We're working to restore these instructions from our previous website. Please bear with us. If you need immediate assistance, contact sales@artecindustries.com.

This Kit requires Welding and Fabrication skills,If you are not confident in your abilities please have this product installedat an Off-road shop.

 

Tools Required :

Safety Glasses, Jack, Jack Stands, Socket Set, Wrench set,framing square(X2), Tape measure, drift punch, Hammer  Angle finder, Welder, Welding PPE,  Cutting tools

(Example Sawzall, Grinder, Cutting Torch, Plasma cutter)

Step 1:

Chock the front wheels of the vehicle.

 Step 2:

Break the rear lug nuts free

(Do not completely remove the lugnuts.)

 Step 3: 

Jack up rear of the vehicle and set the frame securely on jackstands.  Keep the Jack under the axle

(You'll need to us this to helpcontrol the axle dropping later on.)

 Step 4:

Remove lug nuts and wheels from vehicle.

 Step 5: 

Unbolt the shocks, rear track bar, Sway bar end links, andrear driveshaft from the axle housing. 

 Step 6:

Use the jack to slowly lower the axle down the coil springsshould be able to be pulled out easily 

(Keep an eye on the rear brake linemake sure it does not get tight or stretch.) 

 Step 7:

Use an angle finder to check the angle of you current springplates.  (Recordthis number for later on)

Hold a framing square on the center of the coil spring perchesand take a measurement from center to center  (Record this number for later also)

Now cut off the current spring plates from the axle andgrind the area smooth to prep for welding.

 Step 8:

Install the coil plate, Use the center to center measurement you took in step 7 to position thecoil plates ,  Now  using the angle finder  place it on top of the coil plate and tiltthe coil plates to get the angle you had recorded in step 7.   Then Weld the coil mounts into place.

(The coil plate is offset towardsthe front of the vehicle, So make sure the larger part of the plate hangs overthe front of the axle. )

 Step 9:

Weld the center tubes to the coil bucket (make sure they are flush with the bottom of the coil bucket when welding into place.) Tackweld the supplied bolt from the HK0050 kit to the bottom of the small rounddisk.  Weld the Small disk on top of theround tube (with bolt threads facing up)  The big disk will be used in next step.

 Step 10:

Paint the coil brackets with some self-etching primer andpaint (We find we get the best results with rustolem paint.)

 Step 11:

Insert the coil springs onto coil plates,  Now slip the large disk inside of coil andhave the bolt from the small tube slip through the hole.  Use the nylock nut from the HK0050 kit totighten the round disk.  Once this is doneyou can raise the axle up into position with the jack.

 Step 12: 

Install the shocks, Sway bar links , Track bar and driveshaft onto rear axle. Tighten the bolts finger tight .

(You may need to use a drift punchto help getting bolts aligned when reinstalling the track bar and shock bolts)

 Step 13:

Install the wheels and tighten the lug nuts (do not torque them yet) Raise the Vehicle up off the jack stands with the jack, Removethe Jack stands and lower vehicle onto the ground . 

 Step 14:

Torque shock bolts and track bar bolts to 75ftlbs  and sway bar link bolts to 40ftlbs Then lug nutsto 95ft lbs. and  U-joint strap  bolts to 17ftlbs

 

 After 50 miles or a few trail runs (whichever happens first)  check all bolts for proper torque .
