Product Description

The Flatout Suspension GR Plus was created solely for customers wanting the brute strength and toughness of a rally-prepped suspension but who want to save some money to achieve approximately 2-inches of lift and partake in off-road adventures without needing a full-blown rally suspension. This is the perfect alternative to a typical spring/strut combo that offers no adjustment and is a superior option to adding strut spacers to worn OEM suspension. Install, adjust, done.

Q: Should I get comfort or overload springs?
A: The ONLY time we recommend overload springs is for rear tire carriers, towing, or both.

Q: Can I get different spring rates as I carry a lot of gear and tow?
A: Absolutely! Just let us know the rate you'd like in the order notes.

Q: Can the shocks be rebuilt, or do I have to buy replacements?
A: These are completely rebuildable, by us or anyone with nitrogen.
