Teraflex Sport ST3 3.5" Suspension Lift for 18-25 Jeep Wrangler JL Unlimited
The Teraflex Sport ST3 3.5" Suspension Lift offers the ultimate combination of off-road performance and on-road handling. This complete suspension lift was designed specifically for the four-door Jeep Wrangler Unlimited JL. With the ST3, Teraflex was able to accomplish their goal of reducing NVH (Noise, Vibration, and Harshness) in a 3.5” lift kit. They thought of every detail when compiling this kit. Teraflex includes their Front Control Arm Geometry Correction Brackets for improved suspension travel and driveline angle. In order to accommodate every trim level, Teraflex also includes Bump Stop Strike Pad Shims for Sport, Sahara, and Rubicon models. For the best stability and handling, the ST3 is also available with Teraflex’s Falcon SP2 Monotube and Piggyback Shocks. Falcon SP2 shocks are precision-engineered for a specific vehicle and lift applications. They feature Teraflex’s proprietary Volume Optimized Damping (VOD) for race-inspired performance and comfort. Teraflex backs their lifts with a Limited Lifetime Warranty.

Teraflex Sport ST3 3.5" Suspension Lift Reviews
I installed this lift kit by myself and was the first lift kit I have ever done. Given I was by myself it took about 2x the stated time, but I worked methodically to ensure everything was torqued correctly. Everything fit as required, the kit states in a few places that it is a "complete bolt on". This isn't entirely true, I had to drill a hole in the rear track bar bracket and two in the front track bar bracket not that it was terrible (would have still gotten the lift even if I knew this). This lift gave me about 3.75" of lift on my JL 21' Rubicon 4 door. After install the steering wheel was off center about 1/5 of a turn so you will have to adjust that. Ride quality is excellent and slightly better than stock. As far as the geometry of this kit, it is very good. I took it in for an alignment after words and only the toe of one front tire needed adjusted even though it wasn't off far. Ended up with Caster of 5.4 and 5.5 degrees. Went to 37" Patagonia's and Falcon 3.3 shocks. I definitely suggest twisting towards the soft setting prior to installing the shocks and running the Pat's at 35-36psi. A couple other notes, I would also say this is about as high of a kit as you can go without extending break lines, locker cables and breathers. It fits in my normal size garage by about 1" with a bestop ultra top.
Falcon 3.3 shock blew out before I even took it on a trail.
