Denver’s Axle and Differential Specialists Since 1995

Colorado Axle and Gear is a third-generation, family-owned axle and differential repair shop located in Denver, Colorado. Owner Al Lovi and his team have been building a reputation for honest, expert-level axle and drivetrain work for over 30 years. More than 80 percent of our business comes from referrals — a testament to the quality of every repair that leaves our shop.

Our specialty is exactly what the name says: axles and differentials. We do not try to be a general repair shop. This focused expertise means we have seen virtually every axle and differential problem on every major platform, and we have the right tools, the right parts relationships, and the hands-on experience to do the job correctly the first time.

What We Do

Differentials: We repair, rebuild, and regear front and rear differentials on all major platforms. Whether you need a worn carrier bearing replaced, a complete ring and pinion swap for a regear, or a full differential rebuild after a failure, our shop handles it all. We work with Dana 30, Dana 44, Dana 60, Ford 8.8, GM 10-bolt and 12-bolt, AAM, and other common differentials.

Drive Axles and CV Joints: A worn or broken CV axle shaft or U-joint can leave you stranded. We replace drive axles, CV shafts, and U-joints on two-wheel drive, four-wheel drive, and AWD vehicles. We stock quality replacement shafts for most trucks and SUVs and can source heavy-duty aftermarket upgrades when factory shafts are not up to the job.

Gear Ratio Changes (Regearing): When you lift your Jeep, truck, or SUV and install larger tires, the factory gear ratios become mismatched, causing sluggish performance, poor fuel economy, and excessive strain on the drivetrain. We calculate the optimal gear ratio for your tire size and transmission, then install new ring and pinion gears to restore proper performance. Typical regear combinations include 4.56, 4.88, and 5.13 ratios for lifted rigs with 33- to 40-inch tires.

Locking Differentials: We install all major locking differential brands including ARB Air Lockers, Detroit Lockers, Eaton E-Lockers, and Spicer Trac-Lok limited-slip units. A locker is the single most effective traction upgrade for serious off-road use. We install them correctly and set them up to work reliably for years.

Pinion Angle Correction: After a lift, driveshaft vibration caused by incorrect pinion angle is a common problem. We diagnose and correct pinion angle to eliminate vibration and protect your U-joints from premature wear.

Free Diagnosis: We provide free, honest diagnoses on all axle and differential problems. No charge to inspect your vehicle and give you a clear, upfront estimate. No hidden fees.

We work with the top manufacturers in the industry: Dana/Spicer, Eaton, ARB, Detroit Locker, AAM (American Axle), Strange Engineering, Revolution Gear and Axle, and Yukon Gear and Axle.
