Energy Suspension3.9102G Pull Thru Bump Stop for GM

Fit my 1975 Pontiac Ventura upper control arms!

these worked perfectly to replace my original, rotten OE bump stops.the easiest way to install these is to have the upper control arms installed,with the bushings loosened a bit and then insert the (lubricated) bump stop through the underside of the control arm and then pull down on the arm,using leverage to push the bump stop through by pressing it against the frame. pops through the arm super easy. no risk of ripping the bump stop from trying to pull it through the control arm.

See 'Title" above, no further review is needed.

Got what I wanted but it would help to put measurements in the add

Just as good as factory parts.

These polyurethane bump stops are the perfect upgrade and alternative to stock rubber bump stops. They are actually cheaper than reproduction rubber bump stops and should last much longer too! Though polyurethane bushings are sometimes frown down upon for a daily driver due to their tendency to get squeaky over time, polyurethane for bump stop use shouldn't be a concern.As the other review notes, the "does it fit your vehicle" wizard for this product is not complete. If in doubt, go to one of your other popular auto parts suppliers and cross check the part number. I am installing them in a 1981 Firebird Trans Am. Do a quick search, you'll find this part fits a lot of GM cars through the years (70's+). At least my searching shows that this fits 75-81 Firebirds and Camaros.These particular bump stops are a bargain from Amazon. You will pay more anywhere else!Tip: Install these bump stops before you re-install your A-arms. Bump stops are much more difficult to install once you have springs and shocks installed.

Little difficult to install but I got it and works OK

If you can remove the control arm and put it in a vise then this is best but you MUST place these in the freezer for about an hour or two then use bearing grease and ONLY lube the angle on the tab. NOT the straight part. Then use LineMan pliers. with a big flat grip. That's it and it goes WAY SMOOTHER. Almost to good to be true.
