Weighing 4g per set, these gears reduce axle speed by about 11% compared to stock, and use a worm drive design for increased ground clearance. They are a direct fit for the entire SCX24 lineup, including the C10, JLU, Gladiator, Bronco, and Deadbolt models.\u003c\/p\u003e\u003ch2\u003eHow these gears change your SCX24's performance\u003c\/h2\u003e\u003cp\u003eInstalling the 18T underdrive gears slows the axle rotation relative to the driveshaft. This gives you more torque at the wheels and finer throttle control on technical terrain. The worm gear setup—a worm screw and worm gear in each differential—raises the axle tube, boosting ground clearance over stock components. The etched tooth count on the pinion gear makes identification simple during installation.\u003c\/p\u003e\u003ch2\u003eWhat's in the set and how to identify them\u003c\/h2\u003e\u003cp\u003eThis set includes four gear types: pinion, ring (worm), and associated parts. Each pinion has its tooth count etched into the metal for easy recognition. The total weight of the complete set is 4 grams, making them a lightweight but durable steel upgrade over plastic factory parts.\u003c\/p\u003e\u003ch2\u003eCompatibility with Axial SCX24 models\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAxial SCX24 C10\u003c\/li\u003e\n\u003cli\u003eJLU Jeep Wrangler\u003c\/li\u003e\n\u003cli\u003eGladiator JT\u003c\/li\u003e\n\u003cli\u003eFord Bronco\u003c\/li\u003e\n\u003cli\u003eDeadbolt\u003c\/li\u003e\n\u003cli\u003eOther SCX24-based trucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis gear set is designed specifically for the 1\/24 SCX24 platform.

The supplied note explains that using underdrive in the rear (or overdrive in front) makes the front axle pull faster than the rear. This helps the truck climb better and reduces the chance of tipping over backward. Because this set is an underdrive, using it on the rear axle (or keeping the front stock) creates that pulling effect. Experiment with front vs. rear placement to tune your truck's handling.\u003c\/p\u003e\u003ch2\u003eSpecifications at a glance\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eINJORA 18T Underdrive Worm Differential Gears (Steel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4g per set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTooth count identification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEtched on pinion gear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpeed reduction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eApprox. 11% underdrive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAxial SCX24 series (C10, JLU, Gladiator, Bronco, Deadbolt)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eCan I install these gears in any SCX24 model?\u003c\/h3\u003e\u003cp\u003eYes, they suit the entire SCX24 platform, including the C10, JLU, Gladiator, Bronco, and Deadbolt.\u003c\/p\u003e\u003ch3\u003eWhat is the exact weight of the gear set?\u003c\/h3\u003e\u003cp\u003eThe set weighs 4 grams.\u003c\/p\u003e\u003ch3\u003eHow does underdrive improve climbing?\u003c\/h3\u003e\u003cp\u003eUnderdrive in the rear (or overdrive in front) makes the front axle rotate faster, which pulls the truck forward on obstacles and reduces the risk of flipping backward.\u003c\/p\u003e\u003ch3\u003eAre these gears compatible with other differentials?\u003c\/h3\u003e\u003cp\u003eThe data provided does not specify compatibility beyond SCX24 models.
