Default New Product - Koni 5" Ride Height Adjustment Sleeves

In case your threaded sleeves turn on you when you are trying to adjust them....

Or in case your threaded sleeves and spanner nuts are corroded and in need of replacement...

Or in case the 1" of up/down adjustment on the front of your 928 isn't working with your 19" wheels, or your race tires, or your body kit...

We have a new product for you.

I designed and have begun manufacturing a special threaded sleeve that is a heat-shrink over a Koni Red - and it provides up to 5" of adjustment for your 928, front or rear.

Details here: http://www.928m.com/parts/rideheightsleeves.php

Because they are machined to fit Koni's exactly, you heat them up in your household oven to about 450 deg and slide them onto your Koni where they shrink-to-fit. Now they stay put while you turn the spanner nut!

We machine them out of 6061 billet tube, cut them with course threads (better in aluminum), and anodize them so they will not corrode.

Currently offered separately, I will also be offering Koni's pre-fitted with our ride height sleeves too.

No, these do not fit Boge shocks, but if that is what you need, I have already measured them up and I know I can make them on a SO basis. Bilsteins already have the threaded section on the shock, so this is not for Bilsteins, either.

That looks exactly like the last part you needed to make your coilover (hyper) koni kit look exactly like devek's. Nice.

Now, on the front Konis, the idea was to move the shoulder DOWN a bit from its original position for the hypercoil kit.

WOuld you know why carl?

Thanks, Bill. Yes, its a common axiom among machinists and engineers that course threads are stronger in soft metal (aluminum) and fine threads are stronger in dense metal (steel). I cannot figure for the life of me why these were made in soft metal, not anodized against corrosion, and then made with such fine threads. One grain of sand is enough to seize these up.

All I can think of is that the fine threads do not require a thread lock, they will not turn on their own. We inserted a steel thread lock on ours with a rubber bumper against the threads so you do not damage the threads when you lock the screw in place. You can see it in the picture.

Can you address my question carl? About the shoulder height change on the front Konis on some kits?

Great Idea Carl. I ordered your Koni adjustment tool as I saw it on Sunday: THAT's a very cool product that will save me about $650 + labor (Koni quoted me at $140 per shock to modify to externally adjustable, not including shipping)!

Okay. I have. I have it in my garage right now. They, as part of thier kit, suggest that the front (IIRC) shocks shoulder be moved down for some reason. I had this done (and it only took a year), but I am not sure why. My point is that you have made these to work with your coilover kits right?

Your picture on your side has the original adjusters, and I have added my comments to show where this shoulder change goes:





Is this for both front and rear konis?

If I didn't need the change to the body of the hypercoil I would be happy.

Maybe they wanted to drop the coilover mounts so they could fit a rear spring into the front suspension? Again, I am not sure why. If you did that (put a 12" long rear spring in front ) you would also need to modify a lot of other componants to increase their range of motion to get any benefit.

Anyway.... to answer your question.... our threaded sleeve goes on over your front Koni without any mods to your Koni.

No, I think the front spring is still a shorty, 600lb one, and the rear is a longer 400lb.

That makes no sense. Then why move the mount down? Well anyway - our ride height adjusters do not require any change to the Koni.

I don't know carl and can't figure out why. They have been installed on my 78, but will come back off. I can take pictures then maybe if I haven't figured it out by then.

Just got a picture of the ride-height sleeves installed on a pair of Koni's for the 928 Rear.
