Gen 1 None Progressive Fork Springs.Who Makes them?

Who might make heavier fork springs but are not of progressive design that will not break the bank?

$83.00 or so on eBay is the cheapest I've seen. They are progressive ones.

So I guess my best bet would be to increase the spacer length and use a heavier oil in the forks?


I am not racing off road or anything nutty. I just wish to reduce fork dive during gear changes and stopping.

I'm not a pro on the spring set up but I'm sure your on the right track. Others here will probably chime in soon. Good luck

Racetech (among others) can set you up with straight rate springs to suit your size, but that doesn't improve the valving. Another option is to consider cartridge emulators. These modify the valving and help a lot with brake dive. Racetech sells Gold Valves for that. But they require permanent mods to your fork damper rods. I didn't want to do anything permanent so I ran progressive inc progressive rate springs with 15w oil for about 8 years and they worked better than stock. It's not a bad budget upgrade.

Today there are more options than ever. I saved for awhile and did a major suspension overhaul after wearing out my second shock.

I recently put the Cogent Dynamic Dual Rate springs in and their DDC - Drop In fork valves, with their recommended 5w oil. No modification to the stock fork parts. This fork set-up is a giant leap forward. Handles great on and offroad. I also put the Moab rear shock on, but you can do it in steps and just the fork upgrade is a big step in handling, comfort, and dive control. I have an Eagle Mike fork brace too, and the Galpher 320mm brake upgrade. Can't be happier with the combo.

Suspension is one area that really benefits from investing once and getting the bike configured to you - properly the first time. I recommend you call Rick and crew at Cogent Dynamics and talk to them about your wishes. They have a full range of options and are super easy to work with.

No affiliation, just a happy customer.

+1 all that, except I only trashed one OEM shock and I have a progressive rear shock. Rick and the people at Cogent are the best.

Try the 15W oil and if that doesn't do it for you, bite the bullet.

Cogent Dynamics rocks! Fork springs, race tech emulators, and his shock totally transformed my bike!
