Eibach Rear Springs and Collars

[iwashere1st]

Hello All

So with the new riding season coming upon me (still cold here in western Canada) Ive decided to change out the godawful spring on my rear shock. Ive noticed a lot of people saying that the Racetech springs where in fact Eibach, which I can understand.

What worries me is that the Eibach doesn't list a collar for the shock, while the racetech recommend the collar. Are these in fact the same spring then? Or are people just running them without the collars? If so, any issues, or am i just borrowing trouble?

As i understand it, the sizing is 7'' x 2.25'' x (in my case) 600 or 0700.225.0600 using Eibachs system, correct?

I bought the spring from another website, and then bought the collars from Racetech. Eibach springs are half the price of RT's. I spent a total of $78US for my spring/collars.

You are correct on the sizing.

I got my spring through Racetech as I wanted it painted blue (saved me 2 trips to the powder coading shop). I believe the spring size for the 06-08 and the +09 bikes are different size, so you will need to be more specific to which shock you have on your bike. But you will need the collars so that you can have your shock set-up correctly with enough room for adjustment.

Checking the Racetech page, it lists both the 06-08 and the 09+ as a SRSP 5818, so I think they are the same spring. Both seem to take the SPSC B5855 collar too.

Thanks for the info guys! Gonna go ahead and order the parts!

I have the Eibach spring in the rear, 7" in length is little short, I believe stock is 7 1/2", but it works. I've already max out on preload, so I'm planning to get a heavier spring, and longer this time, like 8"

How much to you weight? Im 155, and about 170 ish with gear on, so im hoping you dont say the same XD

I'm about 160 with gear. I ride very aggressively and Dave Moss told me to get a 525lb spring. It feels wonderful now. I would suggest the same for you.

Yup if you go with Racetech Eibach makes there springs for them. Check on here I did a post on swapping springs

Just though id put an update out on this.

Got the spring and collars. Fit perfect. This was (after my stomp grip tank pads) the best mod for the stock 675, hands down. It feels like a motorcycle now, not a over sprung two by four. Massive amounts more feed back, and sexy red to boot. If you sitting on the fence, get this, you will NOT regret it!

Great info, guys! I'm about 135 without gear. I ordered the spring (525 lb/in) from Performance Spring, and the collars from Race tech...fingers crossed I'll have them this weekend to install.
