2003 Alpine shocks

Does anyone know the brand of shocks we need for our 2003 36Ft Alpine coach?

Some use the newer Bilstein. Some use Koni and if you want to spend a little more there is RoadKing.I am rolling down the road with a new set of Koni's and the ride is much better than the Bilstein's that were on.Seems that those with the RoadKing's swear by them.

I just had a set of Koni shocks installed on our Alpine. We've only driven a short distance since the installation at the FMCA Convention in Redmond, Oregon. The ride seems great and the body roll we were experiencing is gone.

The original Bilstein gas pressure shocks were worn and the right rear was completely blown. So, it's no wonder that we feel a great improvement.

Photos of the shocks are in my post here.

BTW - the same Koni part numbers are used on all Western RV Peak chassis.

I loved the Koni when I put them on. But after 20k miles they gave out. Replaced under warranty, and good for another 20k. This time I splurged for the Road King, and love them.

Hi Jim

The same for me...my Koni's have around 20000 and seem to be fading. I am not the original purchaser so I don't think I can get them under warranty but I would have thought they would last longer than 20000!!??

We are looking in to matching ours with Monroe's. Has anyone used anything but Koni or Bilstein or Road King? Also, we were able to get the number off of the front ones not the back. Are the Bilstein's the same, front and back? I see that the Koni's have a different number for front or back. We are full timers but put under 10,000 miles per year on it.

Nope--front and back shocks are significantly different it travel length--back are shorter, front are longer......I am sure people have used other shocks--generic length. K, B and RK are the most discussed....like it that Koni are lifetime and will replace with little or no hassle.....

I put the Road Kings on over 30,000 miles ago and I have had no problems.

We drove from Redmond, Oregon, to The Dalles today on 197 before hitting I-84 to Portland. Portions of 197 are choppy with frost heaves in the road. The new Konis were firm, but compliant - I know, that sounds like a wine snob description, but I don't know how else to put it.

I felt like I had excellent control and my DW was happy in the passenger seat - no seasick feeling from side-to-side sway.

We'll have to see how durable they are. Robert Henderson (Henderson's Line-Up) told me Alpines are hard on rear shocks due to the suspension geometry. He liked the Koni shocks because of the large shaft diameter.

Been there, done that... Bilsteins and Konis; don't waste your time and money, just bite the bullet and get the Road Kings -- there simply is no comparison.

Koop, they are probably harder on front shocks.

They are hard on the rear shocks. After I talked to Bob Henderson, I looked into what he told me. The upper rear shock mount has the mounting bolt runner through the shock eye parallel to the frame.

This puts a side thrust on the shaft as the trailing arm swings through it's travel. The upper mount should have been oriented perpendicular to the frame rail.



The front upper shock mounts are also oriented parallel to the frame rail. I don't know what the difference in side loading is, but Henderson told me more often than not, he finds the rears blown on Alpines. That was the case with my coach, the right rear was blown.

I am sure good shocks on the rear make a difference but am not too sure what/how much force a shock can inflict on the movements of a 20,000 lbs axle----??????
