OBS Chevy Long-Travel Suspension: What It Really Takes

Updated September 7, 2026

The short answer: long-travel is the hard part of an OBS Chevy prerunner build. The 2WD C1500 uses a coil-spring independent front end (the 4WD K1500 uses torsion bars), and unlike a Tacoma or Ranger, none of the major desert-suspension brands makes a long-travel kit for the 1988–1998 GMT400. You are not stuck with pure custom fab, though — OBS specialists do sell catalog long-travel kits, starting around $3,600.

The OBS front end: coil (2WD) vs torsion bar (4WD)

Both drivetrains use an independent, unequal-length A-arm (short-long arm) front suspension — the difference is the spring. The 2WD C1500 is sprung by coil springs; the 4WD K1500 is sprung by torsion bars. The 2WD is the usual prerunner starting point: it’s lighter, cheaper, rear-drive, and its independent front is well suited to building travel — not a solid axle you’d have to design around.

Why the major brands skip the OBS — and who actually sells a kit

The big desert-suspension brands simply skip this platform. Camburg starts its Chevy/GMC 1500 long-travel kits at 1999–2006; Dirt King starts at 2007. That leaves the 88–98 GMT400 as a fabrication platform. There was historically a Fabtech long-travel kit for the 88–98 C1500, but it’s long discontinued.

What fills the gap is the OBS specialists. Schumacher Metal Works (Nuevo, CA) sells 88–98 long-travel as catalog parts with published prices: a Basic 2WD Long Travel Kit at $3,600, a 4×4 Basic Long Travel at $4,500, an 88-98 Hybrid Long Travel Kit at $6,050 and a full Pre-runner Kit at $7,700 — plus 2WD and 4×4 coil-over conversions and Delrin or heim upper arms. LSK Suspension also lists an 89–98 C1500 2WD builders kit. Prices as listed September 2026. So the honest picture is narrower than “no kit exists”: the big brands skip this platform, a handful of specialists don’t.

What a custom OBS long-travel setup takes

A serious desert front end on an OBS is built, not bought:

  • Custom tubular upper and lower control arms, usually with 1" uniballs, for the extra width and travel.
  • Custom or modified spindles/knuckles to correct geometry.
  • A coilover conversion with quality shocks — see our King Shocks guide and the bypass vs coilover breakdown.

Street-truck tubular arms and drop/lift spindles exist in abundance for the OBS, but most are lowering- or lift-oriented, not desert long-travel — they’re a starting point, not a finished prerunner front end. Lean on a good fab shop. For the general theory, read long-travel suspension explained.

Rear suspension

The OBS leaves the factory with a leaf-spring live axle. Two paths:

  • Keep the leaves and add travel and control — longer shackles, an add-a-leaf, good bump stops, and quality shocks or bypasses. The simple, budget path.
  • Convert to link + coilover for a real desert rear. Bolt-on OBS coilover/4-link kits exist (Belltech, RideTech), but note those are marketed for street performance and handling, not desert racing — a hard-use desert rear still leans custom.

OBS long-travel FAQ

Does anyone make a bolt-on long-travel kit for an OBS Chevy?

Yes — just not from the major desert brands. Camburg starts at 1999 and Dirt King at 2007, but Schumacher Metal Works sells catalog 88–98 long-travel kits from $3,600 (basic 2WD) up to $7,700 (full pre-runner kit). Custom fab is one route, not the only one.

Is the OBS front suspension coil or torsion bar?

The 2WD C1500 uses coil springs; the 4WD K1500 uses torsion bars. Both are independent A-arm designs.

Is an OBS harder to build than a Tacoma or Ranger?

For long travel, yes — there’s no off-the-shelf kit, so budget for fab work. That’s the tradeoff for cheap V8 power and the classic OBS look.
