Well I decided that I would try to remove some of the bounce in the center of my frame by axles so went to harbor freight and bought 2 -5000lb jacks and built the stabilizing bars to connect to them total cost 140.00
Yeah i sort of looked at what they had online and thought i could build them cheaper and stronger.... i went to my local metal supermarket and has them cut all the pieces and punch all the holes for me .... i used 1 inch hot rolled solid stock for the inner tube and 1 1/4 true tube with .090 wall for the outer tube... cost me right at 64 for the work they did and i welded them together and painted them
Oh and I did get to try the extra stabilizers this week and what a difference .... I used the left one to bring the side up about 1/2 inch to level and then ran the other stabilizers down ... it felt very solid with no bounce in the center like it had before
