No spin lockers

[schISM]

It’s a pretty straightforward swap but you WILL have to trim the face of the front drive axle housing for the locking mechanism to clear(Eaton DS models), just plan for it and even when it looks like it will clear it won’t. You’ll have to replace the axle also, the splines extend farther out to engage the lock ring. There’s a tool you can buy that threads into the air supply for the lock that holds everything together during installation, I made my own out of a brass fitting and bolt. There’s no adverse effects from running lockers to any other components or tires ect...just never, never, never lock them in if a wheel is spinning. Physically press the service brake to ensure all wheels are stopped then hit the switch. I’d never order a new truck without them but I’m not sure I’d go to the trouble of retrofitting unless you off-road quite a bit. Good luck
