CircuitWorx axles withstand extreme drive train forces because the entire axle, including the tripod, is manufactured from solid billet. CircuitWorx axles are CNC precision machined, heat treated to our specifications, and shot peened to provide you with the most durable axle on the market today.

New billet steel pivot mount kits mate to your original control arms to relocate them further outboard moving the top of the tire out for up to 2° additional positive camber. Polyurethane bushings improve cornering and acceleration. Kits include all necessary hardware.

CircuitWorx Drag Spools are extremely durable, CNC machined from high strength billet steel, they feature precision ground bearing journals and offer a 35% reduction in rotating weight. Drag Spools help eliminate ?Peg Leg? starts and they distribute power smoothly and evenly. Drag Spools are available for most Integra, Prelude and Accord transmissions.

CircuitWorx Oil Pump gears are precision machined and ground out of solid steel to insure longer life than inferior quality sintered metal OEM gears. There are many factors that contribute to oil pump failure. Among them are contaminants in the oil, improper installation, unbalanced rotating assembly, etc. Since the pump is mounted to the front of the crank, the crank, rods, pistons and the flywheel/clutch assembly must be precisely balanced. If the assembly is even slightly out of balance, the oil pump gear is going to take a serious beating. A CircuitWorx billet oil pump gear is much stronger than a stock gear and will withstand high RPM vibration much better than a stock unit.
A CircuitWorx Oil Pump Gear is truly cost effective if you want to protect the investment you’ve made in your engine.
Oil Pump Gear FAQ

CircuitWorx has been manufacturing Final Drive sets for Honda drag racing applications* for over a decade**. Huge Horsepower and Drag Racing Slicks place tremendous loads on stock gear sets, quickly braking brittle carburized factory teeth. To combat this problem, CircuitWorx engineered replacement Final Drives featuring unique ratios with custom enlarged tooth profiles for extra load carrying capacities. Created from Aircraft Alloys and Heat Treated to custom specs, our Final Drives are tough, flexible and can absorb tremendous loads where others will quickly fail. CircuitWorx manufactures Final Drives for B, H and K series motors, in ratios ranging from 4.4, 4.6 and 4.7.
