Jeep Spring Over (SOA) Conversion

Once you start wheeling in a stock Jeep, it doesn't take long before you start wanting more ground clearance. There are a number of ways to do this on a leaf-sprung Jeep, including body lifts, shackle lifts, spring lifts, and coil conversions. However, for the best combination of ride quality, ground clearance, and cost, the best option may be a spring-over-axle (SOA) conversion.

For those not familiar with SOA, the concept is pretty simple. Most Jeeps, including CJ's and Wrangler YJ's, come from the factory with the axles sitting on top of the suspension leaves. An SOA lift takes the axle off the top of the springs and reattaches it underneath the springs. The amount of lift gained is the sum of the axle tube diameter, the spring pack thickness, and both the old and new spring perches. On a Jeep Wrangler YJ, this generally amounts to around 5.5". Because the lift itself potentially uses all stock parts, cost is kept to a minimum. Because it uses your stock, mostly-flat springs, the factory ride quality is maintained.

We've got Jeep SOA kits ranging from complete systems with new springs, to economical parts kits for the do-it-your-self person.
