Hyperco spring possible mod

[evolved4g63]

This winter I'm planning on a full suspension redo. Fork seals, race-tech springs and hopefully a new rear spring with the correct rate for my fat arse.
Instead of doing the ohlins thing for over a grand, I'm looking at the hyperco spring for about 75 bills. And race-tech valving.

Now the question is, what length spring would be best? The hyperco's only come in 7 and 8 inch lengths. O.E. is about 7.5 inches. So what would be the better choice? Thanks.

What did the folks at race tech say?

My guess would be to go with the shorter length spring and just add a 1/2 inch spacer

I have a Hyperco spring rated @1000lbs out back Bcuz Im stretchd out 9" and lowered 2" w/probly the worst undertail for stretched bikes *very large taillight* I needed it to keep from scraping the thing on the rear tire, esp. when my wife rides w/me.

I personally love the Hyperco spring-rode all over N.C. @ Spring Bash and just did 550+ miles at Midwest MnG few weeks ago. I cant remember exactly what length I got, but if you call GPW (Greg) at Hyperbike he knows the specs He's the guy who set up my rear suspension specifically for the longer stretch-you may want something different if you're not a straight-liner like myself

Good luck bro

I haven't talked to them about the spring yet. According to their calculator they don't even carry the spring rate I want.

They're friendly enough. I would give them a call and talk to them about what you're looking for. Their very honest folks with tons os suspension knowledge. You can't go wrong.

I thought the same until I did some searching on their site. they carry(or list) the 800225 Series Eibach Spring as an alternate spring. you will need the spring adapter collar to mount the Eibach spring.

800225 Series Eibach Shock Springs
