72-93 Axle Swap Coil kit (3rd gen axle / 2nd)

$3,404.13

   This is a Bolt On Coil Spring, Link Suspension conversion for a 1972 - 1993 dodge truck frame (1/2 ton, ramcharger, 3/4 or 1 ton, 2wd [*] or 4wd) designed to utilize a donor axle and coils from a 03-12 2500 or 3500 dodge (can be made to work with a 94-02, but 03-12 preferably** see below). 4-8” of lift height (based on spring choice and coil adapter height).
   It will get rid of all existing original suspension and it’s traits like stiff leaf springs, and replace them with a super strong, long arm 4 link with track bar, including new ultra heavy duty steering tie rod and drag link. 
   A conversion with stock coils (gas preferred) from a donor axle will be similar to a 4” lift. Coil spacers or lift coils can raise things from there. This will greatly improve and modernize the ride quality and handling of the front of your truck. 
   Parts are powder coat wrinkle black, request raw in notes if desired, custom colors available on request.

   * A 2wd frame will require a 4x4 engine crossmember. It’s not the worst to change or find, and we have our own 3 piece version to avoid junkyard scrounging and facilitate in-truck oil pan removal coming soon. Otherwise these frames are the same or very similar and are all good strong candidates for a build, regardless of them originally being diesel or gas. A 4x4 trans crossmember is also needed but it’s the easiest part to get and convert. We also have some options and info to make this work. 
   ** A 2nd gen axle had a central axle disconnect that isn’t desirable, it also doesn’t have as high of a pinion to help driveshaft angles. It’s brakes aren’t as big as the 3rd gen. And although they are inexpensive and easy to find, so are the later axles. We have not thoroughly tested with the earlier axle like we have with the later. The 3rd gen axle doesn’t have the CAD, has a high pinion, and has a better suited track bar bracket. It is an overall heavier duty and physical weight axle. It can be trussed underneath to address one of the few foundational weak links (not found until you are jumping a heavy truck). Both axle sets need converted to a spin free hub design to be the reliable non maintenance axle they should be, this also gets you lock in/out hubs. we have a kit available for the 94-99 axle as well as a kit for 00-12. Additionally they each should be converted to a “good” ball joint (moog or equivalent “lifetime” replacements are JUNK) we have a couple good options that are actually a part you can expect to be a lifetime part (at least one great option is not available for the 00-02 axle, but good options do exist too). Regardless of the axle, and due to the overall weight difference between a first gen and the later trucks, we recommend the coils that came from a gas truck 2500/3500. The gas will ride the softest and sit a little lower, the diesel coils are the stiffer and slightly taller option and do still work well and provide a good ride. 
***Caster Eliminator Plates will be chosen based on the axle you choose to go with. All axles from 03-13 will use this version. 94-99 will use this version. 00-02 are a little bit of a toss up, on paper using the first mentioned 03-13, but somewhat often found with the 94-99 sizing. The difference is on the axle in the mounts for the lower arm. It is most easily checked by a front to rear measurement of either/both the small slot where the lower arm bolt passes through or the outer cage for the original caster cam washer.
