Very good package

Decided to build a shop truck with a gasser stance and feel, I purchased this kit and installed it in about 4 hours. It's a very good kit the only thing you have to be sure is to order your caliper adapters or your going to be left unable to finish. But all and all a great kit and will definitely purchase again.

What happened??

Parts missing. Parts un identified. I assembled one of these straight axles from your company in 2008 and that one was much better in quality. I am not even sure if the hubs are on the spindles as far as they should be. Plenty of grinding (as mentioned on the instructions) of the caliper and spindle to get clearance. Not at all impressed. I need to contact your tech support department tomorrow. Jeesh.

Missing parts and probably the worst instructions in the whole industry. Pretty big let down honestly. Good news is the documentation is so bad you don't really know what you are missing either way. If you buy Lego kits and throw the instructions in the trash this is a good fit.

Would Not Recommend

Great kit, nice quality components!

hi I have a rat rod project that's running and driving with the factory IFS setup but i'd like to put a solid front axle kit on it and be able to bag it so it would drop all the way to the ground while parked at shows. its sitting on a 94 S10 frame. would like to get a kit that includes everything I need for the front end setup minus the bags, I'll worry about those at a later time. what would you recommend?
