Good product and price

Cruiser H engine bushes

Great knowledge and communication

Renew timing gears

The gears I purchased were for a chev 6. So I thought that I'd give them a go on my 120 mercruiser and they worked a treat. I bought them for a very good price and received them after a couple of days which I really surprised me. Can't say enough about Precision for there service.

Bolts without nuts

Bolts are good but it would benefit you if you could supply the nuts thanks

Timing Chain

Bought the timing chain set and it was accurate and precisely made. All of the Marks lined up where they needed to be. Very sold timing kit for the Datsun A series engines. Didn’t feel cheap all of the teeth were sharp and everything had weight. Would recommend buying this kit. I would spend the extra to get a nice Japanese OE quality set like this. every part was stamped with Japan so you know where it came from. Great product 👍

Melling m250 cross flow oil pump

Good on price and great delivery service. Online system works well. Pump comes with optional adaptor sleeve for different series blocks- if changing factory fitted sleeve,simply place a tight fitting drill bit inside sleeve and use pliers to twist out and tap optional one in.
