Synergy MFG Suspension Systems use a synergistic approach, meaning the combined effect of the components is greater than the sum of the individual parts. The overall performance of the system is the most important factor when we are designing components to work together. Synergy MFG Suspension Systems are complete systems for your vehicle and include all necessary components for the lift height and performance advertised.
The Jeep Gladiator JT Starter System is a coil spring 1 & 2-inch lift designed around 37-inch tires for Rubicon models and 35-inch tires for non-Rubicon models (See fender and bump stop spacing recommendations below). This system is designed to be the most capable performance coil spring lift on a budget, with room to upgrade as funds allow. For more complete 2-inch lift systems, see the Stage 1 or Stage 2 systems.

Features:
Multi-rate, progressively wound coil springs increase lift height to 1 & 2 inches over stock. Front and rear coil springs are all new and have been designed specifically for the JT platform. Like OEM, the coil springs are unique lengths for each corner of the vehicle to compensate for weight distribution and prevent leaning. Longest in class free length prevents coil springs from coming unseated at full articulation and coil spring block height has been designed around optimal bump stop spacing for the lift height and tire size. Industry first “closed and ground” front coil springs ensure perfect fitment with the included front lower coil spring isolators. Our coil springs are guaranteed to resist bowing and have a lifetime guarantee against sagging/breakage.
Front and rear bump stop spacer kits are included to provide the necessary clearance required for larger tires. front bump stop spacing is adjustable from 2-4 inches in 1-inch increments without having to remove any hardware.
Front and Rear sway bar link relocation brackets maintain factory sway bar geometry to allow full articulation of the suspension and maintain compatibility with stock wheels.
Suspension components feature an abrasion-resistant powder coat finish for maximum durability and corrosion resistance.
100% bolt on components assure an easy, trouble free installation with the use of basic hand tools.

Installation Instructions
Notes:
If using Stock Shocks, this kit MUST be used with 8817 JT Shock Relocation Brackets.
If installing on a DIESEL Jeep Gladiator, 8861-11 Synergy Jeep Gladiator Rear Sway Bar Links MUST be used Instead of 8808-01 rear Sway Bar Drop Brackets.
Synergy MFG coil springs lift the vehicle the advertised height over stock based on a fully loaded JT Rubicon. Other JT models will see more lift over stock. These coil springs do not lift taller than advertised. The stock rake based off the Rubicon model is kept to retain its load carrying capacity. If you prefer the vehicle to sit level when unloaded, we recommend a 1 or 2 Inch taller spring in the front versus the rear. Adding a small coil spacer to the front (up to 3/4 inch without affecting up travel or causing coil bind, 8017-075) will help as well.
Synergy MFG is not responsible for maintaining finish of products. Environmental factors will affect rate of corrosion and wear for items advertised to be corrosion resistant. We recommend using protective coatings for all items that will see extended outdoor and off road use. We have had great experience with the Fluid Film product and recommend it and similar products for any items susceptible to damage from corrosion. It is great for keeping double adjuster assemblies working like new and protecting shock bodies from the elements.
We always recommend manually disconnecting your sway bar links in any offroad application on both Rubicon and non-Rubicon models
Factory sway bar disconnects do not allow for enough articulation to prevent damage to your track bar mount or electronic disconnect
Wheel and Tire Fitment:
Recommended tire size is limited by fender clearance. With higher clearance fenders or trimmed fenders, larger tires may be fitted. Bump stop spacing should be matched to the collapsed length of the shocks. Mismatched bump stop spacing and shocks will limit the available travel from the system.
Recommended tire size and wheel backspacing:
Gladiator Model Fenders Wheel Backspacing Recommended Tire Size for 1″ Springs Recommended Tire Size for 2″ Springs
Rubicon/Mojave Unmodified Stock Stock Wheels 35 Inch 36 Inch
Rubicon/Mojave Unmodified Stock 4.5 Inch or less 35 Inch 35 Inch
Rubicon/Mojave Trimmed stock or High Clearance Stock Wheels 35 Inch 37 Inch
Rubicon/Mojave Trimmed stock or High Clearance 4.5 Inch or less 35 Inch 37 Inch
Sport Max Tow Unmodified Stock Stock Wheels 33 Inch 35 Inch
Sport Max Tow Unmodified Stock 4.5 Inch or less 33 Inch 35 Inch
Sport Max Tow Trimmed stock or High Clearance Stock Wheels 35 Inch 37 Inch
Sport Max Tow Trimmed stock or High Clearance 4.5 Inch or less 35 Inch 37 Inch
Non-Rubicon Unmodified Stock Stock Wheels 33 Inch 35 Inch
Non-Rubicon Unmodified Stock 4.5 Inch or less 33 Inch 35 Inch
Non-Rubicon Trimmed stock or High Clearance Stock Wheels 35 Inch 35 Inch
Non-Rubicon Trimmed stock or High Clearance 4.5 Inch or less 35 Inch 37 Inch

These recommendations will result in no or very little rubbing at full articulation and steering. Some stock bumper configurations may require more trimming than others. Less than our recommended bump stop spacing can be run (up to 2 inches of bump stop spacing), but fenders and inner fenders will need to be trimmed for additional clearance.
Backspacing recommendations are based on wheel offset and wheel spacer combinations. With stock wheels, adding wheel spacers is equivalent to running 4.5 inches or less of backspacing.
