Just got this repair kit for my pre-2012 Polaris PB4-60 booster pump. The description was accurate about compatibility, which saved me from ordering the wrong version - major plus!

Installation was straightforward, though wrestling with Polaris pump parts is never truly 'easy'. The included O-rings slid into place nicely and my pump stopped leaking immediately. Been running smooth for 2 weeks now.

However, I noticed the shaft seal feels slightly less durable than OEM parts. Not a dealbreaker for the price, but I'll keep an eye on longevity. Also wish it came with a tiny tube of lubricant - had to use my own pool grease.

Biggest win? Saved me $300+ compared to buying a whole new pump assembly. For occasional maintenance, this budget-friendly kit gets the job done if you're handy with tools.
