1960-87 Chevrolet & GMC Pickup Bolt-in IFS Package
BOLT-IN FRONT STEER IFS '60-87 GM/GMC Pickups -- A total bolt-in package http://www.jimmeyerracing.com/pu6.html Using stock-existing factory holes, this easy-to-install, bolt-in or weld-in IFS kit featuring ‘78-88 front-steer Impala spindles, 12-inch diameter (Impala) rotors, calipers, and balljoints will give you a 5-on-5-inch diameter bolt pattern. The stock crossmember will unbolt and is replaced with a new 2 x 4 x .188-inch wall bolt-in crossmember that holds a ’83-87 T-Bird power rack-and-pinion steering unit. Either a stock, power GM gear-box pump or GM rack pump is compatible to operate the rack. C-channel frame stiffeners, that bolt inside the frame, are also included in the kit. Modifications to the bottom of the steering column will be necessary to connect to the rack spline, or replace it with an ididit column. http://www.jimmeyerracing.com/images/ifs7a.jpg The stock 64 1/2-inch front track width is narrowed to 62 1/2-inches with the new IFS kit. The kit features D.O.M. tubing upper-and-lower A-arms (1 1/4-inch dia. X .156-inch wall lower arms and a 1-inch dia. X .156-inch wall upper arm). The aluminum, adjustable coilover shocks with powder coated springs are attached to a three-position upper mount and a two-position lower mount that offers you about 4-inches of movement for the stance you like best! Dropped spindles, custom track widths, 1-inch diameter sway bar, steering linkage kit and column are just part of the options available. |

I've wondered how that would work out. Ride height, handling, weight, adjustability...

I have this kit for my 60 Apache but haven't gotten it installed yet. The kit that's shown is actually for 63-87 trucks. For the 60-62 frames a plate has to be welded over the big holes on the inner frame and then the motor mounts get welded to that. Also because of the frame differences the doubler plate is not included.
Aside from items I mentioned I think the rest of the kit is the same as pictured in the Jim Meyer photo. The workmanship looks to be top knotch. I did do a test fit on my frame when I got the kit. Fit was good. http://homesteaders.us/JM1testfit.jpg http://homesteaders.us/JM2testfit.jpg |

Yet another nice front kit for our trucks. I like how the upper balljoint plate is welded inside slots in the A-arm tubes. Nice clean look thats also very strong. The upper arms from the kit I used are built the same way.

Jimmy builds some good stuff. I had their products on a '49 F1 I had. I really like that you can move the upper shock mount to gain a little more travel when lowered..

How much are their base kits?

The kit looks great. Personally I would use one of our Forum Vendors kits first.

The fabrication looks nice, but I'm always critical of these suspension kits. I always like to talk to the engineers/fabricators who designed them before dropping a bunch of cash.
I wonder how the actual geometry of the suspension, through the range of motion, compare to the factory suspension? I don't really like the use of heim joints on the upper control arm instead of bushing. The inherent geometry of the upper arm constrains it to only rotate about a single axis. I do realize that they are probably installed to allow for changes in camber, however their orientation is not really correct, as the mounting point will be closer together or further apart as you adjust them in and out. In my experience building cars heim joints are too harsh for street use and fatigue too quickly, especially on a heavy vehicle like a truck. A bushing would be better. Plus don't out 60-66 trucks already use solid bushings form the factory? And aren't they greasable, unlike these? I would like it better if the mounting point of the upper control arm to the crossmember was adjustable too; In-out and up-down. As you change static ride height with the coilover mount you will also drastically change the static and dynamic suspension geometry. Often times you want to be able to move the pivot point of the upper control arm down and in toward the center of the vehicle to lower the roll center and also to ensure that you don't increase positive caster as the suspension compresses, or that the rate of camber change isn't too aggressive. Sorry to be critical, but I think its always good to ask questions and know what you are buying before you buy it. I'm not saying it isn't a great piece, its just my engineering nature to question. :) |
