solid axle conversion faq's
1988-1998 chevy/gmc 4wd
Q - What trucks will the 60010 and 60011 conversion kits work on?
A - All 1988-1998 K1500 / K2500 / K3500 4wd
Q - What if my truck is a 2wd?
A - You will use ORU Conversion 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.
* 1977-1979 Ford F350 Dana 60 - 32.5" spring pad width (center to center)
* 1986-1997 Ford F350 Dana 60 - 36.5" spring pad width (center to center)
* 1977-1979 Ford F250 Dana 44 - 32.5" spring pad width (center to center)
Q - Can I use a GM front axle?
A - Yes, but it is more work. GM solid axles require a transfer case that has the front driveshaft drop on the passenger side...your truck has the drop on the driver 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 option for your conversion.
* If you choose the standard option GM 1973-1987 front springs can be used. ORU Solid Axle Conversion kits use 9/16" for the springs so spring bushings and sleeves from the 1988-1991 K3500 must be used.
* The premium ride option utilizes a custom made spring that is 6" longer and moves the shackle back 6" for a better ride. These are custom springs that 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 4" to clear a 35" tall tire.
Q - What if I want to keep my truck 6 lug?
A - The parts to make this happen (convert from 8 lug 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 and rear. These axles are very cheap and easy to find.
Q - How much lift does the conversion kit add?
A - The kit, by itself, will add 3" to whatever size spring you choose. For example... Kit=3" Lift, Leaf Spring=4" Lift, 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 driveshaft will have to be made. You can either have a local or mailorder company make a new one for you but we do recommend a long travel CV front driveshaft.
Q - Do I have to modify my exhaust?
A - Yes, The exhaust will need to be modified to clear the passenger side shackle hanger.
Q - How long does it take to complete the Solid Axle Conversion?
A - Depending on your abilities, experience and the options you choose, the conversion should take about 20-40 hours to complete.
Q - What do I do about my ABS?
A - We do not currently offer a retrofit kit for ABS on this generation. Dynatrac may be able to help. You can reach them at (714) 596-4461
Q - Is this a complete bolt on kit? Is welding required?
A - There is drilling required. Welding will only be needed if you plan on running single shocks (the lower shock mount needs to be welded in place).

- * Dual Shock Hoops
- * Trac-Bar
- * Brake Lines
- * Shocks
- * Hydraulic Ram Steering Assist
- * Torsion Sway Bar
Q - Do I have to use Hydraulic Ram Steering Assist?
