if you go that way you will need 2 - 3 inch spacers stacked up or maybe a 3 and a 2 , seen people do that , but I also seen how much added wear it puts on the hub splines to run just 1 2inch spacer and large tires

I think the deep dish rims in the rear make it look good , even with the deep dish rims my bike in the pic has 2 inch spacers to keep the tire off the muffler ,

I have to disagree with Mac on that , seems to me from experience the farther out you get the back of the rim flange away from the end the axle tube the more it wobbles out the splines inside the hub and thins the splines , it is about leverage -------- I got 5/2 rims with a 2 inch spacer so it is pretty much a 7/0 ( or maybe thats called 0/7 ) , with 26x12 Mudzillas it wore the hubs faster than anyone of my other 300's with the 250/350 rear ends with 25's and less aggressive threads

I got a new to me axle and two hubs yesterday for a 86TRX250A , very good condition , to go into my rear end , right now both side hubs are JBWelded in to take up the slack in the splines , that works and will buy time , going to run it till it gets loose again , and if I don't have time to fix it right I will probably just weld the hub to the axle and run it some more

oh , in the pic I threw in a ATC250ES axle ( the one in the rear ) which has worn out hubs and axle splines , so you can see the difference in length that we were talking about on another thread , it is about 2 inches

I agree with Mac on this one. Sounds like the OP is just trying to overall match the stock offset in the rear. So whether you get to that total width by a high offset (stock) rim, or with a spacer and front offset rim, your hub/splines see the weight put on from the same width. Now if you go spacers to go wider than stock, now we're talking added stress.

Sam, delta steels are super durable. I'd get 2.5" spacers for each side of the rear, then get 4 identical rims and tires and then you can rotate front to rear and even out wear throughout their life. I wouldn't worry one bit.

are you speaking from experience ---- have you ever run spacers on anything you own ------ I got 7 bikes running at the moment with spacers on every wheel front and back , 6 of them are 300's with modified rear end conversions , I think I have seen what spacers do

I would agree with your theory the way you put it , that everything should remain the same if you added a spacer to the wrong rim for the bike to achieve the right offset , but that is not what is going to happen here in this case , it will take at least one spacer to get back even and then another to get the right offset as he doesn't have a stock rear end and spacers are needed to clear the muffler , so that is sticking it out farther than originally equipped

350D rear is wider than OEM.......not that it matters the point I'm trying to make remains, you put the same stress on the rear end regardless of whether you use a deeper offset wheel or spacers. Think about an IRS machine, you can run SRA wheels and make it 3" wider per side or run 3" spacers....what is harder on bearings?

I totally agree with you that putting spacers on another offset rim to achieve the same offset as OEM is the same -------- but when you stick it out past stock to clear the muffler , what I have experienced with mine is the inside the hub gets loose from two ways , it appears the hub gets egg shape and the splines of the axle and the hub get thinner then the hub goes farther onto the axle , I am running the same offset rims as stock , the tires are bigger and the extra 2 inches of spacer is putting more leverage on the hub , no doubt sticking it out 2 inches past stock makes a lot of difference , then when you added in the bigger , heavier , more aggressive tires and a "ragging it mentality " it shortens the life expectancy of the hubs and they are getting harder to find for the 250 rear ends --- I know you have to pay to play , so it is what it is
