White-knuckle driving, bouncing over expansion joints, and trailer sway don’t have to be part of RV life. Learning how to upgrade your RV suspension for better handling and ride quality can transform stability, braking, and comfort—whether you drive a motorhome or tow a travel trailer or fifth wheel.
Why RV Suspension Upgrades Matter
Your RV suspension does more than smooth the ride. It:
- Improves directional stability and steering feel (crucial in crosswinds or when semis pass).
- Reduces sway and porpoising, protecting cabinets, appliances, and cargo.
- Shortens stopping distances by keeping tires planted and weight properly distributed.
- Cuts driver fatigue, making long travel days safer and easier.
If you’re unsure where to start—or want a professional assessment of tires, axles, and bushings—schedule a suspension evaluation at Daisy RV.
Signs Your RV Suspension Needs Attention (or an Upgrade)
- Excessive body roll in turns or when changing lanes
- Sway from passing trucks or gusty winds
- Bounce or porpoising over dips/bridge joints
- Uneven or accelerated tire wear
- Clunks/creaks from worn bushings or shackles
- Visible leaf spring sag, cracked shackles, or leaking shocks
Any one of these is a solid reason to learn how to upgrade your RV suspension for better handling and ride quality—and fix issues before they become safety problems. Get a quick check at Daisy RV.
Towables: Travel Trailer & Fifth-Wheel Suspension Upgrades
Equalizers, Wet Bolts, and Heavy-Duty Shackles
Stock nylon bushings and thin shackles wear quickly. Upgrades include:
- Bronze bushings + wet bolts (greaseable) to reduce friction and extend life
- Heavy-duty shackles (thicker plates) to prevent elongation and failures
- Enhanced equalizers (e.g., rubber shear or cushioned equalizers) to absorb shock and reduce chucking
Result: quieter operation, less hobby-horse motion, and tighter tracking behind the tow vehicle.
Add Shocks to the Axles
Many trailers ship without shocks. Adding tuned gas shocks:
- Controls vertical wheel movement
- Protects cabinets and appliances from harsh impacts
- Reduces tire skipping and improves braking traction
Upgrade Leaf Springs or Add an Overload/Sumo-Style Helper
- Correct spring rate restores ride height and travel in the suspension
- Helper springs or microcellular jounce springs (e.g., Sumo-style) add progressive support without harshness
- Pair with the right equalizer for a balanced setup
Axle Alignment and Camber
Bent axles or misalignment chew tires fast. A competent shop can:
- Cold-bend axles to correct camber/toe
- Align axles to the kingpin/coupler centerline for straight tracking
Pin Box & Hitch Tuning (Fifth Wheels)
A rotational or cushioned pin box reduces chucking; a properly adjusted hitch height keeps the trailer level so both axles carry their share.
Motorhomes: Class A, B, and C Suspension Upgrades
Shocks: The Foundation of Control
Quality shocks tailored to your coach’s weight:
- Reduce porpoising and brake dive
- Improve rebound control over bumps and dips
- Keep tires in contact with the pavement for shorter stops
Sway Bars (Anti-Roll Bars)
Heavier, adjustable sway bars:
- Cut body roll dramatically in crosswinds and on ramps
- Reduce driver correction and fatigue
- Work front and rear; many coaches benefit most from a rear bar upgrade first
Track Bars / Panhard Rods
For leaf-spring, solid-axle coaches:
- A rear track bar prevents side-to-side axle “walk” (tail-wag)
- Yields laser-straight highway tracking
Steering Stabilizers
A centered return-to-straight stabilizer helps:
- Dampen sudden gusts or pothole hits
- Reduce wander on crowned roads
- Ease tension on long days behind the wheel
Air Springs / Air-Assist
Supplementary air bellows:
- Level side-to-side and front-to-rear
- Fine-tune ride height and firmness for load and road conditions
- Especially helpful on heavier Class A/C rigs

Tires, Pressures, and Weights: The Hidden Suspension “Setting”
Even the best hardware fails if tire pressures or weights are off:
- Four-corner weigh your RV when loaded for travel.
- Inflate tires per the manufacturer load/inflation chart for your actual axle weights (not just max PSI).
- Keep tire speed reasonable; heat is suspension’s enemy.
- Verify tongue weight (10–15%) for travel trailers and pin weight (15–25%) for fifth wheels to tame sway and improve braking.
Installation Tips and Best Practices
- Replace components in systems, not piecemeal (e.g., equalizer + wet bolts + shackles together).
- Use torque specs and re-torque after 50–100 miles; suspension hardware seats in.
- Add zerk fittings access where possible; grease on a regular schedule.
- After shock or spring changes, re-check ride height and headlight aim.
- For motorhomes, re-center steering wheel after alignment and stabilizer install.
Maintenance Schedule After Upgrades
- Every trip: Visual check for leaks (shocks), loose hardware, bushing wear.
- Every 3–6 months: Grease wet bolts, inspect equalizers and shackles.
- Annually: Alignment check, tire wear analysis, torque audit of key fasteners.
- Before big trips: Bounce test, listen for new noises, and confirm pressures/weights.
Cost vs. Payoff: Where to Start for Maximum Impact
Towables (good → better → best):
- Wet bolts/HD shackles + cushioned equalizer
- Add tuned shocks
- Spring rate correction + axle alignment
Motorhomes (good → better → best):
- Premium shocks
- Rear sway bar + steering stabilizer
- Track bar + front sway bar, then air-assist if needed
Most owners report the single biggest transformation from shocks (all RVs) and rear sway/track bars (motorhomes), or equalizer + wet bolts (towables).
Troubleshooting After an Upgrade
- Still swaying? Check tongue/pin weight and tire pressures; verify hitch height/WDH tension.
- Porpoising remains? Consider higher-quality shocks or cushioned equalizer; inspect spring rates.
- Wander persists? Add/adjust steering stabilizer and rear track bar; confirm alignment and toe.
- Uneven tire wear? Re-weigh, correct ride height, and do a professional axle alignment.
