Suspension for washboard, frost heave and sand
The work here is long days on graded and ungraded forest road, followed by highway miles on pavement that has been through a freeze and thaw cycle. There are 13,494.1 miles of state forest road in the DNR inventory, and the surface varies from hard-pack to deep sand within a mile.
Ask a shop to set spring rates for the real loaded weight and to pick damping that holds up on hours of washboard. Ride height is a smaller question in a state where the high point is 1,979 feet and almost nothing needs articulation.
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.
How high is Michigan?
From Oscoda at 588 feet to Mount Arvon at 1,979.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.

Towns
WatersmeetWhere US 2 meets US 45 in the middle of the Ottawa National Forest. Nearest town to the Sylvania Wilderness and the forest’s highest ground.1,598 ft
IronwoodFar western corner on US 2, at the edge of the Ottawa National Forest. The Ottawa calls it the largest city on the forest boundary, at about 9,000 people. The Black River byway leaves from Bessemer just east.1,503 ft
CadillacSupervisor’s office town for the Huron-Manistee National Forests. The USGS puts the geographic center of Michigan in Wexford County, 5 miles north-northwest of here.1,308 ft
GraylingOn I-75 at the Au Sable River, with state forest road country in every direction and the Huron National Forest to the east.1,135 ft
BaldwinMiddle of the Manistee National Forest, on the Pere Marquette. Sections of the Michigan Cross Country Cycle Trail and the forest’s motorcycle trails run either side of town.837 ft
MarquetteThe largest city in the Upper Peninsula and its main stop for parts, tires and a hospital. Commercial flights serve it, and Munising is about 43 miles east.664 ft
HoughtonKeweenaw Peninsula service town on US 41, and the mainland headquarters for Isle Royale. The Ranger III sails from here and your vehicle stays behind.634 ft
Grand MaraisEast end of County Road H-58 and the Grand Sable Visitor Center. The road east of Adams Trail is not plowed in winter, so this end goes quiet.628 ft
Copper HarborNorth end of US 41 and of the Copper Country Trail byway, 52 miles from Houghton by the Park Service’s reckoning. The other Isle Royale ferry leaves from here.615 ft
Sault Ste. MarieBorder city at the east end of the Upper Peninsula and the start of the Whitefish Bay byway south on the Mackinac Trail, H-63.613 ft
OntonagonOn Lake Superior about 20 miles east of Porcupine Mountains Wilderness State Park, per the DNR. Last real services before the park’s campgrounds and the South Boundary Road.613 ft
MunisingWest gateway to Pictured Rocks and the Hiawatha’s Munising Ranger District. The Grand Island ferry leaves from M-28 about 2.5 miles west of town.607 ft
ManistiqueOn US 2 on the Lake Michigan shore, in the Hiawatha’s Rapid River and Manistique district. Forest Road access to the single rustic lake campsites runs north on M-94.600 ft
Traverse CityLargest town in the northwest Lower Peninsula, on the M-22 byway and about an hour from Sleeping Bear Dunes. Full services before the smaller lakeshore towns.596 ft
St. IgnaceNorth end of the Mackinac Bridge, where I-75, US 2 and M-134 meet. The place to wait out a wind closure rather than sit on the approach.590 ft
OscodaLake Huron end of the River Road National Scenic Byway, where the Au Sable reaches the lake. Eastern gateway to the Huron National Forest.588 ft
Passes, high roads and summits
Mount ArvonThe highest point in Michigan, in Baraga County. Our own reading of the USGS elevation surface at the summit is 1,978 feet1,979 ft
Mount CurwoodA few miles from Arvon and within two feet of it on our reading. The USGS names Arvon as the state high point1,977 ft
Summit PeakHigh ground of Porcupine Mountains Wilderness State Park. Our own reading, because no state page publishes an elevation for it1,956 ft
Pass, road and summit elevations are the figures published by the agency that manages them. Town elevations are the town’s or county’s own
figure where it publishes an exact one; the rest are from the U.S. Geological Survey (3D Elevation Program at the place’s official coordinates),
