The Timbrens Worked out Great. I used them on my 2002 Chevrolet 2500hd. The reason for the timbrens was that I purchased a 9.5 western V plow that weighs close to 1000pds. The ride of the truck was effected when the plow wasn't connected but I removed them in a snap for the Spring and summer months . I will be re-installing for the winter. Great Product! I have 4 jeep cherokee sports with front timbrens and two with rear. Also have ford f-350 with rear. They are the. "Simplest" way to get more carrying capacity out of any vehicle!

Put these on my Chevy 3/4 ton pick up a couple of months ago. Rely easy to install. I have a ranch hand bumper on the front of my truck and they compensated for the extra weight. They also look like they will last a lot longer than the factory bump stops.

These front rubber bushings are a hundred times better than the stock hard foam pieces. Worked just as described with no issues installing them.
