These shocks provide a 2-inch lift over OEM height, with enhanced suspension travel for improved handling on and off the road. The adjustable damping allows you to fine-tune your ride, ensuring maximum comfort and control in a variety of conditions.

Unlike other shock and spring combos, the TR Series offers an OEM-style look and feel, ensuring your ride remains sleek and factory-finished, while still delivering top-tier performance. These shocks are compatible with any spring designed for OEM-style shocks, including lift and overload springs, giving you the flexibility to further customize your setup.

With maintenance-free construction, the TR Series is the ideal solution for those who want a complete, hassle-free suspension upgrade.

By reusing your OEM springs, top mounts, and hardware, you get the full capability of a premium suspension setup while cutting down unnecessary costs. It’s the perfect solution if your factory components are still in good shape and you’re looking to maximize value without sacrificing results.

Backed by Flatout Suspension’s reputation for durability and performance, this setup keeps things simple, reliable, and effective.
