Comments about Detroit LockerGM 10.5in. 14 Bolt Automatic Locker:

I have a Chev 77 K30 3plus hooked to a 400hp 396 BB. In 4Hi the truck was more or less useless. Against the advise of many "pros" I installed this into my 14 bolt rear diff. Was done in about 2 hrs including beer breaks. Haven't looked back since. Places I go in 2by will blow your mind. Have had it for 3 years now. Keep inspecting unit for wear or chunks, still looks brand new. No visible wear. Hu
