In-house micro-polishing, shot peening, machining, and welding services.
Shot peening blasts the gear surface with small, round media, toughening the metal to resist cracks and fatigue under high power.
Gear detailing removes sharp edges, burrs, and rough spots so teeth mesh smoother with less heat and wear.
Together, they help your transmission handle more power and last longer.
Every engagement tooth, sleeve taper, and thrust clearance is dialed in individually on the shop bench to eliminate transmission lockouts.
We test on dynos, drag strips, and road courses. Only genuine parts and verified gear geometries make it into our final builds.
At Team Rip Engineering, specs and results are never estimated or rounded for sales talk. Turnaround times, core charges, and horsepower capabilities are built on real shop data and racing verification. If you have custom power goals or specialized gear ratio requirements, consult our technicians directly.
This replaces the phone call, the itemized list you used to email, and the paper tag. When you submit, you get a tag number, the ship-to address and a job page you can check any time.
Once submitted, print your generated TRE Digital Tag or write the Tag Number visibly on your shipment crate. Our techs match it immediately at the receiving dock.
Drain all gear oil thoroughly before crating. Un-drained fluids incur carrier hazardous fines. Bolt units firmly to the crate base.
