Updated Spline Lock: More Spline, better lock, now available with no-slip guarantee!

[BlownOne]

This is what EaS recommended and what I used as a preventative measure in my build!

[QUOTE=Chris@VargasTurboTech;24867151]We at VTT are very excited to release our updated Spline Lock. Let's get right into all the details:

Basics: Why a spline vs. a key or pin?
While there are many ways to solve crank hub slip issues, of the three major methods (spline, key, pin) the spline is the only one primarily designed to transmit torque. Splines are considered to be "torque dense", meaning extremely efficient at transmitting torque, and do not suffer from balance issues as can be had with some key/pinned setups. Typically many splines are used, which means a more uniform transfer of torque and a lower loading on a given part of the shaft/hub interface. Don't take our word for it though, just look at your own car; transmission input shafts, axles, clutch disks and more all use splines as the chosen torque transmission method. As we see it, the only disadvantage of using a spline over a key or pin is in the manufacturing cost. Don't trust us though, do a little google searching and you'll find this to be repeated many times, a couple quick examples in no particular order (if you want some light spline related reading for the evening):



So you’re saying I shouldn’t trust you is what I took away from the first paragraph

Simple. If installed by our shop (VHP in Hayward CA) or one of our approved shops (right now that list includes EAS, and in PR Bimmer Solutions) we guarantee the hub won't slip. The no slip guarantee says the spline lock will not slip for the life of your engine (original owner only). If any issues arise (they won't), diagnosis and/or repair must be performed by VHP or approved installation shop, which is just another way to saying we want people who know what they're doing installing it, and if anything comes up, we want those same qualified people repairing it. If found to have slipped, we will replace the hub, and labor at no cost. This does not cover any possible engine damage.

Does your no slip guarantee cover the cost to re-time the engine if the hub still slips? (assuming no other engine damage besides the SCH)

You have to retime the engine when replacing the hub, so yes.
