Hey ya'll. I just replaced all 4 shocks on my 94 Explorer Sport. All but 1 were still original. When I compared the new shock to the old one, I noticed the stock back ones were bigger around and heavier duty like the Rancho shock. The Monroe's felt a little more stiff than the old ones, I'll bet from being worn. The front shocks were another story though. The old shocks were the same diameter, but much harder to push in than the Monroematics. I was reluctant to install them at first, but am glad I did now. The ride is much softer now and many noises I used to hear from the undercaraige have been reduced significantly. I was even considering getting solid urathane engine & tranny mounts before I installed these. If your 1st gen rides alittle too rough for you, I highly recommend installing a lighter duty shock atleast in the front. These aren't 1/2 ton pick-ups with big V-8's so you won't need the same dampening as they do. Hope this helps!
