I've had them on a '99 Dakota for about 500 miles and they worked decently. I'm giving them 4 stars because they were recommended for a small pickup truck like mine and they definitely aren't. I started to feel bumps after the first 50 miles, but that didn't change for 500 miles. I think that's mostly because I'm in a big pickup truck, but they still have quality shocks for a very low price. I mostly ride on the road and they are the best for the price. UPDATE Those shocks are clearly not for trucks. Mine ran about 1500 miles before it got so bad the engine mounts came loose. Spend your money and choose another brand.
