Introducing the Sonnax Tool Shop

Through customer calls, emails, surveys, and conversations at industry events, we heard you loud and clear: some Sonnax tools have been hard to get, and the prices were too high. We brought your concerns to our distributor partners, and worked together to build the Sonnax Tool Shop.

The goal of this program is simple: help you get the tools you want, when you want them, at a fair price. The Sonnax Tool Shop includes 70+ popular F-tool  and vacuum testing products with new, lower MSRPs and greater distribution at local branches and regional distribution centers.

“At the Sonnax Tool Shop, the price you see is the price you pay,” says Mark Kaplan, Sonnax Vice President of Sales. “We’re grateful for the support of our network of distributors in offering MSRP-or-better prices and 1-2 day delivery on this selection of tools to all customers in the U.S. and Canada.”  

A key benefit for rebuilders: If a Tool Shop part or kit isn’t readily available from your regular local branch, you can call other Sonnax distributors without worrying that you’ll have to pay more.

Introducing the Sonnax Zip Valve™

Need or prefer a drop-in repair for common shift problems? 

Introducing Zip Valve™ products – a new brand covering the hundreds of drop-in valves and Zip Kits rebuilders have trusted for years to overcome chronic transmission problems. These easy-to-install components deliver quality and performance that can’t be beat thanks to upgraded Sonnax design features, improved materials and precision manufacturing. 

More than 350 different products covering 200-plus transmissions are available, and it’s easy to identify these parts anywhere on the Sonnax website by the new, drop-in “ZIP” logo that accompanies each one. Just like you can narrow down search results by unit or part type, choosing to display only Zip Valves is now another option for quickly finding just the right repair. 

“At Sonnax, we strive to have the best selection of highest-quality solutions available for our customers.” says Sonnax President Steve Boyer. “When you’ve got a build on your bench, it’s our job to provide you with a wide range of options you can trust.”
