This is a great tool fits like a charm and for the value for money great deal. It help ease the removal and held while torquing down 250 ft lbs.

The locking tool/socket are surprisingly well made. Very stout, great finish, very precise. (No burs or defects on the socket or holding feet.) Honestly I think the socket alone is worth more than the price of the whole kit. I'll be looking out for other products from this company based on what I see with this locking tool kit.

Used this to lock my flexplate so I could get the harmonic balancer bolt off. Performed as advertised.

I am restoring an old 1600 VW Engine and unfortunately the flywheel takes a 36MM socket. As such, to remove or reinstall the flywheel during restoration I needed this 36MM set. It’s not so easy to find a 36MM socket and this set is great. It is super well made, heavy, strong, and the flywheel kit is also a big plus for me. The set is for a Duramax engine so my use case is quite different, but this works perfectly for my needs. Very happy with this set’s quality, build, and price. Definitely a recommend.
