That mystery clunk under your Bronco isn't always trail damage. Knowing the difference between a loose skid plate and a factory transfer case defect can save your drivetrain.

Trail noise usually sounds like:
- Sharp metal-on-metal pops during suspension flex.
- Rattling from loose bolts or captured rocks in the skids.
- Thumps from bottoming out on the bump stops.

Factory recall symptoms (Transfer Case):
- Heavy mechanical grinding during shifts.
- Persistent knocking only when engaged in 4-Hi or 4-Lo.
- Difficulty disengaging 4WD.

Crawl under and torque your suspension bolts first. If everything is tight and the noise stays internal, check your VIN for the latest TSBs or recall notices. We’ve seen a handful of these 6G Broncos come through our Utah shops with both issues. Don’t ignore the sound: diagnose it before it leaves you stranded on the rocks.

If you’re moving up to 37s or 40s, you aren’t just adding ground clearance: you’re adding massive rotating mass and leverage against your factory braking system.

It’s simple physics. Larger tires act like a longer lever on your axles, making it significantly harder for stock calipers and rotors to slow you down. On steep Utah descents or crawling down technical ledges in Moab, that extra weight turns into momentum that stock brakes weren't designed to handle.

Heat soak and brake fade are real risks when you're running heavy rubber on factory hardware. Upgrading to a Big Brake Kit increases your clamping force and heat dissipation. For older rigs or heavy builds, a Hydroboost conversion can provide the line pressure needed to bring those 40s to a dead stop with confidence.

Don't build a rig that can go anywhere but can't stop when it counts. We’ve been dialing in 4x4 systems for over 30 years at our Salt Lake City and Park City shops. If you're planning a big tire upgrade, let’s talk about your stopping power.

If your lifted Toyota feels twitchy on the highway, your caster is likely the culprit. Lifting a Tacoma or 4Runner alters the factory steering geometry, often leaving you with a wandering feel that is exhausting on long drives.

We solve this using SPC adjustable Upper Control Arms or, for the ultimate setup, Icon Billet UCAs. These aren't just for looks: they are engineered to restore proper caster and provide the clearance needed for larger tires and high-end shocks.

• SPC arms offer the adjustability needed for a perfect alignment.
• Icon Billet arms bring unmatched strength and precision to your front end.
• Both restore steering stability and eliminate that highway wander.

Stop fighting the wheel. Get your geometry right at our Salt Lake City or Park City locations. 🛠️

The 40-inch club looks good on paper, but the mechanical reality is a different beast. Putting 40s on a modern Bronco isn't just about clearance; it’s about survival.

Stock components aren't built for that much rotating mass. If you’re serious about reliability on the trail, you need:
- Chromoly axle shafts to prevent snaps under load
- Precision re-gearing to get your power back
- Beefier steering components to handle the extra leverage

We’ve been building Broncos for over 30 years. We know exactly where the breaking points are and how to reinforce them. If you’re ready to step up, do it once and do it right.
