Featuring a CNC-machined billet 6061-T6 aluminum housing and a precision-machined centerless ground shaft with a 4-micron finish, the distributors ride on permanently oiled bronze bushings for high-speed durability and endurance. They're equipped with a self-contained electronic control module, a machined reluctor, and a magnetic pickup for dependability. An adjustable mechanical advance system allows you to easily tailor an ignition curve to match your engine's needs, while the additional vacuum advance can be tailored for optimal fuel economy. The adjustable vacuum advance is factory dialed-in for 10 degrees of advance at 10 in. of vacuum, with a lockout replacement insert for mechanical advance only. The easy-to-adjust mechanical advance has a range of 0-28 degrees in 1 degree increments, and a factory dialed-in high-performance ignition curve starting at 1,200 rpm, with 24 degrees of advance at 3,000 rpm. Lastly, each distributor is topped off with Accel's legendary 60 kV tan alkyd cap and balanced rotor with brass inserts, for long-lasting performance. They're compatible with most aftermarket capacitive discharge ignition systems.
