Bilstiens! I've had several KYB struts/shocks that either leaked after 20-30K miles or didn't control the bounce right out of the box as well as shocks/struts with 120K on them.
I think Monroe has gone down hill big time and prefer not to buy their stuff either, for the same reason as above.
I had 1 set of Rancho's with the adjustable knob on my 96 2500. The knob seized and wouldn't turn (hadn't adjusted them in 2 years). They were about 9 years old. Rancho wouldn't warranty them. Will never buy another set of their stuff, just for that. I had the original papers saying lifetime warranty - and they were still being sold with a lifetime warranty.
