We now offer Isotropic Superfinishing on all our Speedtek Products.
(This process will increase the time from when we could dispatch the kit, please email us if you have any questions)
Superfinishing is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone to grind the gears and other parts ; this layer is usually about 1 μm in magnitude. Superfinishing, unlike polishing which produces a mirror finish, creates a cross-hatch pattern on the workpiece.
Advantages of superfinishing include: increasing part life, decreasing wear, closer tolerances, higher load bearing surfaces, better sealing capabilities, and elimination of a break in period.
Our solid 6-month unconditional warranty program for all our manufactured gearsets, you can be confident that your investment is well-protected.
Our extended warranty program is available, for more information : Extended Warranty Program now Available with our Performance Transmiss – Speedtek Auto Racing
