Make a Great Grenadier Even Greater: Quick Wins from Shocks, Springs, Intake, Skids & Cooling
The INEOS Grenadier is already a go-anywhere hammer with a Swiss-watch vibe—body-on-frame backbone, lockers, and the right kind of stubborn. The fun part? You can still sharpen it.
Below are four upgrade paths that keep the factory character while adding capability where it counts. We’ll keep this light and breezy here; deep-dives are coming in separate articles.
1) Shocks & Springs: Control, Composure, and Load-Carrying
Upping the damper game adds authority over choppy washboard and big dips, letting the tires follow the terrain instead of pogoing. Pair that with quality lift springs and you get useful ride height, better approach/departure angles, and the spring rate to carry gear without the tail sag. Think: less head toss, more confidence.
- FOX Elite 2.5 Reservoir Shock (Front, Adjustable) — SKU FOX883-26-166
- Eibach Pro-Lift Kit Springs (Front & Rear) — SKU EIBE30-34-001-02-22
2) K&N High-Flow Drop-In Filter: Easy Breathing
A quality panel filter helps the B58 breathe easier without the drama. You keep the factory airbox’s water management and OE fit, while reducing restriction and service costs. It’s the five-minute mod you feel right away in throttle response.
3) Skid Plates & Underbody Armor: Because Rocks Don’t Care
Protection is performance when your adventures include rock ledges, ruts, and surprise stumps. Aluminum skid plates add a sacrificial layer between you and a long walk out, guarding catalytic converters, the transmission pan, exhaust, and tank.
- RIVAL Engine/Trans/Catalytic Converter Skid — SKU RLL2333.4501.1.6
- RIVAL Exhaust Skid — SKU RLL2333.4507.1.6
- RIVAL Gas Tank Skid — SKU RLL2333.4506.1.6
4) CSF Cooling Upgrades: Heat Is the Silent Power Thief
Long climbs at low speed, big loads, and hot ambient temps push any cooling system. CSF’s performance heat exchangers and radiators are built to add headroom—better cores, more efficient fins, and OE-quality fit. Translation: steadier temps and happier fluids when you’re working the truck hard. Browse our CSF lineup and reach out for fitment help on your Grenadier build.
What This Combo Feels Like
Better body control on corrugations, more confident line choice on ledges, a touch more eagerness off the line, and less worry about what’s lurking under the brush. In short: the same Grenadier, just “more Grenadier.”
