Standard bump stops mount directly under the lower control arm, which creates an inefficient leverage geometry that forces you to choose between a firm ride that handles big hits or a soft ride that bottoms easily through smaller stuff. The slapper arm design changes that equation by positioning the bump stop strike point further outboard on the lower arm, maintaining a consistent motion ratio through the full bump travel zone. The result is a suspension that stays active and plush through the ride range and only engages the bump stop progressively as the wheel approaches full compression. No wallowing, no bottoming, no abrupt transitions.\u003c\/p\u003e\n\u003cp\u003eEach slapper arm is CNC machined from 6061 billet aluminum and Type III hard anodized black. The arms pivot on bearing bronze bushings and are mounted using aircraft AN bolts that match the grip and shoulder length needed for proper joint strength under off-road loads. The Camburg KINETIK 2.5x2-inch bump stops are included and function more like an air shock than a traditional rubber stop, building resistance progressively rather than hitting a hard wall. A custom rubber pad on the slapper arm contact surface reduces noise on contact. Bump stop mounts come raw (unfinished) and need to be welded to the chassis. Camburg recommends spraying with black Steel-IT after welding for corrosion protection.\u003c\/p\u003e\n\n\u003ch4\u003eCAM-110246-4 Key Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlapper arm design: strike point is further outboard on the lower arm for consistent motion ratio and better bump stop efficiency\u003c\/li\u003e\n  \u003cli\u003eCamburg KINETIK 2.5x2-inch slapper bump stops included: progressive resistance, not a hard stop\u003c\/li\u003e\n  \u003cli\u003eCNC machined slapper arms from 6061 billet aluminum, Type III hard anodized black\u003c\/li\u003e\n  \u003cli\u003eBearing bronze pivot bushings for smooth, durable arm articulation\u003c\/li\u003e\n  \u003cli\u003eCustom rubber contact pad on arm reduces impact noise\u003c\/li\u003e\n  \u003cli\u003eAircraft AN hardware (proper grip and shoulder length for maximum strength)\u003c\/li\u003e\n  \u003cli\u003eDriver-side and passenger-side upper mounts included\u003c\/li\u003e\n  \u003cli\u003eMounts come raw for welding to chassis (Camburg recommends Steel-IT coating after welding)\u003c\/li\u003e\n  \u003cli\u003ePairs with Camburg long-travel kit (CAM-110246 series) for complete front suspension build\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eProduct Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003eCAM-110246-4\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eCamburg Engineering\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eKit Type\u003c\/td\u003e\n\u003ctd\u003eFront Slapper Bump Stop Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBump Stop Size\u003c\/td\u003e\n\u003ctd\u003e2.5 x 2 inch (KINETIK Series)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArm Material\u003c\/td\u003e\n\u003ctd\u003e6061 Billet Aluminum, CNC machined\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArm Finish\u003c\/td\u003e\n\u003ctd\u003eType III Hard Anodized Black\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArm Pivot\u003c\/td\u003e\n\u003ctd\u003eBearing bronze bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHardware\u003c\/td\u003e\n\u003ctd\u003eAircraft AN bolts, proper grip\/shoulder length\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMounts\u003c\/td\u003e\n\u003ctd\u003eRaw (require welding; recommend Steel-IT coating after)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003eFront\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003e2021-2025 Ford Bronco (Long-Travel builds)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eVerify with supplier\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProp 65\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eWhat Is Included\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2x CNC billet slapper arms (driver and passenger, black anodized)\u003c\/li\u003e\n  \u003cli\u003e2x Camburg KINETIK 2.5x2-inch slapper bump stops\u003c\/li\u003e\n  \u003cli\u003e1x Driver-side upper mount (raw, requires welding)\u003c\/li\u003e\n  \u003cli\u003e1x Passenger-side upper mount (raw, requires welding)\u003c\/li\u003e\n  \u003cli\u003eAircraft AN hardware kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCoilovers, long-travel lower arms, and upper control arms are sold separately.

The slapper arm keeps the contact point further outboard and maintains a more consistent motion ratio, so the bump stop works predictably across the full travel range rather than spiking hard at a single point.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do the mounts require welding?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes. The upper bump stop mounts in the CAM-110246-4 kit are supplied raw and must be welded to the chassis. This is a professional fabrication step. Camburg recommends coating the welded mounts with black Steel-IT spray after welding for corrosion protection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Will this kit work on a stock-height Bronco?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: This kit is designed for use with Camburg long-travel suspension builds. It is not intended for stock-height Broncos and requires the Camburg long-travel lower control arms (CAM-110246 series) for correct geometry and mounting position.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What makes the KINETIK 2.5 bump stops different from rubber stops?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The Camburg KINETIK 2.5 x 2 slapper bump stops use a progressive resistance design that builds force gradually as the suspension compresses, similar to an air shock. Traditional rubber bump stops hit hard and abruptly. The progressive design allows a more comfortable ride in the normal suspension range while still providing firm bottoming resistance when needed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I run this kit with Bronco Raptor upper control arms?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes. The CAM-110246-4 slapper bump stop kit pairs directly with the Camburg Bronco Raptor upper control arms (CAM-110257-GRY) for a complete front suspension upgrade.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the warranty on the Camburg CAM-110246-4?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Camburg Engineering covers their products under a standard limited manufacturer warranty against defects in materials and workmanship.
