Let’s break down the core components, upgrade paths, and considerations for suspension systems in Jeep vehicles.

Why Suspension Matters for Jeeps

Suspension isn’t just about looks or lift height—it’s the system that connects your Jeep to the ground. It absorbs bumps, maintains tire contact, and determines how your rig performs off-road and on the pavement.

A well-designed suspension system improves:

Ground clearance
Articulation and flex
Ride comfort
Stability and control on uneven terrain

At TNT Customs, we take a holistic approach—custom tuning and proper geometry are just as important as lift height.

Key Suspension Components

Here’s a quick breakdown of the core suspension parts we work with in our builds and product line:

Coil Springs & Leaf Springs – Absorb shock and support weight.
Shocks (Dampers) – Control bounce and suspension movement.
Control Arms – Maintain axle alignment and articulation.
Track Bars – Center the axle under the vehicle after lifting.
Sway Bars & Links – Minimize body roll while driving on-road.
Bump Stops – Prevent over-compression of the suspension.

Each component plays a role in balancing performance, articulation, and comfort.

Jeep Suspension Basics FAQ

What’s the best lift height for my Jeep?

It depends on your use. For daily driving with occasional trails, a 2.5″-3” lift is usually perfect. For hardcore off-roading, 4”-6” or more with long arms may be better.

Will lifting my Jeep ruin ride quality?

Not if done properly. TNT Customs uses tuned shocks, correctly angled control arms, and geometry correction brackets to preserve or improve ride quality.

Do I need to upgrade my driveshaft or steering with a lift?

Yes, for lifts over 3″, we typically recommend a double cardan driveshaft and steering upgrades to maintain alignment and prevent driveline vibration.

Can I install a TNT suspension kit myself?

Many of our kits are DIY-friendly for experienced Jeep owners. However, we offer installation at our Cheyenne shop and recommend professional install for advanced kits like long arm suspensions.

What’s the difference between short arm and long arm suspension?

Short arm kits use factory-style control arms. Long arm kits use longer control arms that improve ride quality, articulation, and stability—ideal for serious off-roaders.

What suspension upgrades give the best articulation?

Our long arm kits, paired with TNT-custom shocks and high-clearance skid systems, provide unmatched articulation without sacrificing durability.

How often should I inspect my suspension?

Check your Jeep’s suspension every oil change, especially after wheeling trips. Look for loose bolts, bushing wear, shock leaks, and spring sag.
