I could use some help deciding on what locker for the front diff. It will be Dana 60 from Boyce Equipment. Will be running 39 Boggers for wheeling in Western OR and WA. Do mostly trail riding which includes mud, rocks and hill climbs. Boyce has the Lock-Rite for 469, Power Lock and Detroit Soft Locker for 595, Trac Lock for 385. ARB with compressor would be 1003. What has everyone's experience been with the above? Is the ARB worth the extra money. I am leaning towards the ARB or the Trac-Lock. Please do not comment on my decision to go with Boyce.
