Suspension for washboard and a heavy load
The work here is hundreds of continuous miles of gravel at a steady speed, with a vehicle loaded for a week of self-sufficiency and carrying two full-size spares. That is a damping problem before it is a lift problem. The BLM describes the Dalton as narrow, with soft shoulders, high embankments and steep hills, and long stretches of sharp rock, potholes and washboard; the Denali Highway caps the recommended speed at 35 miles per hour for the same reasons. Set spring rates for the real finished weight, and tell the shop the surface is gravel, not rock.
A suspension shop matches spring rates and shock valving to the vehicle's real loaded weight, corrects the geometry that a lift changes, and aligns it afterward. On an overland vehicle the goal is control and durability under constant load, not maximum height.
The work usually includes
01Coil and leaf springs rated for the load
02Shocks: monotube, remote reservoir or adjustable
03Control arms, track bars, driveline and brake line corrections
04Air bags or helper springs for heavy rear loads
05Alignment after the work
06Advice on gearing when tire size goes up
How to choose a suspension shop
The right shop asks about weight before it asks about height.
01Weigh the vehicle loaded, or ask the shop to. Choosing springs without a weight is a guess.
02Ask what else the lift changes on your platform: alignment range, driveline angles, brake lines, headlight aim and driver-assistance sensors.
03Ask whether they align in house.
04Ask for the least height that clears your tires and keeps the geometry happy. More lift is not better.
05Ask how it will ride at both ends of your use: empty around town and loaded on washboard.
What to have ready before you ask for a quote
Weight is the number that matters.
01Year, model and drivetrain
02Current tire size and the size you want to run
03Everything bolted on: bumper, winch, rack, tent, drawers, water
04Loaded weight, if you have been across a scale
05How you use it, and a budget range
Questions people ask
How much lift do I need?
Less than you think. Most overland travel is dirt roads, washboard and the occasional ledge, and the vehicle spends its life loaded. Enough lift to clear a sensible all-terrain tire, with springs rated for your weight, usually drives better and breaks less than a tall kit.
Why does my truck sag in the back?
Because the factory springs were chosen for an empty truck. Drawers, a fridge, water, a tent and a rear bumper add constant weight. The fix is springs rated for that constant load, sometimes with air bags for the occasional heavy trip.
Do bigger tires mean I need new gears?
Larger tires make the engine and transmission work harder and change the speedometer reading. Whether re-gearing is worth it depends on the tire size, the vehicle and how much weight you carry. A shop that knows your platform can tell you where the line is.

Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
