#6978 - SPUR GEAR 78 TOOTH (48 PITCH)
Discontinued, replacement part: #6975
Tune your car or truck for maximum top speed or faster acceleration with a new spur gear. A smaller spur gear gives you more top speed but slower acceleration and less runtime. You'll see faster acceleration and longer run time, but less top speed, with a larger spur gear.
Will NOT work with 64DP pinion gears, must be used with 48DP pinions.
