This 1991 GMC Syclone is one of approximately 3,000 examples built for a single model year and shows just over 21k miles. The truck was sold new at Tri County Auto Center of Pottstown, Pennsylvania in January 1992 before being moved to Michigan, where it was acquired by the seller in 2019. A turbocharged 4.3-liter V6 powers all four wheels via a four-speed automatic transmission and a Borg-Warner transfer case, and modifications include Corvette Z06-style wheels. A new heater core was reportedly installed and an inspection performed in July 2019. This Syclone is offered with a window sticker, factory literature and promotional materials, a GMC Certificate of Authenticity, service records, a clean Carfax report, and a clean Michigan title in the seller’s name.

The body is finished in black paint and features Syclone-specific cladding with red lettering. A black vinyl Extang snap-on tonneau cover was installed to replace the ripped factory piece, which is also included in the sale.

Black 18″ C6 Z06-style wheels with red accents have been fitted in place of the factory 16″ versions, which are included separately. Nankang Ultra Sport NS II tires show 2011 date codes.

The cabin is trimmed in gray cloth and features bucket seats and matching door panel inserts with red piping, Syclone-branded floor mats, a Delco cassette stereo with a graphic equalizer, and a leather-wrapped steering wheel. The air conditioning has been converted to R134A under the seller’s ownership.

Instrumentation includes a 120-mph speedometer, a tachometer with a 5,200-rpm redline, a factory boost gauge, and a six-digit odometer indicating just under 22k miles. The oil pressure gauge is inoperable and the windshield wipers are described as slow.

The 4.3-liter Vortec V6 featured a Mitsubishi TD06-17G turbocharger and a water-to-air intercooler from the factory, and was rated at 280 horsepower when new. A K&N air filter was installed under previous ownership, while a new heater core was fitted and a general inspection was performed in July 2019. The factory heater core will be included in the sale.

A 700R4 four-speed automatic transmission routes power to all wheels via a Borg-Warner transfer case with a 35/65 front/rear torque split. Additional underside photos are viewable in the gallery.

The framed window sticker lists standard and optional features as well as an MSRP of $26,120. Factory literature, promotional items, and a framed GMC Certificate of Authenticity are included in the sale.

The August 2019 Carfax report lists no accidents or other damage and shows history in Pennsylvania and Michigan from new through April 2019. Cold start and zero-to-60 videos are viewable below.
