Outer Limits 4x4 Board

I'm fitting MQ diffs to my zook and am wanting to either weld or spool the rear as i can't justify spending the big $$$ on a rear air locker for a vehicle that won't be a daily driver.

I know it can be welded but would like to know if spools or mini spools are available.

Thank you

Spool will cost near same as a locker if available, save you pennies and get one later after youve driven a round for a while. All you might need to do is lower tyre pressure.

Why dont you get a rear diff with a limo set up in it, its doing me just fine in my MQ.

Do they even have H233B spools? Never heard of 'em...
