I have had the long travel system on my 4runner for over 8 years now, and it has done well. I loved it for fast travel in the so cal desert where i used to live. Now in the pac nw forest. It does have its weaknesses though. I have managed to grenade the universal joint that replaces the inner cv twice. When it goes, it destroys the slip axle. This usaully ends up costing about 200 dollars to replace. I don't know how much longer Downey is going to keep producing these, and I am not going to buy spares. I plan on sas at the end of this year if i can stay on a budget and collect my parts. Over all, it was a good investment for me. jeff
