The Bully BCOTW11 Outer Thrust Washer is engineered specifically to handle the aggressive axial loads generated by 11-tooth configurations. Standard washers simply lack the dimensional tolerance required to prevent clutch binding under heavy acceleration. By providing a hardened, precision-machined barrier between the snap ring and the clutch drum, this thrust washer ensures your clutch engages smoothly at the exact RPM you set, eliminating the erratic lock-ups that ruin lap times.\u003c\/p\u003e\u003ch2\u003eTuning Synergy: From Your Walbro Carburetor to the Drive-line\u003c\/h2\u003e\u003cp\u003eAchieving peak performance isn't just about fuel delivery; it's about how that power reaches the rear axle. You can spend hours dialing in the jetting on your walbro carburetor, but if your clutch is binding due to improper thrust clearance, that horsepower is wasted as heat. This 11-tooth specific washer maintains the critical float your Bully clutch needs, ensuring the power curve you tuned at the carb translates directly into forward bite out of the corner.\u003c\/p\u003e\u003ch2\u003eHeat Management: Protecting Your Clutch Like You Protect Exhaust Parts\u003c\/h2\u003e\u003cp\u003eFriction is the enemy of consistency.

The Bully Clutches .085\" Black Spring (MPN: 098-086) delivers a highly balanced tension rate specifically engineered for 6-spring clutch configurations. By providing a medium-stiff engagement profile, this spring allows the clutch shoes to slip optimally at lower RPMs before locking up precisely at peak torque. This translates to explosive corner exits and reduced bogging under heavy engine load. Whether you are running a high-horsepower modified clone or a standard Briggs animal, tuning your slip points with the .085\" black spring ensures your power band is maximized on every straightaway.\u003c\/p\u003e\u003ch2\u003eSynergy with Wheel Hub Assembly Parts\u003c\/h2\u003e\u003cp\u003ePower transfer doesn't stop at the crankshaft. Once your Bully clutch locks up, the kinetic energy must travel seamlessly through the chain, axle, and directly into your wheel hub assembly parts. If your clutch engages too early, the engine lugs, causing a ripple effect of inefficiency that even the best hubs and bearings can't fix. The .085\" black spring delays engagement just enough to keep the engine in its optimal power curve, ensuring that the rotational force delivered to your rear axle is aggressive and sustained.\u003c\/p\u003e\u003ch2\u003eIntegrating with Cycle Parts and Drivetrain Components\u003c\/h2\u003e\u003cp\u003ePrecision tuning requires consistency across all cycle parts and drivetrain elements. The .085\" black spring is manufactured from high-tensile, heat-treated steel to resist thermal fade during extended heat cycles. Unlike cheaper alternatives that lose tension after a few races, the Bully 098-086 maintains its exact spring rate. The black color-coding allows pit crews to quickly identify the spring weight in a multi-spring stack, preventing mismatched tension rates that lead to uneven shoe wear and erratic lock-up.\u003c\/p\u003e\u003ch2\u003eBeyond Standard Wheel Accessories\u003c\/h2\u003e\u003cp\u003eWhile many racers focus purely on tires and wheel accessories to find grip, the real secret to lowering lap times lies in clutch management.
