Upgrading a Travel Trailer
Upgrading your travel trailer for durability and reliability pays off in miles of worry-free travel, fewer roadside fixes, and better handling when hauling gear for fishing, hunting, or escaping the summer heat in southern Utah. Below is a practical guide to common and worthwhile upgrades — from heavy-duty tires to suspension and hardware improvements — and why they matter. Prime Tire & Auto Repair in St. George performs these upgrades and many more to help your trailer stand up to Utah roads and the demands of outdoor life.
Why upgrade?
Increased safety: stronger components reduce the chance of failures that lead to loss of control or trailer damage.
Longer component life: heavy-duty parts resist wear and fatigue better than stock pieces.
Better ride and handling: improved suspension and bushings reduce sway, improve axle alignment, and absorb road shock.
Lower maintenance and downtime: corrosion-resistant and heavier hardware reduces frequent replacements.
Recommended upgrades
Heavy-duty tires
Why: Travel trailer tires take heat, loads, and long highway runs; upgrading to a heavy-duty, trailer-rated tire reduces blowout risk and improves load capacity.
Brands to consider: Hercules Tire is a reliable option for trailer-specific tires with good load ratings and value.
Tip: Check load range and DOT manufacturing date; replace tires older than 5–6 years even if tread looks OK.
TPMS — Tire Pressure & Temperature Monitors
Why: Tire pressure and temperature monitoring systems provide real-time alerts for underinflation or overheating before a tire fails. This is critical on long highway runs or when carrying heavy loads to trailheads, lakes, or hunting camps.
Benefit: Extends tire life and prevents catastrophic failures.
Thicker aluminum shackles & heavier springs
Why: Stock shackles and springs on many trailers are sized for lighter loads. Upgrading to thicker aluminum shackles and higher-rate (heavier) leaf springs improves load carrying, reduces sag, and enhances stability when you’re carrying gear, boats, or ATVs.
When to upgrade: If your trailer consistently runs at or near its GVWR, or you’ve added weight (solar, batteries, water tanks), consider beefed-up springs and shackles.
Bronze bushings and wet bolts
Bronze bushings:
Why: Bronze bushings offer far better wear resistance and sliding properties than rubber or nylon in suspension pivot points. They help maintain correct alignment and reduce slop that causes noise and uneven tire wear.
Wet bolts:
Why: Wet bolts (greaseable bolts) let you lubricate pivot points regularly to reduce friction and corrosion. Together with bronze bushings, they significantly extend suspension life.
Equalizers with built-in absorption
Why: Upgraded equalizers that include shock-absorption characteristics reduce impact transfer between leaf spring packs and axles. This smooths the ride, reduces stress on hangers and u-bolts, and improves stability over rough, washboard surfaces common on many Utah backroads.
Brands: MORryde and Dexter offer well-regarded suspension components designed for trailers and RVs.
Hanger braces that run side-to-side
Why: Hanger braces that span side-to-side provide lateral rigidity and spread loads across the frame, preventing hanger twisting and reducing the chance of hanger failure. This is especially important when towing on rough or off-pavement routes to trailheads, campsites, or fishing lakes.
9/16" U-bolt kits instead of 1/2"
Why: Upgrading from 1/2" to 9/16" U-bolts increases clamping strength and fatigue resistance. Larger U-bolts reduce the likelihood of stretching, cracking, or failure under heavy loads or repeated flexing.
Complement: Use high-strength grade hardware and proper torque specifications; pairing with hanger braces and beefier spring packs completes the stronger suspension package.
Brand-name components to trust
MORryde: Known for vibration-absorbing products, equalizers, and robust trailer suspension upgrades that improve ride quality and durability.
Lippert: Offers many RV and trailer parts including upgraded suspension components, brackets, and accessories for longevity and fitment.
Dexter: A go-to for axles, brakes, and suspension components with strong aftermarket support and replacement parts.
Hercules Tire: A trailer tire brand that provides trailer-specific tires with appropriate load ratings and construction for hauling heavy loads over long distances.
Local Utah uses and why upgrades matter here
Escaping the heat: Many families from St. George and surrounding areas use travel trailers to escape low-elevation summer heat, heading to higher-elevation sites like Brian Head, Duck Creek, or the Pine Valley Mountains. Upgraded suspension and tires make mountain drives safer and more comfortable.
