iShock +3.5 installed

I just finished up the iShock midtravel install, and need some help. They reworked (re-valve, re-shock) the sport shocks I had. I think the front is set up too soft, but I need opinions from others with mid or long travel setups.

The front sits at about 10 1/2", I can push on the front bumper, and it doesnt rebound very much. It also looks like a have a ton of front end camber. If I lift hard on the front, it sits higher, and the camber pretty much goes away, but another push and back to original settings.

The stock setup wasnt like this, it was MUCH stiffer, and would pop back when pushed.

Should I just pump in a bunch of preload? Add a few clicks of compression? Any help is appreciated.

i would adjust your pre-load 1st who re-valved I-shock?? i would not think you need diffrent springs, you may have changed the shock angle some but not the weight my $.02 but may be wrong
btw congrat on the new kit sucka.

The only adjustment that effects the ride height or sag is the spring preload, compression & rebound adjustments cant really be made accurately by just pushing up & down on the bumper.
The best way to set it up to your own liking from scratch is to first get the ride height set with the spring preload. Trying to adjust the compression & rebound with the wrong preload setting is a total clusterfuck so it's important to take your time and get it right.
After the shock preload is set you can then move onto the compression & rebound if you have them both or just one. I think it's best to set each setting in the middle of it's adjustment range (ex. if there are 12 settings I would start at 6) then adjust up or down as needed until it's to your liking. Adjust each setting separately and be aware that small adjustments will make big changes in the action on the shock.
iShock should have some recommended settings for all of the front end adjustments, if not I would use the stock settings and improvise as needed.

Good luck with the mid-travel kit, I have been wanting one for years now. But just the shocks alone are a big improvement.

Happy trails,
Curley

I think that their flight from and hatred of technology is self-defeating. The Buddha rests quite as comfortably in the circuits of a digital computer or the gears of a cycle transmission as he does at the top of a mountain or in the petals of a flower. To think otherwise is to demean the Buddha--which is to demean oneself.

I agree, I would start with finding out what weight springs you have for the front.

I take mine to a good shop I trust, have them set it up to what they think is the best setting. then i go drive it and make small adjustments. I like to start soft and stiffen it up based on how hard i bottom out. the woops seem to work themselfs out. i only bottom on transitions and jumps for the most part.

Fronts are 200, rears are 475. On a 2 seater.

If I jack the front preload, it will be halfway down the threads, if not more to get it where it should be. I think I need to make a call and bump up the front spring, and then work on the preload.

Thanks for the PM Rick, Ill keep everyone posted on the call I make tomorrow to the tech department.

Without the shocks on, does the suspension cycle up and down freely???

How much preload is in the springs now? 1" or??

Also I would adjust the toe at about 11 off the ground (ride height) it looks like it is toe'd out alot.

Rog,

It is still toed out, it calls for 1/4" toe in, but I havent finalized it yet. I know I need to bring it in a bunch. I figured I should fix the sag hight problem first.

Suspension moves pretty free for the most part, and preload is about 3 or 4 threads down from the top, I dont think its even an inch.
