Re: rear sus help
Need more information. What truck are you working on? What is your current drive train set up? How are you planning to use the truck? How much money do you have? Are you installing or someone else?

Re: rear sus help
Not sure what you mean by 65% or 200lbs but I would venture a suggestion the leaf spring set up would fit your needs best for the following reasons.
1. It is a bolt in application with the exception of the spring perches that will need to welded to the axle tube. 2. It is the least expensive option by at least $340 excluding shipping. You can order either TCI set up though from JPL Trucks and get free shipping. I am in the process of reworking the rear suspension on my 54 and have considered both options. That is where my suggestions are based on. However I also found that Posies sells replacement springs that fit the stock mounts, handle up to 400hp, and lower the truck 3 inches excluding an axle flip. They have spring sets for the task forces trucks like yours also. This would be the cheapest solution and would let you use the spring perches you now have. I would replace any shackles and spring bolts with new ones though. Posies also carries those. |

Re: rear sus help
some things to consider
1. coil overs allow easy & cheaper R&R of springs to fine tune your ride comfort level (coil springs come in diff. spring rates) 2. panhard rod does a better job of holding the rear end centered. Only side to side movement will be what the arc is. (longer panhard rod = less arc travel) 3. no more "spring wrap" on acceleration. Bottom line is the 4 link does have advantages, but involves more work to install, & cost..

Re: rear sus help
also are you going low with this or more of a stock look. if your going stock absolutely go leaf. quick and easy. you can still go leaf on the lower version it's just a bit more hassle. if 4 link is where you headed look at the triangulated version that removes the panard bar. My panard bar is the lowest thing on my rear and can be damaged. the triangulation uses geometry to solve the side to side movement of the rear

Re: rear sus help
There is nothing wrong with your stock springs, you can remove three leafs and put a set of Bilstine shocks and iti will ride great

Re: rear sus help
They do not have a website. They typically have a full page ad in the trucks mags or used to. You can probably get their number by doing a search for JPL Trucks. If not I can send it to you on Friday.
How low do you want your truck? If you go with the 4 link you will need to know what spring rate you want for the coilovers. The leafs will get you a 5-6 inch drop with an axle flip. If you are wanting lower then the 4 link is your answer. In my opinion going lower though would require air ride or you stand a good chance of leaving parts on the street after speed bumps. |

Re: rear sus help
i'v read the thread, and all i have to say is, if you want to save sme cone, than use the stock leafs you have with 2 over loaders, but trust me, a good 4-link will put you in front everytime....looks better, easer to set wide rims, makes better for comfort.....so on, so forth.....as mentioned, there are lots of sights that give all measurements that you might need......but for me, 4-link is the way to go, with saying that, im running leafs in my 55 daily driver, it was a cheap way to go that holds up to what my truck will go through.

Re: rear sus help
Here is a Cheep Cherokee rear leaf springs and parts from the Jeep store shackles and the front hangers for a Jeep, they are the same width as the spring welded to a boxing plate on the frame. These parts do not have to come from one source and you can spend your money on some good shocks, I like Bilstine
