Sorry, shock question-again

My chassis is an 06 built MM with Tuthill IFS w/21K miles. When I hit expansion strips that have a height diff of 1 inch or more I get a loud bang (sound) and a pretty good jolt. To me at least they ride hard. If this is the price to pay for better handling then so be it. BUT, if changing out the stock front shock's would help I'd pay the cash.

Does anyone have experience with my chassis and shock change, positives/negatives etc. I had a gas coach previously W-22 and went from Monroe to Koni and it made a world of difference.

Thanks!

I have a Mountaim Master chassis with the same set up. I changed my shocks at about 25K miles to Koni and noticed a world of difference when hitting those expansion joints and rough roads. I changed front, rear and tag...not inexpensive, but I was afraid the cabinets were going to fall off the wall with the Bilsteins.
If you check this forum from prior years you will find a host of comments regarding Koni's and Spartan Chassis. Spartan reimbursed me for the fronts after I sent them a letter with my invoice and copies of items posted on the forum stating that Spartan had changed out the shocks for other consumers at the factory. That was a while back as I now have 45K miles on the coach.

Ronnie,

Thanks for the insight and first hand experience. I was only thinking of changing the fronts, but now? So I guess you have the FSD on the rear & the red's front? Did you leave the shocks at factory setting or did you adjust the fronts? Also, is it true you need some sort of plate or is it a simple swap?

Mine was a direct swap...I believe they left them at the factory setting. I provided them the weight info for each position.

Ronnie,

Thank you for checking back on this post so quick. I'm going to order the front's today. I really appreciate your insight and am looking forward to an improved ride on an otherwise fine coach.

Double check the part number you order. I don't have my records here at the house. I know I posted at one time the P/N's. I'll see if I can find the info.

I think the P/N is 88051008 or 1009 these are not self adjusting...they heve 3 settings and mine is set on stiffest.

Ronnie,

Thanks for looking out for me! I did go directly to Koni and was able to match the front shocks, so I should be fine. If I like the front's as much as I did with my last coach I'll likely replace all. My previous coach had a solid axle so I'll have to learn the new red's. Actually I'm really looking forward to the change. Much appreciated!

Wardy

Just to follow up... I replaced the stock Bilst. with the Red Koni, and yes, it (2007 MM) ride's much better. Less road noise, less harsh expansion strips etc. The only downside is that I get a little more porpoising. Maybe I should just turn the Koni's a bit bit to increase the resistance.Regardless the ride is more settled, less effort etc. I just wish the Koni's didn't say "made in China"....
