Review on KYB 565104 MonoMax Gas Shock by Paul Hyde

I replaced all 4 shocks with a 2001 gmc 2500 hd 4x4. This made my truck turn much better than expected. The truck is much better on the road. The ride isn't smooth but not terrible, it's 2500hd and it'll never have a drive. The question is how long do they last? All the instructions are in Mexican, but how hard is it to install the shocks? How they behave off-road remains to be seen, it can't get any worse than 18-year-old factory dampers with a mileage of 330,000 km. Tip, if you feel like adjusting the torsion bars, just ride about 1 lap, after that the ride gets tough. I adjusted mine because after 18 years and 330,000 miles the front end is sagging a bit.
