will these rear springs fit my 550?

i'm looking to replace my rear shocks, they're starting to get a little too springy for me. i don't want to lower, just get something newer and stiffer.

will either of these fit my 550 maxim?

The problem with using harley shocks is that you will have to press out your old bushings and then they (the bushings) might not fit in the new shocks at all and then you have to make your own. The spring rate on the harley shocks will be much higher than your xj too because your xj weighs a lot less than a harley. So if you do get them to fit on the bike you will have a much stiffer ride. Also I have found through trial and error that the valving can be very different from shock to shock I tried a set of shocks last year that would bottom out every time I pulled a hole shot and took forever to expand. You should really see about getting an after market replacement shock for your specific bike the lack of headaches alone would probably be worth the extra money.

 

Exactly.

Fitting shocks intended for a completely different weight (and power-to-weigh ratio) bike can often wind up giving you unexpected results.

If your shocks are getting "springy" then they're probably just worn out. The stock Yamaha (KYB) shocks tend to do that after about 6000 miles.

I highly recommend the Progressive "12" series shocks as a cost-effective replacement with a performance inmprovement (and I do mean improvement) in the bargain.

Do yourself a favor, and just buy a new set of CORRECT shocks for your bike. Not shocks designed for a bike that weighs 150% percent as much.

If Progressives are still out of range, then honestly, check JC Whitney and get a set of imports that are at least correct for your application.

Not Suzuki Savage shocks either; they were even crappier than the Yammies' to begin with.
