Here's some quick instructions on how to install upgraded soft springs on you 24v Grave Digger Power Wheels.

You'll need:

Two 4.5mm Hex wrenches

A phillips screwdriver

A round file (sandpaper or a utility knife might work as well)

Upgraded soft springs - (available by emailing GraveDiggerUpgrades@gmail.com , cost is $45 for an un-coated set of 4, $65 for a professionally powder coated set of 4. Free shipping in USA)

Step 1: Remove the Old Shocks

I recommend putting the vehicle on jack stands for this. It's heavy and those springs do hold the weight.

The shock absorber assembly is held on by two hex bolts. You can remove both sets of screws and take the shock off completely, or you can attempt to just remove the top and slide the new spring on while the bottom stays attached. The screws are kind of awkward to get to, so it might be easier to only undo the top.

You'll need to do this to each of the 4 shocks, but I would do them one at a time.

Step 2: Disassemble the Shock Absorber and Replace the Spring

This step is pretty simple. You can just unscrew the big metal washer and slip the old spring off, slip the new spring on. You might want to tighten the plastic cap that goes around the piston while you're in here. All 4 of mine were loose from the factory.

It also looks like they would function with r/c shock fluid, but they work well enough without it that I haven't actually tried it yet. If someone fills their shock tubes with fluid, let me know how it goes!

Step 3: Enlarge Conduit Holes Into Body

If you look at the backside of the motors, there's this green pipe/conduit that protects the wires as they go up into the body. These pipes will move up and down with the new suspension flex. The holes on mine were very tight from the factory, so I widened them up a bit.

Unscrew the three screws holding the conduit to the motor housing. Then unplug the motor wire under the seat. Pull the conduit and wires out and away from the body. Now you can enlarge the hole a bit with a round file, sand paper or a knife. Doesn't need to be too big, just enough that the green conduit can slide freely up and down. Then reassemble.

Do this to both sides on the rear.

Step 4: Get Bouncin'!
