Specialty Services

We do offer basic customization services, but we’re also better than that. We specialize in making vehicles bigger, faster and flashier. To get an idea, here are a few of our services…

Suspension Lifting, Leveling & Lowering Installation:

Known for our big trucks, we install 30-50 lift kits annually – but we don’t stop there. We level and lift cars and trucks too. Our experience with body kits makes us experts, knowing how to address the specific needs to lift, level or lower your vehicle.

Intake & Exhaust

A new intake and exhaust system is a common step to take your vehicle’s performance to the next level. We do custom and bolt-on intake and exhaust installation, and we will help you pick the right system.

Performance Chips & Programmer Installation:

For those who want to unleash the full potential of their vehicle, a new performance chip will improve engine performance and gas mileage. We can also help with the different aftercare each performance chip requires.
