2002 Rear bump stop height??

2002 Rear bump stop height??

Postby racermech [OP] » April 17th 2016, 4:48pm

SO my 2002 cargo currently has 1 bums stop that looks like a stack of donuts. We I went to the local pick a part and the only stops I could find on an astro where solid rubber triangle shape things. Physically I believe they will fit on the axle, but my concern is they are about 1" taller then the one that is on the van.

If I leave them tall it will limit the travel, but if I overload the van the limited travel could help as it wont bottom out the shocks. If not I can trim down the bumps by about 1" to match what is currently there assuming that is the stock height and it has not flattened out a bit.

Stock are approximately 4", I wouldn't worry about them limiting travel as they compress quite a bit. If your shocks are bottoming out then your shock length and/or bump stop length isn't correct.

Thanks!! The triangle ones are solid for me,, dont see them being able to move much, but I am also not super worried about that. If I am fully loaded it will be for less then a 5 mile trip and I can deal with a little bit of a rougher ride.

Kinda answered my own question. Looking at other threads the stock donuts look like 3.5" The triangle ones I found look like 4" So the question remains do I trim or leave them as is?

Leave 'em. If your rear end is bottoming on the bump stops more than once in a rare while then you've got other problems. If a half inch difference in bump stop height makes a difference, you've got "other" other problems.

Probably even better practice would be to replace both bump stops with the other style. And even better than that to replace with the ES or other poly.

My 89 had what I assume were the original bump stops. They appeared to have never bumped. There are people here, on the other hand, that say their vans hits the stops when they load up and/or run over fat zombies.

I suppose if you wanted to get exacting about it you could measure the collapsed length of the shock. Set the bump stops so that the axle cannot travel far enough to allow the shocks to bottom.
