What we do

Services

From OE replacement parts to aftermarket performance products and full custom work. Every job is quoted up front, so you know the cost before a wrench moves.

01

Performance

LS, LT, Hemi & Coyote

LS and LT platforms are the core of the shop, with Hemi and Coyote builds running alongside them. Cars, trucks and SUVs, from a first set of bolt-ons through to a complete engine swap built around the way you actually drive the vehicle.

You get told what is worth doing and what is not. If a part will not earn its money on your build, we say so before you buy it instead of after.

What that covers

  • LS and LT performance for cars, trucks and SUVs
  • Hemi and Coyote performance builds
  • Complete engine swaps and full vehicle conversions
  • Every job quoted up front, before the work starts

02

Drivetrain

Ring & Pinion Packages and Axles

Ring and pinion packages, axle shafts, and full axle upgrades or swaps. When the engine makes more than the factory driveline was built for, this is the part that has to catch up.

Gearing gets matched to the tire size and the way the vehicle is actually used, so it drives properly on the road instead of only looking right on paper.

03

Suspension

Suspension, Steering & Brakes

Leveling kits, lift kits and lowering kits, plus custom suspension fabrication when an off the shelf kit will not do it. Trucks and SUVs are most of this work, and a 2025 Nissan Frontier Pro4X lift is a recent example.

Steering and brake upgrades go with it. More power usually means the brakes and the steering have to keep up, and that is the part people skip. We fit packages from Old Man Emu, Fox, Bilstein, PowerStop, Wilwood and Brembo.

04

Accessories

Wheels, Tires & Accessories

Tires and wheels, bumpers, tonneau covers, steps and lights, sourced and installed at the shop. If the truck is getting a lift or leveling kit at the same time, the wheels, tires and bumpers get picked to suit the new stance, so it all fits the first time.

We carry lines like Fuel Off-Road, Method Race Wheels, Westin, AMP Research and N-Fab, plus tires from BFGoodrich, Nitto, Toyo and Mickey Thompson. If you want something that is not on the list, send us the part number and we will price it.

05

In house

Metalwork & Fabrication

Custom fabrication, welding, exhaust fabrication and CNC plasma cutting, all done in house, along with complete custom C10 frame swaps, C-notches and other frame work. Frame jobs are measured and built here for the vehicle in front of us, not sent out to a third shop and returned on somebody else's schedule.

A lot of people end up here because they could not find a shop willing to take on anything out of the ordinary. If the part you need does not exist, it gets made. That runs well past the automotive world, down to in-ground goose and duck hunting pits.

06

Workshop

Diagnostics & Repair

Diagnostics, repair and engine rebuilds, on modern vehicles and classics. The first job is working out what is actually wrong, not selling you the biggest repair on the list.

A 2011 Tahoe came in with a lifter tick after other shops quoted $8,000 to $12,000 to fix it with a whole new engine. It did not need one.

What that covers

  • Diagnostics on driveability and engine faults
  • Repair work on modern and classic vehicles
  • Engine rebuilds
  • A second opinion before you pay for a new engine

How a job runs

Three steps, no guesswork

01

Tell us the vehicle and what you want

Call or email with the year, make and model, and what you are trying to get out of it. A rough idea is enough to start.

02

Get a straight answer on cost and time

The job gets quoted up front. Flat rate on some work, hourly on the bigger projects. If part of it is not worth doing, you hear that too.

03

Book the work

Pick a date that suits you. The shop is out on Weld County Road 64 east of Greeley, so call ahead before you make the drive.
