Long-Travel Coilover Conversion — Power Wagon (L7 / Race-Prep)

The end-state Power Wagon lift: a coilover conversion that replaces the factory coil-and-shock front suspension on the solid axle. A long-arm or fabricated 4-link kit, King 3.0 coilovers, frame brackets welded in, 12-14" of front travel. $15-24k done. This is race-prep — not for normal trail use, not for daily driving (mostly).

Long-travel coilover conversions replace the Power Wagon's entire factory front suspension with race-prep hardware:

Cost reality:

Total realistic build: $25,000-35,000 above the truck itself.

Long-arm vs. 4-link — both work on the solid axle. A long-arm coilover conversion (Carli, Thuren, Kore) keeps the axle located with longer control arms, is the more common and better-documented Power Wagon path, and bolts up more predictably. A fabricated 4-link is fully custom, lets a shop tune anti-squat and roll center, and is shop-built to the truck. Note that the "long-travel" Camburg and Total Chaos kits you see advertised are IFS-truck parts (Tacoma, 4Runner, half-ton) and do not fit the Power Wagon's solid front axle.

On-road behavior: With proper tuning (King 3.0 valving + bumpstop setup), a long-travel Power Wagon can be tolerable on highway, but the steering can feel different after the caster and track-bar geometry change, and the ride is firmer than a Carli or AEV setup. It's a race truck that you drive on the road, not a road truck with race capability.

Honest framing: if you have to ask whether you need long-travel, you don't. The AEV DualSport 4.5" (pw-lift-aev-dualsport) covers 95% of off-road use cases at a third of the cost. This entry exists for completeness; consider it the upper bound of what's possible.

This is not a bolt-in kit, and treating it like one is how people end up with a truck that handles worse than stock. The work, in order:

  1. Strip the factory front suspension — coil springs, shocks, control arms, sway bar, and often the factory bump-stop pockets come out entirely.
  2. Weld in the frame brackets — the coilover upper mounts tie into the frame with welded gussets. This step demands a jig (or a fixture built from the kit's templates) so left and right are mirror-identical; a few millimeters of bracket misplacement changes alignment and shock angle on that corner.
  3. Hang the new arms and coilovers — the long control arms (or fabricated 4-link) and the King or Fox 3.0 coilovers, then set ride height by spring preload.
  4. Tune the bump-stops — hydraulic or progressive stops are matched to the available up-travel so the tire never contacts sheet metal at full compression. Getting this wrong cuts travel or punches the tire into the fender.
  5. Align and shake down — a specialty alignment, then a deliberate low-speed then mid-speed shakedown to re-check every fastener and the coilover valving before any high-speed running.

Because the geometry is custom, a re-gear and a fender/tire plan (pw-lift-aev-dualsport covers the milder path) are part of the same project, not afterthoughts.

The failure modes here are expensive. Welding frame brackets at home without a jig is the most common one — a corner that sits a few degrees off throws caster and camber out of range that no alignment can recover, and the fix is cutting the bracket back off. Steering feel gets slower with the longer arms, which is normal; harsh on-road ride usually means the bump-stops or coilover valving were never tuned for street use, not that the kit is wrong. And the resale math is unforgiving: a buyer who wants a stock-ish Power Wagon will not pay for a welded-in race front end, so build this for yourself, not for the next owner.
