 going down Colorado highways. If I was to go up a size in tire, I would go up to 4.56 or 4.62 axle gears.
