why i asked..........if you go with a 7.60 5 rib or cutting tire on the front it should measure 28" tall depending on manufacturer. if you run 28 or 30" in the rear then you will have a balance issue. when i say balance i mean equal ground clearence front to back. now you really prob want the front to sit 2" higher than the rear w/o passengers. the tube you have welded across the lower frame behind the seats that you rear susp and engine cradle will weld to might need to be changed. i put a 35* bend on the ends of this tube to drop it 3" down. the reason for this is where the lower a-arm mounts to the front susp cradle is at the bottom and the spindle stub is located at the bottom of the spindle upright so the center is low. even if you could mount your rear links or lower a-arm in the rear at the same point , your wheel bearing or hub center will prob wind up centered on the carrier, so you already have lost ground clearence compared to front. now my bet is that loss with a 30" tire will amount to prob 2" to 4" ( depending on angle of rear cradle) and depending on where you mount your jeffco you might not be able to mount the lower rod/a-arm tabs as low as the front cradle so another 1" to 2" ground clearence loss too. this is why i drop that tube down the 3" and then brace it to the frame accordingly. and i do mean brace it! not saying you need to change it but you might want to consider it now rather than later, i know you were baseing your build off pic but you can't see all in a pic.the fram looks good from the pics but the front cradle looks real nice btw
I think the rear center bracing is more needed w/a-arms than link style. The forces are just placed at diff spots on frame. I know on my A-arm I had some serious frame flex problems first time out at dunes. DS did a great job supervising me while I welded tubes at dunes. Then I added more tubes when I returned home to carry the forces thru the bottom of the chassis. PS. by supervising I mean he sat in a chair w/cold beer and watched.
I think I am not exactly following here where is the 35* bend, on the rear to lower the rear lower link mounts? The connection points for the rear links will be in the same plane as the connection points for the front lower arm. Same is true for the upper mounts as well. I am thinking I would be looking for the front to be 1" higher in the front I like to keep the car basically neutral front to rear so it doesn't push though the corners even though I will have cutting brakes.The 30" tire is the road tire for around the ranch. I will be setting the suspension with 1100 paddles.
