Ottimo upgrade

thank for good roduct and fast delivery...item nice and received in good condition..

Looks to be a great upgrade!!! Will update the review when I actually install these. The original diffs seem to be pretty tough, but going to metal is always nice for longevity & weight. Really makes a car feel Hobby grade, so super excited to swap these in soon! Banggood always does a great job shipping it out fast & safely!! Take a lil while to get here to US, but no worries nor hurries!!

Great metal option for diffs!!! Original diffs haven’t blown yet, but once they do I’ll instal these cool metal gears!!!
