ARB or their Chinese knock-offs are the only locker options for our 33 spline H233Bs... A shame really, it's a beefy diff that would probably be more than enough for built rigs if parts weren't so expensive and scarce.
You could stay cheap by swapping in a 30 spline H233B third member and axle shafts from a first gen Pathfinder. They had much tougher LSDs than the ever Xterra got (around double the breakaway torque of the 00-01 models, 4x stronger than 02-04) and there's a Lockrite lunchbox locker available for the 30 spline diff. Probably cost a couple hundred at the junkyard for the third and shafts...
Technically you'd lose a bit of strength going from 33 to 30 spline but it would be a marginal loss. Lots of guys beat on those old Pathys hard with big tires and the 30 spline still holds up pretty good by the sounds of it.
It's not really an Xterra anymore...
