    Front Progressive springs for 78 750

    Hey guys, I was just wondering what is the correct front Progressive Springs part # for a 1978 750?

    Their website says its #11-1108 but that's for a 1978 750E, my bike isn't a 750E but just a stock 750 with wire wheels and single front disc?

    I assume that they will fit considering both bikes have 35mm forks, but just wanted to confirm this with some experts,

    I'm going to replace the fork seals too, should I replace them with OEM seals or is their an equivalent quality aftermarket one?

    Cheers

    You're right in your thinking, the forks are the same so those springs will work for you bike. Buy OEM fork seals, they're not much more and they always seem to seal well. Have a look at your dust boots as well, make sure they are not so cracked that they would allow dirt in there.

        I always use partsoutlaw (aka Suzuki boulevard), when ever you're having things shipped from the US just make sure they use USPS for shipping, any other company will charge your a customs handling fee at the door. For the seals just get your local Suzuki dealer to order you a set, they might be a more $$ but if you ad in the shipping from the states it'll be the same or less, they might even have them in stock. Any US items less than $50 has not customs charge but Fedex, UPS and shipping companys other than USPS will charge you a handling charge, I've had $40 on a $25 dollar part once

          Hey quick question. Why are you putting progressive springs in instead of Sonic springs? just making sure you've thought about the difference

                What's the difference between sonic springs and progressive aside from the price?

                  Sonic are straight rate springs, made and sold by a GSR member.

                    Then I must be mistaken by them not having a set for my bike, what's sonic springs user name? I would rather my money go to a forum member anyday

                      That would be me.
                      We have them for the 750, listed as 750E in the catalog but they do fit your bike.

                        Perfect, Thank you.
                        I was not sure and sent you an e-mail to your company today. I guess I will have to install PVC spacers with the new springs as well?
