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 JT Stage 3 Suspension System is a coil spring 3 & 4-inch lift designed around 40-inch tires for Rubicon models and 37-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 in its price category.
Benefits:
- Coil spring suspension system to easily fit larger tires
- Improved off road and on road performance
- Includes all components necessary to get you on the trail
- Complete Bolt-on System for easy install
- Compatible with OEM wheels
- Lifetime Warranty on all hard parts
- Fully upgradeable to higher level systems
Features:
- Multi-rate, progressively wound coil springs increase lift height to 3 & 4 inches over stock. The front and rear coil springs 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 control arms are adjustable to allow for caster correction and re-centering of the front axle. The arms are made of 1.75" X .188" Wall 1026 DOM and feature maintenance free dual durometer bushings are used at both ends for uncompromised articulation.
- 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 track bar relocation brackets for increased strength and help retain factory ride quality.
- Front and rear sway bar link relocation brackets maintain factory sway bar geometry to allow full articulation of the rear suspension and maintain compatibility with stock wheels.
- Rear brake lines in the 3 & 4-inch kit allow the suspension to fully articulate without putting unnecessary stress on the lines and fittings.
- Suspension components feature a two-stage, 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.
- The 4 inch kit comes with front and rear adjustable track bars center the axles on the Jeep, maintains factory geometry and improves lateral stiffness compared to OE track bars.

Installation Instructions
Notes:
- Recommended addition of (8859-12) - Synergy Jeep JL / JLU / JT Sway Bar Link Disconnect Brackets on both Rubicon and non-Rubicon Models to maximize front wheel travel.
- Synergy MFG coil springs lift the vehicle the advertised height over stock based on a fully loaded JT Rubicon. Other JT models (non Rubicon/Mojave) 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 adding a small coil spacer to the front (up to 3/4 inch without affecting up travel or causing coil bind, 8017-075).
- 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.
- Synergy Anti-seize (4118) is recommended on all adjustable steering and suspension components for increased longevity.
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 3" Springs | Recommended Tire Size for 4" Springs |
|---|
| Rubicon/Mojave | Unmodified Stock | Stock Wheels | 37 Inch | 37 Inch |
| Rubicon/Mojave | Unmodified Stock | 4.5 Inch or less | 37 Inch | 38 Inch |
| Rubicon/Mojave | Trimmed stock or High Clearance | Stock Wheels | 37 Inch | 37 Inch |
| Rubicon/Mojave | Trimmed stock or High Clearance | 4.5 Inch or less | 39 Inch | 40 Inch |
| Sport Max Tow | Unmodified Stock | Stock Wheels | 37 Inch | 37 Inch |
| Sport Max Tow | Unmodified Stock | 4.5 Inch or less | 36 Inch | 37 Inch |
| Sport Max Tow | Trimmed stock or High Clearance | Stock Wheels | 37 Inch | 37 Inch |
| Sport Max Tow | Trimmed stock or High Clearance | 4.5 Inch or less | 37 Inch | 38 Inch |
| Non-Rubicon | Unmodified Stock | Stock Wheels | 35 Inch | 35 Inch |
| Non-Rubicon | Unmodified Stock | 4.5 Inch or less | 36 Inch | 37 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 | 37 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.
