Mike Losh shocked us all when he built his ’67 C-10 and debuted it at SEMA a little while back. What took us all by surprise was the attention to detail that Mike lavished on the truck. It wasn’t just a completely finished, pavement-pounding ride, it also had a vintage theme that ran from top to bottom. Like truck builds are for so many others, the C-10 was a labor of love. The truck started as a mild project that snowballed, eventually taking nine years to complete, hence the name Cloud 9.
The truck was a huge success and it did well promoting Mike’s new venture making fiberglass inner fenders with clearance for airbagged 1967-72 C-10s. Cloud 9 combined with the Slosh Tubz product has definitely been a game changer in the scene. Mike was on a roll, and he knew he had to do something else to continue to support his business.
MIKE STARTED BY BORROWING SHOP SPACE AT STREET DRIVEN CUSTOMS IN BENTONVILLE, ARKANSAS AND TORE THE TRUCK DOWN TO BARE BONES.”



As the buzz grew about Slosh Tubz, Mike decided to expand the product line to cover 1973-87 C-10s. His mind was set to invest in the next best thing, and he started developing a plan to find a good starting vehicle. His wife Sarah suggested an SUV of the same body style, instead of another truck with limited seating.
Wasting no time, Mike called up good friend Tuffy Barnes, who happens to be a repo man about finding SUVs of desired eras. Two days after returning from SEMA with Cloud 9, Mike and Sarah were the new owners of this ’87 GMC Jimmy 4×4, Square Peg.
Mike’s actually been building vehicles for the majority of his life. He and his grandfather James Harrison wrenched together when Mike was young. With years of experience under his belt and one top-notch truck finished, Mike was ready to dig into the classic SUV.


Mike started by borrowing shop space at Street Driven Customs in Bentonville, Arkansas, where he tore the truck down to bare bones. With the factory frame stripped of the original suspension, a Scott’s Hotrods Super Slam independent front was put in place to convert the truck to two-wheel drive. This new IFS system not only updated the chassis, but it also allowed for the use of Slam Specialties RE-7 airbags to set the truck directly on the pavement. The front was upgraded with Scott’s Hotrods torsion-style sway bar and Classic Performance Parts SOS 73-87 dropped spindles and big brake kit.


Starting fresh in the rear, a new frame from the firewall back was made out of 2×4-inch steel. Letting the rear of the Jimmy sit down is a Scott’s Hotrods Super Slam parallel 4-link with pan hard bar used in combination with Ridetech F9100 airbags. To help tuck in the rear wheels, the rearend was narrowed a total of 5 inches before receiving an Auburn Gear posi, 4.11:1 gears and Moser axles. The entire suspension was upgraded with Energy Suspension bushings and QA1 Street Star billet adjustable shocks. The entire chassis was smoothed and painted by Gary Angel of Street Driven Customs, while an AccuAir air management system was added to control height adjustments.


Powering the Jimmy is a 5.3L Chevy LS engine that has a Camaro intake and oil pan. It was modernized with an MSD LS Atomic Injection system but has a retro look with the custom coil covers. With help from Gary Angel, these were made by taking two valve covers from ’50s inline- six engines and sectioning them down to fit. The engine was also upgraded with an Eddie Motorsports S-Drive serpentine system for form and function. Clean air comes in from a K&N filter and spent gases exit through a Hooker ceramic titanium-coated exhaust manifold connected to a custom Flowmaster exhaust built by Mike and Gary that uses two HP2 mufflers. Keeping the engine cool is a custom-made aluminum radiator with dual electric fans from Flex-a-lite. Behind the power plant is a 4l60E transmission that has a Painless Performance Products Perfect Torc transmission controller. A CPP slip-joint two-piece driveshaft links the transmission to the rearend.



Like with Cloud 9, Square Peg’s body was taken back to look like the vehicle just rolled off the factory lot. With help from LMC Truck, many of the glass pieces were replaced, along with the side trim and tailgate band. Then the body was painted by Kyle Gambrel of Laid Back Recreations in ’60s Volkswagen Turquoise created with BASF paint and chosen by Sarah. To finish it off, a set of bumpers, miscellaneous glass, latches and other pieces were obtained through Classic Parts of America. Finishing the look on the outside is a set of one-off 22-inch Budnik wheels designed to look like a “square peg.” Then they were wrapped in Atturo AZ800 tires.

When it came time to attack the interior, Mike knew he had to do something special because this SUV has more inside space than a truck of the same body style. Starting up front, Mike and Chip Fredrick fit a 1962 C-10 dash that was widened 3 inches and extended down by 4 inches. The dash was shaved a bit and a Dakota Digital VHX gauge cluster and AC controls that dictate the Vintage Air Magnum AC unit were added. Underneath is an ididit tilt steering column with firewall mount and Budnik billet steering wheel. Stitch Rod and Trim then stepped in to finish the interior, including a custom center console that houses the AccuAir controller and the controller for the hidden Kicker audio system.

Continuing on to the seating arrangements, Mike decided to implement a set of bucket seats from a 2009 Honda Accord. Beside them is a pair of heavily modified Rod Doors door panels. The custom-made rear seats were built into the raised rear floor structure. Under the Bed Wood and Parts canary wood false floor lies a Kinetik battery, two Kicker 10-inch subwoofers, air tanks and AccuAir VU-4 valve body for the air ride suspension. After the interior was configured, Laid Back Recreations applied Lizard Skin spray-on insulation, and then some Stinger Roadkill sound deadener was applied. Stitch Rod and Trim covered everything in tan leather with a few strategically placed plaid inserts.

Once completed, this Jimmy made big waves in the truck scene and has furthered the popularity of Slosh Tubz. The Losh family has definitely established themselves as more than able to create jaw-dropping rides. Word is that they’ve already started on their next big project, and we’re sure that it’s on its way to being another hit. Until then, we’ll just have to settle for gawking at this stunning Jimmy. ST
