AXLE & DRIVELINE
Re-gears, lockers, axle upgrades, and driveline correction for lifted and big-tire 4x4s, planned so the drivetrain better matches the rest of the vehicle.
Drivetrain work that restores the balance
Larger tires change effective gear ratio, axle load, driveline angles, and the strain placed on Ujoints. We handle the gear, locker, axle, and driveline work that helps the vehicle feel more appropriate for its current setup.
Gear setups are done by hand with proper pattern checks, backlash spec, and pre-load torque. Lockers are installed with the correct carriers, side gears, and bearings. Driveline corrections account for lift height, suspension cycle, and pinion angle — not just bolt-on length changes.
Driveline work we handle
Ring & Pinion Re-Gears
Gear ratio changes matched to your tire size, transmission, and use case — dialed in by hand to spec.
Locker Installation
Selectable air and electric lockers, automatic lockers, and limited-slip differentials — front and rear.
Axle Shaft Upgrades
Chromoly and high-strength axle shaft upgrades for big tires, locked diffs, and serious wheeling.
U-Joint & CV Service
Heavy-duty U-joints, CV joints, and full driveshaft service for lifted geometry.
Driveshaft Lengthening & SYE
Driveshaft lengthening, slip-yoke eliminators, and CV-style driveshafts to correct lift-induced angles.
Transfer Case Work
Transfer case redos, t-case drops, low-range gear sets, and twin-stick conversions.
Pinion & Driveline Angle Correction
Adjustable control arms and pinion shims to dial pinion angle and eliminate driveline vibration.
Fluid, Bearing & Seal Service
Diff service, axle bearing replacement, pinion seals, and full fluid changes on synthetic intervals.
Re-geared, locked, and ready for the load
Bigger tires change the math on the whole drivetrain. We review ring-and-pinion ratios, locker options, axle support, and driveshaft angles so the system better suits the tire size and the way the vehicle is used.
What proper driveline work delivers
A capable rig that doesn't have the drivetrain to back it up is a future repair bill. Doing the work right means it actually performs and lasts.
- Restored effective gear ratio so the engine and transmission aren't fighting big tires
- Better fuel economy and throttle response on the highway after a re-gear
- Traction in low-traction situations from properly installed lockers
- Axle shafts and U-joints that hold up under locked-diff, big-tire load
- Eliminated driveline vibration from corrected pinion and driveshaft geometry
- Service intervals tracked so wear is caught before failure
Platforms we re-gear & service drivetrains for
Re-gear services are currently offered on Jeep platforms only. All other driveline services — axle shafts, U-joints, driveshaft upgrades, pinion angle correction, and fluid service — are available for every platform listed below.

Why owners bring drivetrain work here
Hand-set gears
Pattern checked, backlash measured, pre-load torqued. Not air-gun installed and hoped for.
Right ratios for your project
We pick gears based on your tire size, transmission, and how you actually drive — not a generic chart.
Lockers matched to use case
Selectable, automatic, or limited-slip — chosen based on terrain and daily-driver tradeoffs.
Driveline geometry corrected
We fix pinion angle and driveshaft phasing — not just throw a longer shaft at it.
Heavy-duty when it matters
Chromoly shafts, HD U-joints, and proper carriers when the project justifies them.
Documented setup specs
Ratios, backlash, and torque values recorded so future service has a reference.
Drivetrain problems we resolve
When the vehicle feels gutless, vibrates, or chews drivetrain parts after a lift or tire upgrade, the cause is almost always one of these.
- Sluggish acceleration and harsh transmission shifts after a tire size jump
- Highway vibration that gets worse with speed after a lift
- Broken U-joints on big-tire Wranglers and Tacomas after wheeling
- Twisted or snapped factory axle shafts on locked rigs
- Diff whine from worn bearings or a poorly installed gear set
- Pinion seal leaks after deep water crossings
- Slip-yoke driveshaft binding on lifted JK Wranglers
- Transfer case noise from low fluid or worn chain on high-mileage rigs
Driveline work serving Tampa Bay 4x4 owners
Customers bring Jeep Wranglers and Gladiators in from Tampa, Wesley Chapel, and Hillsborough County for re-gears and locker installs, and Toyota, Ford, and full-size truck owners come in from Trinity, Odessa, Land O' Lakes, Tarpon Springs, and Palm Harbor for axle, U-joint, and driveshaft work. Gear setups are done by hand on every platform, with documented backlash and pattern checks.
