Hey Steven, thanks for reaching out. No, that’s actually one of the things I like most about the SumoSprings Solo # SS39PJ. These replace the factory front bump stops with progressive microcellular urethane springs, so they get firmer as they compress instead of giving you the abrupt hit you get when a factory bump stop makes contact. They also provide up to 1,000 lbs of support at 50% compression, helping control front-end movement, body roll, and bottoming out while absorbing some of the vibration and harshness from rough roads. They’re a custom fit for the 2022-2026 Ineos Grenadier.

For a Grenadier that sees rough roads, off-road driving, a winch or other front-end accessories, I really like this upgrade. Each spring works independently, so they help stabilize the vehicle without tying the two sides of the suspension together. They’re also completely maintenance-free with no air lines, pressure checks, or leaks to deal with, and installation uses the existing mounting points with no drilling. Once they’re on, there’s really nothing else to mess with.

Are you mainly looking to improve the ride on rough roads, or are you adding extra weight up front like a bumper or winch?
