ORU 88-98 GM Solid Axle Conversion FAQ’s (60010 & 60011)
Q. What trucks will the 60010 and 60011 kits work on?
A. All 88-98 K1500's, K2500's, K3500's.
Q. What if my truck is 2wd?
A. Refer to kit 60009
Q. What is the difference between the 60010 and 60011 kits?
A. The 60010 kit uses an axle with a 32.5” spring pad width. The 60011 kit uses an axle with a 36.5” spring pad width. Below is a simple breakdown of axles.
* 77-79 Ford F350 Dana 60 32.5” spring pad width (center to center)
* 86-97 Ford F350 Dana 60 36.5” spring pad width (center to center)
* 77-79 Ford F250 Dana 44 32.5” spring pad width (center to center)
Q. Can I use a GM front axle?
A. Yes, but its more work. GM solid axles require a transfer case that has the front driveshaft drop on the passenger side, and your truck has the drop on the drivers side like a Ford. You will have to install a GM transfer case. All GM axles use the 60010 kit.
Q. Do I have to use crossover steering?
A. Yes, crossover steering has to be used with the solid axle swap since the factory IFS steering will not work. Note that the steering from the donor axle will not work either.
Q. What springs do I use?
A. Here you will need to decide if you want the standard or premium ride kit for your conversion.
* If you choose the standard kit, GM 73-87 front springs can be used. ORU Solid Axle Conversion kits use 9/16 bolts for the springs, so spring bushings & sleeves from the 88-91 K3500 must be used.
* The premium ride kit utilizes a custom made spring that is 6" longer and moves the shackle back 6” for a better ride. These springs must be purchased from ORU.
Q. What is the minimum lift spring I can use?
A. The smallest lift spring we recommend for this kit is a 4” to clear a 35” tire.
Q. What if I want to keep my truck 6 lug?
A. The parts to make this happen (convert front axle from 8 to 6 lug) are hard to find. We recommend swapping the rear axle of the truck to a GM 10.5” 14 bolt so you can be 8 lug front & rear. These axles are very cheap and easy to find.
Q. How much lift does the kit add?
A. The kit, by itself, will add 3” to whatever size spring you choose. For example Kit=3", Leaf Spring=4", Total lift= 7"
Q. Do I have to change my steering box?
A. No, the factory IFS steering box is fine.
Q. What do I do for a front driveshaft?
A. A complete front shaft will have to be made. You can use a local shop, or have any mail order driveshaft company build it for you. We recommend a long travel CV front driveshaft.
Q. Do I have to modify my exhaust?
A. Yes, the exhaust will have to be modified to clear the pass side shackle hanger.
Q. How long does the conversion take to complete?
A. Depending on your abilities, experience and options you chose, the kit should take 20-40 hours to complete.
Q. What do I do about my ABS?
A. We currently don't offer a retrofit kit for ABS on this generation. Dynatrac may be able to help, so give them a call @ 714-596-4461
Q. Is the kit bolt on? Is there any welding required?
A. There is drilling required before the kit can be bolted on, and welding will only be needed if you plan to run single shocks. (the lower shock mount needs to be welded in place)
Q. Are there any upgrades available?
A. We have several parts that are optional with this conversion. Dual shock hoops, Trac Bar, Brake Lines, Shocks , Hydraulic Ram Assist, and a Torsion Sway Bar.
Q. Do I have to use a hydraulic ram assist?
A. ORU recommends a ram assist if you plan to run a tire larger than 35” tires.
