1 JoeH Posted March 5, 2019 Share Posted March 5, 2019 Rears are 44k, that's what S indicates in rd690s. St would be 38k rears, sx would be 55k rears. According to the below website, the 90 in 690 indicates a maxidyne engine? But I didn't know they still made maxidynes in 1999. Maxidynes we're usually 300hp I think. Someone more knowledgeable will probably chime in. The 6 in rd690s indicates a standard highway frame. Should be a double frame, that's what my 95 rd688s has. Watch out for rust separating and cracking the frame flanges, that's a $25,000 dealer replacement job. https://onlineuniversity.bloomfire.com/posts/2387484-mack-trucks-vin-decoder 1 Quote Link to comment https://www.bigmacktrucks.com/topic/55946-help-decodeing-vin-1m2p289c7xm029160-1999rd-specs/#findComment-417307 Share on other sites More sharing options...
