So who knows anything about this contraption, price is right, 45 bucks, but does it work.
The High Lifter Spool Locker is an ATV Locker that converts a limited-slip differential to full locked true 4-wheel drive where all four tires deliver full power and unbelievable traction all the time! With a traditional limited-slip differential, frequently only three tires pull.
Installation of the ATV Locker is comparable to the installation of a new clutch pack in the front differential and requires no welding, cutting, or other permanent modification of existing parts on your ATV. The kit includes complete instructions.
Steering in mud or loose dirt is not greatly affected by this product, particularly at speeds over 10 to 15 m.p.h. At extremely low speeds (in low gear, for example), on a full lock turn on concrete or hard surfaces, more effort is required to turn the ATV.
