Rear TJ coil Perches and retainers (pair)

This Kit requires Welding and Fabrication skills, If you are not confident in your abilities please have this product installed at 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 lug nuts.)

 Step 3: 

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

(You'll need to us this to help control 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, and rear driveshaft from the axle housing. 

 Step 6:

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

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

 Step 7:

Use an angle finder to check the angle of you current spring plates.  (Record this number for later on)

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

Now cut off the current spring plates from the axle and grind 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 the coil plates ,  Now  using the angle finder  place it on top of the coil plate and tilt the coil plates to get the angle you had recorded in step 7.   Then Weld the coil mounts into place.

(The coil plate is offset towards the front of the vehicle, So make sure the larger part of the plate hangs over the 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.) Tack weld the supplied bolt from the HK0050 kit to the bottom of the small round disk.  Weld the Small disk on top of the round 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 and paint (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 and have the bolt from the small tube slip through the hole.  Use the nylock nut from the HK0050 kit to tighten the round disk.  Once this is done you can raise the axle up into position with the jack.

 Step 12: 

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

(You may need to use a drift punch to 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, Remove the 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 nuts to 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 .
