Important Note

To install lift components you will need to fully "droop" your suspension in the front and rear (not at the same time). We strongly recommend that the vehicle be placed on an automotive lift and that all appropriate safety precautions be taken to secure the vehicle while it is off the ground. Always use the necessary axle stands (or equivalent) to support the axle when the suspension components are disconnected, both for safety and to ensure the integrity of your suspension system during installation.

Front Axle Installation

Important Note

MetalCloak recommends replacing the factory drive shaft. The factory drive shaft binds at the transfer case side and is too short for additional travel. An aftermarket drive shaft clears the transfer case and is optimal for maximum travel.

Important Note

MetalCloak does not recommend powder coating your True Dual Rate Coils. The baking process used in powder coating can, in some cases, change the metallurgical properties of the coils, resulting in a loss of the coils' lift properties. Powder coating the coils will void any warranty stated or implied in relation to the coils.

Step 1: Remove Stock Components

Important Note

The brake line on the lower front control arms (driver and passenger side) must be removed from the bracket. It may be pried out or cut; be very careful not to damage the brake line.

Important Note

To help prevent strain on the brake lines, MetalCloak recommends clipping all zip ties attached to the brake lines.

Important Note

Disconnect any electronics attached to the axle (locker plug, front axle disconnect plug, etc.).

Step 2: Install Control Arms

Control arm length reference (measured eye-to-eye)
  Castor Angle Front Upper Front Lower Rear Upper Rear Lower
Factory Control Arms Stock 20 1/4" 24" 17 1/2" 20"
MetalCloak Lift 6 Degrees 19 3/4" 24" 17 1/2" 20 1/8"

Important Note

These control arm specifications are just starting points, measured eye to eye. All Jeeps are different. MetalCloak recommends seeing a suspension specialist for the correct control arm lengths for your Jeep.

Important Note

MetalCloak recommends installing one control arm at a time. Loosening — but not removing — all control arm bolts first will make removal easier.

Coil Isolator Information Guide

Important Note

MetalCloak's suspension systems include a unique coil design that utilizes upper isolators to position the coil. The table below will help you identify where to install the isolators included with your kit. You must remove the stock isolators before installing the provided coil isolators. If you have any questions, give us a call at 916-631-8071.

Coil isolator installation locations by Jeep model
Isolator Jeep Model Installation Location(s)
Tall Isolator JL Wrangler Non E-Torque Upper Front Passenger
JL Wrangler 4xE Upper Front Driver & Passenger
JL Wrangler Diesel Upper Front Driver & Passenger
JT Gladiator Diesel Upper Front Driver & Passenger
Short Isolator JK Wrangler (All Models) Upper Front Driver & Passenger
JL Wrangler E-Torque Upper Front Driver & Passenger
JL Wrangler Non E-Torque Upper Front Driver
JT Gladiator 3.6L Motor Upper Front Driver & Passenger
Rear Isolator JL Wrangler Non-E Torque Upper Rear Passenger
JL Wrangler 4xE Upper Rear Driver & Passenger

Step 3: Install Coils and Bump Stops

Important Note

Droop your suspension to gain access to the spring perch. Be sure to watch the ABS lines so they do not get over-extended and break.

Important Note

If the axle does not droop enough to allow the coil to be put in place, a coil compressor can be used to compress the coil to allow fitment.

Important Note

Your individual build may require an addition or removal of bump stop pucks for your tire size fitment.

Step 4: Install Outboard Shock Spacer & Shocks

Step 5: Install Front Track Bar

Note

Check side to side for axle center and adjust the track bar as necessary. Shortening the track bar will pull the body/frame to the passenger side, showing more tire outside of the driver side fender. Lengthening the track bar will push the body/frame to the driver side, showing less tire outside of the driver side fender. When measuring side to side, one half of the distance measured is the amount to adjust the track bar to get to center. For example, if the tire sticks out 1" more on the driver side, it would be necessary to lengthen the track bar by roughly 1/2" to bring the axle to center.

Step 6: Install Sway Bar End Links

Important Note

MetalCloak recommends using red Loctite on each of the upper spindles of the sway bar end links.

Step 7: Finalize Installation

Note

When lifting any vehicle, basic dynamics are changed. It is important to take your vehicle to a professional for an alignment after installation. Make sure the caster setting is adjusted for a lifted vehicle, not stock specs.

Rear Axle Installation

Step 1: Remove Stock Components

Important Note

MetalCloak recommends removing the bottom rear fender well plate for easier access to the upper shock bolts, using an 8mm socket wrench.

Important Note

Disconnect any electronics attached to the axle (locker plug, etc.).

Step 2: Install Control Arms

Control arm length reference (measured eye-to-eye)
  Castor Angle Front Upper Front Lower Rear Upper Rear Lower
Factory Control Arms Stock 20 1/4" 24" 17 1/2" 20"
MetalCloak Lift 6 Degrees 19 3/4" 24" 17 1/2" 20 1/8"

Important Note

These control arm specifications are just starting points, measured eye to eye. All Jeeps are different. MetalCloak recommends seeing a suspension specialist for the correct control arm lengths for your Jeep.

Important Note

MetalCloak recommends installing one control arm at a time. Loosening — but not removing — all control arm bolts first will make removal easier.

Step 3: Install Rear Coils

Step 4: Install MetalCloak Track Bar

Step 5: Sway Bar — Option 1

Use this option if your kit includes a sway bar drop bracket.

Step 5: Sway Bar — Option 2

Use this option if your kit includes a sway bar spacer instead of a drop bracket.

Step 6: Install Rear RockSport Shocks

Step 7: Install Rear Bump Stops

Each bump stop puck has two sets of mounting holes — one for the driver side and one for the passenger side — plus two labeled faces (Side A and Side B) that let you stack pucks to fine-tune bump stop height.

Step 8: Re-route E-Brake

Step 9: Finalize

Important Note

After re-installing the rear brake line bracket, bend the brake line bracket upward, toward the frame, to allow slack for extra droop.
