Major milestone last night! I installed the radiator and got the power steering working then I drove it to the parts store and over to my buddies house. I hit alot of speed bumps at high speed and it still felt ten times better than IFS. I didn't think that it ever hit the bumpstop. I can only imagine how much better it will feel offroad.

gear pattern looks a lil deep. nice job on the sas though, keep up the good work!

ruf is a good choice! its cheap, keeps it low, and they flex good too!

Build looks sweet man. I love how you kept it low.

Also, how do those Daylighters work on the hood? I have mine mounted on the top of the bumper, each one just inside of the headlight on brackets.

Yeah the gear pattern is a little deep but I didn't feel like pressing it back off since it was close and being run on the front.

Also those lights work good. I think they were about 15 dollars. They don't hinder your view like you would think and I also like where they shine when your on the trail. It's like your regular headlights take care of the low stuff and this gets everything else. They are very bright

This is great, i've been looking to lower my sas 4 runner over the last month, this is the tread i've looking for! When i did my sas she went up bout 5". It looked guffy, so out with the 31s and in with the 33s. Like your steering box, i did the same thing you did by rotating the box. Lookin good.

Get a standard drop Pitman Arm and get rid of that flat one and it won't be a problem.

I can't run the box in the factory 3 holes. You can see in the picture where it was close to hitting at ride height. The setup I have right now works great though. The flat pitman arm helped out alot. I plated the frame somemore since these pics were taken. Sounds like a good idea though Wabbit. I could cut those sleeves off and it would prolly work good. I'll look into that.

Yep. Even moved up like it is I'd still make some full plates and plate and sleeve all the holes.

You do RUFs?

Yeah they are old Downey 2 inch lift springs with 2 factory leaves added to them. Need to add one more because the spring rate is a little soft.

Sorry to bring this one back from the dead, but do you have any shots of your final pinion angle?

How is the setup working out for you? Anything you would change?

Thanks, MC

Sorry its taken so long to reply. It's worked out great. I'll have to look for some pics of the pinion angle.We aligned it this past saturday and kinda got an idea how bad off the caster was with the frenched front hangers. It seemed like the caster was about 5 degrees off of where it should be. I could probably just put a shim in it but it has no problems with death wobble associated from a bad caster angle.

Oh yeah it's doing great. It's actually my brother's truck. I just did all the wrenching. He drives it back and forth to work everyday 35 miles each way running 70 and 80 miles an hour on the interstate. We've actually been thinking about a VW 1.9 TDI swap but I just rebuilt the 22RE about 10K miles ago and it will chirp second pretty hard still haha!

Also it rides very good on the trail with the RUF and Chevy's in the back. It flexes like crazy for the fact that the springs that we are running on this thing were basically free. I have the frame plated and ready to notch for the high steer but I have been very busy with school. It barely hits the bump stops on the trail now but I'm hoping after I notch the frame I can raise the bump stops more and lower it down some more. If I do this I will flip the pitman arm upside down and put the tie rod in from the top to give more room for uptravel.
