Why Buy the PROFORM HEI?

We purchased and evaluated a selection of low-cost Chinese and Australian distributors to find the answers...

PROFORM's HEI distributors are different overall: the other products evaluated are characterized by crudely manufactured individual components with machining marks, evidence of rough manufacturing processes, inferior high-temperature lubricity, and uncontrolled metallurgy (uncontrolled hardness and inferior metal specifications).

First-rate design and material specifications, plus rigorous manufacturing controls, explain why PROFORM was awarded the OEM contract to supply the factory HEI distributor that is sold separately and used on numerous crate engines.

Each PROFORM distributor is functionally tested individually on a $75,000 custom-designed testing machine. We don't ask our customers to test them for the first time!

The PROFORM HEI features a uniformly hardened, polished shaft to maximize strength and reliability.Lower cost competitive units were found to have inconsistent hardness from unit to unit, and even throughout a given shaft -- resulting in deformation and unnecessary, premature component wear.

PROFORM's HEI distributors feature a hardened gear which has a final, highly controlled cut for precision and endurance.

PROFORM HEI's feature brass bushings with a self-lubricating feature for greater longevity. Lower cost competitive units are made of sub-standard material prone to wear out quickly.

The PROFORM HEI features a cap and coil made in the U.S.A. The shaft and gears are manufactured in ISO 9000 certified manufacturing plants.

PROFORM HEI's feature hardened weights for maximum durability and minimized wear. Low cost competitive units use ordinary metals that have not been heat treated -- resulting in burrs and other irregularity which will cause variations when matching the cam.

The PROFORM HEI is superior in appearance to lower cost competitive units, and it is packaged in full-color boxes loaded with helpful, self-selling features and benefits.

PROFORM HEI distributors are offered at a competitive, more affordable WD price, keeping you competitive when selling one of the hottest HEI distributors with the most genuine product value. As noted above, PROFORM's distributor doesn't cut corners -- PROFORM means performance.

Don't be fooled -- lots of little things add up...and make a genuine difference in performance, reliability, and durability!
