Customer Reviews
Overall rating: 4.8 / 5 from 675 reviews.
Everything was there. Great quality and came on time. Also got a great deal on items, lower than anywhere else.
La livraison se fait en un temps record, malheureusement il y a eu un erreur de pièce, par contre un service très professionnel, facile d'accès et dans ma langue natale..... Le retour est accepté sans frais. Tout les professionnels dans le domaines de la mécanique savent que des erreurs survient aléatoirement au niveaux pièces un jour ou l'autre, pas très agréable mais la ou ce joue la qualité du service est le service après vente et je peux confirmé la compétence de l'équipe Parts Pionner... Merci à l'équipe
Toujours en attente du ticket de retour mais j'ai confiance dans leurs bref délais...
LB Mécanique générale vous remercie et aux plaisirs de refaire affaire ensemble....!
This was my first dealing here. Easy to browse the site,the ordering process was quick and straightforward and shipping was fast and flawless. 10 out of 10.
Parts were well packaged, came with all hardware needed for clips, anti rattle clips, as well as mounting hardware. I drove the car to have the car relearn piston positioning, and these are much more grippy than factory honda/acura pads and rotors, so I am really happy with them. I am surprised it only took 3 days for them to arrive after ordering them from Calgary to sw ontario. I have already recommended part pioneer and this brand of pads and rotors to my friends.
Parts came really fast and of good quality as I’ve been a licensed mechanic for over 25 years departure just as good or better than buying in your local parts stores
