Front Shock snubbers
Posted by: 65auto ()

We've installed new gas shocks on the front. There is no provision to use the "snubbers" from the old shocks. Are the snubbers for bottoming out issues?

Do the new shocks have a pin mount at the top? The old snubbers should slide down over it - in place of the washer and small bumper that usually come with shocks. I don't understand what "no provision" means.

It has an upper and lower bushing as all front shocks do. If I could get the snubber off the old shocks, probably would not go over the welded ring for the lower bushing. What exactly is the purpose of the snubber?

It is the bottom out bumper. You need them since it is the only bottoming provision. I had to grind the shock shaft stop a little on the last new pair I installed. If you buy new shocks from Clark's they come with the little mounts. You have to buy the big bumpers separately.

Use a Razor knife / Box cutter

Install on new shock... Shock tower captures them.

Right metal disc/ washer.... after splitting . Pry until the rubber rips.

We took the front shocks off and then used a vise to get the bump stops off the old shocks. They were off in one minute. Put them on the new shocks and re-installed. Thank you everyone for your help.

Same here. Takes some muscle and lubricant to pull them off but they come off.

I hadn't thought much about them, just always put them in LMs. I took apart a 65 suspension today that doesn't have them. The shocks are old as the hills but not original. I did peek up inside to see if they were captured.

I got to wondering what takes their place in EM front suspensions? Maybe something on the top A-arm that limits travel? My mind'e eye pictures a rubber triangle but refuses to go further. I suppose it would be apparent by looking at one but they've got snow on them now!

If a car is lowered a bunch, trim the bottom tip of the bumper off. These are necessary to save other parts of the front suspension from damage.

A lowered suspension has less suspension travel.

Removing a piece of the bumper allows for more suspension travel before the suspension bottoms out.

A bottomed out suspension creates forces that can damage other parts of the suspension.

The stock bumper is probably 2”+ thick. Bumpers with other shocks like Koni are slightly smaller.

The purpose of the bumpers is to provide cushion when bottoming. I don't see how less cushion would protect anything.

The bumpers provide a limit. I have not actually seen a bumper that showed that it had been “hit” in a stock LM suspension.

This not the case in a lowered suspension.

You do not want a suspension to bottom out in any instance.

It can cause you to lose control of the car at high speed.

Don't tell my cars that. I bottom them all the time and often quite hard.
I guess not really at high speed. Maybe 60mph tops in corners.

Really?

Car manufacturers went to great lengths to avoid "bottoming" suspension - as well as "topping".

Of course, they could not control the maintenance (or not) of suspensions as cars went through their life cycles.

Car suspensions should not bottom (or top) out.

Obviously, you have far too many vehicles to properly maintain their suspensions.

Glad you are still alive.

The bumpers are there to prevent damage to the shock internal valving.

"Car manufacturers went to great lengths to avoid "bottoming" suspension - as well as "topping"."

That is totally false. The bumpers would be unnecessary if they were never intended to bottom. The bumpers cushion the bottoming and topping out. How exactly would you properly maintain suspension to prevent bottoming? Several of my cars over the years have had new socks, bushings, ball joints and bumpers but none of that prevented bottoming. The only vehicle I've ever owned that I don't recall bottoming is my class 7 International.
They top out fairly often also. That happens every time a wheel comes off the ground. Granted that doesn't happen nearly as often as bottoming.
