Special Order / Custom Made NST Pulleys Custom Water Pump Pulley -

This page is for customers looking for pulleys that we do not mass produce and list on other pages of our site. ​ NST has the ability and expertise to offer special order items for tuners who require pulleys specifically machined to their unique needs. 

Special orders requiring custom machining MUST BE discussed with AND approved by NST, via email, before payment is made. Special order items can require up to 60 days, this process can not be expedited and is as a direct result of market conditions, current demand, and current support from the community.  

Promo/Discount Codes can not be applied to special order items. 
​Special order items can not be cancelled after payment is processed and machining has started. 

Each kit is CNC machined from 6061-T6 aircraft quality aluminum (or stainless steel) and is tested for tight machining and balance tolerances. Every NST pulley is anodized for exceptional durability and is available in a choice of colors.
