Details & Inspection Notes
GBF035-2-B drops both the front and rear 1" on coil springs and runs RideTech HQ adjustable shocks at every corner rather than mixing a coilover with a leaf spring. The front sway bar is a 1.25" solid bar, and the rear is a 1.00" solid bar that is itself adjustable, so you can fine-tune roll stiffness after the kit goes on.
What's in the kit
Control arms are tubular steel finished in black powdercoat, riding on Delrin bushings, with tubular frame braces included for chassis stiffening. UMI supplies Grade 8 hardware for the install; brake components are not part of this package, so plan on sourcing those separately.
What to check before buying
Because both ends drop the same 1" on coil springs, expect a more even stance change than a kit that lowers only the front. The adjustable rear sway bar gives you some room to tune handling balance after installation rather than locking it in at one setting.
Common questions
Does this kit lower both ends the same amount? Yes, both the front and rear coil springs drop ride height 1".
Are the shocks adjustable at both ends? Yes, RideTech HQ adjustable shocks are used front and rear.

Suspension Setup & Installation Checklist
- Inspect top mounts, damper seals, bushings, and ball joints prior to fitment.
- Set initial spring preload, collar heights, and damper rebound clicks symmetrically left to right.
- Torque all suspension control arm pivot bolts while the vehicle is at resting ride height (loaded suspension).
- Perform a complete 4-wheel laser alignment once ride height has settled to ensure optimal handling and tire wear.
