Macktruckman Posted February 22 Share Posted February 22 (edited) Hi all. Can anyone tell me what rears these are? I hope for full lockers but I don’t think they are? Theres no springs just a walking beam. I can see its a 5.73 ratio. This is an RD690S that might be available to me for a parts truck. Its a 1988 or 89. Has a 4 valve EM6 I might use to replace my 2 valve. Possibly. Has what I believe to be a T2080 that I probably won’t use for anything. Its an old mixer truck since new. Thank you in advance Josh Edited February 22 by Macktruckman Quote Link to comment Share on other sites More sharing options...

terry Posted February 22 Share Posted February 22 The 2080 series trans. Has to be used with the deeper rear ratios, it has a real wide O.D. In top gear. Terry 1 Quote Link to comment Share on other sites More sharing options...
Macktruckman Posted February 22 Author Share Posted February 22 I gotcha terry. I probably won’t have use for the transmission personally. I’m curious about what weight rating the rears are and if they have differential locks or if lockers can be added. The rears look a whole lot bigger than my 38 camelbacks. A lot. Lol. josh Quote Link to comment Share on other sites More sharing options...
