Front shocks

Found a Koni part number for the front shocks, 99B-3209, about $220 each. Are Bilsteins available? Id prefer them.

Also, aside from visual leaks, are these beefy shocks easy to tell when failed?

Yes, that is the correct Koni PN, at least for the 2003 Alpine.


Please post what coach you have.


And, that shock is an excellent shock, tuned for the Alpine suspension (first hand experience).


For this application (certainly there is no ideal shock for all vehicles) why do you think a Bilstein would be better?

We bought the Koni 99s. Big improvement over the 88s. They made a huge difference in ride and we would recommend them.

Other than leaks, a general sense that rig is bouncing over bumps [porpoising] ….otherwise, you have to remove a shock and test for damping in both directions--a worn shock will have little or no resistance....Koni 99s have been a great improvement for me.....

We installed the 99's up front and the difference was HUGE!

I now have a pair of 88's for the rear just need to find a time to get it in for the install as the rear wheels need to come off for those babys!

I installed the 99s 4 years ago, big difference. The fronts are a piece of cake to change, less than an hour taking your time.

The rears, 88s, were a bit of a challenge but I got it done. Big difference in size of the new 99s.

Were you able to change them without removing the wheels?

I also installed the Koni's. What an improvement. Went from from herding a water bed down the road to driving a sports car.

Not sure it can be done without removing the wheels. Heres mine from last weeks rear brake job. I only wish I had bought new bags and shocks too. It would probably only take two hours more to change them out. Oh well, next time. Really, it's not hard to remove the rear wheels, just have good 10t jack stands.

Paul, Yes I did it without taking the wheels off. As I recall I drove up on a ramp to get a little extra room and adjusted a little with the jacks. I wasn't gonna tackle it at first but I took a real hard look at it and said, "why not".

I had to use a couple of different extensions but I got my impact in there and reached the nuts and got things undone. It's pretty cramped and it takes a little effort to get the shocks spread to the right length to match the studs. I reached things from in front of the wheels as I recall. Things went back like they came off. If memory serves it took less than 2 hours and could have been a lot worse. I did it in my driveway.

Crawl under there and really look at it and it may look less challenging than it does with just a quick glance.

As far as projects it wasn't as bad as replacing all of my heater hoses!!

Keep in mind that I was 4 years younger, 4 years stronger and 4 years less wise.

While we're talking projects, I'm looking at the new fancy, hi tech, space age t-stat like you have. My eyes ain't what they used to be and the old one is dim!! With covid I haven't spent enough $$$ these past few months. You said it is a 10 minute install so I'll figure an hour for me.

I also looked at the installation manual and my concern is that it doesn't require a BFH, a crescent wrench, channel locks or an impact. This may be a full half day project!! Oh yeah, I ain't even gonna attempt the wifi bluetooth thing, I already have one "app" that I don't know how to use.

If I think of any more shock hints I'll let ya know!!

Terry

Coach is in my signature

I used to sell shocks, and know the quality of Bilstein. Plus, they are supposed to be 10mm larger.

Sorry, don't see any signature like others.


10 mm larger than 99's with 50 mm pistons?


Yes, very interested. What Bilstein PN do you recommend for the front of the Alpine?
