High Strength Collar Gear - 6spd M66 Version

Sorry we're sold out again.  If you would like to see another group buy for this product please send me an email.

At typically over $1000 per replacement including labor, and some reportedly needing more than one before they've hit 100k miles, this expensive problem has finally been dealt with. Install this collar gear as a preventative measure and let your drive train worries slip away.

I can not guarantee fitment on a worn transmission output gear or angle gear input gear so don't wait till it fails!  However, one of the prototypes was recently installed on a car with a failed OEM collar and he had this to say...

• "...it feels stronger & heavier, tighter fit, correct Volvo gaskets - I'm happy to support this new collar..."  See the reviews here.

Ryan's personal log:  70,000+ miles from June 2013-2019.  Likely over 3 million combined miles with the over 200 units sold.
