In looking under the Excursion I noticed the driver side bump stop is gone...I replaced them several years ago so it's time again. I ordered some close to these that said fit for our 2000 Excursion 2wd, and seem to recall using the same last time. They are 3.75" long and wondering if they are too long...also not a fan of the design of these, though original, with a single center stud mount which could easily be pushed sideways when in contact with the axle. I couldn't find alot of information here on the 2wd trucks, and even the online parts stores only have them for the 4wd trucks.

 

I used these for my 2wd excursion but they're a bit more. And my passenger side is also at an angle for what I'm sure is due to the concern you mentioned. But sharing in case this link or part number takes you to dimensions you find useful.

I'm thinking a block style might be the answer, but still looking for the correct height they should be...

 

Bump stop height isn't the only specification to worry about.

Bump stop durometer, or hardness / compressibility is another factor to consider.

Especially in the Excursion, which was originally fitted with springs that were more supple than pickup and chassis cab counter parts.

Excursions always had fancier, longer, and softer (lower durometer) bump stops.

GM bump stops in the similar sized Suburban are also a calibrated component of the front suspension system. Even though GM uses torsion bar springs instead of leaves or coils, the bump stop that the lower control arm contacts in jounce is actually the second stage of the "two stage" suspension. The Suburban was designed to "ride on the bump stops" if you will. The bump stop is soft enough so that the control arm "hitting" the bump stop isn't felt, and yet once that contact is made, the compression of the bump stop is part of the suspension.

That is another reason why these types of bump stops wear out so often, while the bump stops in my F-550 are 25 years old, and unfettered, as if new. The heavier trucks are not relying on the bump stops as a second stage of suspension. They are truly only bump stops, to prevent the axle from over traveling upward at full jounce.

On any vehicle, regardless of brand, if the bump stops are yellow, and corrugated or graduated, with an accordion like appearance, and are made of a more porous or spongy like elastomeric material, and are larger overall, wider in cross-section and taller in height... then those types of bump stops are likely calibrated to be part of the suspension system, and are expected to be be engaged more frequently than the small black, hard, solid rubber found in older or simpler trucks.
