Very very helpful, they are the most nice people an they do what they can if they dont have what you are looking for.

Great place knowledgeable staff friendly expedited service highly recommend to anybody needing anything for their truck

Good people service.

Matched up all parts correctly and they were in stock

I always come here for parts and supplies.

Gary was knowledgeable and very helpful. I got the fittings I needed to get my equipment back on the road.

EXCELLENT CUSTOMER SERVICE TEAM. THEY ALWAYS GO ABOVE AND BEYOND TO FIND YOUR PARTS. ALL YOU NEED IS YOUR FACTORY PART NUMBER AND THEY WILL FIND YOUR PARTS.

Great price! Friendly staff & good selection. It needs a better signage on the street. Thanks

Luke is greatProfessional serviceLarge selection of products in stock

Great place to get parts and supplies for all your Simi Truck needs. If they dont have it they can order it and have it for you the next day. Thats my experience with Principal Truck Supply.

Friendly customer service knowledgeable crew team good prices like this place

Principal part store is a good place for any truck owner to go and pick mid quality part. They have wide section of every thing. I bought my truck shoes from here the service was good and helpful. The only thing I want to mention is about the cashier. She was not in a good mood like the gentleman behind the counter.Any way you could try truck pro on Franklin Rd if you can’t find all the parts here..

Great service, friendly staff, always goes above and beyond.

Principal Truck has a great parts selection with great prices. The parts employees are wonderful also, especially Charlie and Wendy. This place is managed awful, however. It takes forever since every single item has to be checked and counted. Once you get past the parts employees, it is not a good experience. They make you feel like they do not want your business.

DO NOT BUY A BATTERY FROM THEM. They will not let ur exchange your battery even with a warranty.

Great staff and helpful to remedy problem.

Kinda confusing when you first go in but the staff is very friendly and helpful. Pretty much anything you need for the trucking industry.

Good place, good prices, lots on hand and nice people with a lot of product knowledge. but walk in with a return... all Im saying is make sure you really want or need what your buying

A great place to find the hard to find parts for your truck. Great staff and very helpful.

Good prices

Have parts when needed.

Dedicated Principal Truck customer for years. Im not a big spender (maybe $3,000 year) definitely not keeping them in business but will not continue our relationship. I only own two semi trucks but all my parts came from Principal. The parts guys & gal are always busy but very helpful and knowledgable. After your parts are pulled the checkout process is tedious but I dealt with that without incident for years.Today on my very busy Saturday morning I made the 60 minute drive down to principal to get air filters, oil filters, fuel filters, coolant filters, p/s filters, desiccant filters, oil, & additives for my two trucks. All this rang up to $600. I had 3 exhaust parts that I previously purchased (off the regular inventory shelves, nothing special order or etc.) they were the wrong parts, never tried to be installed, in the original boxes & in the same condition they were in when I purchased them. The owner walked over (John I believe) and said sorry I wont take those back. He told me there return policy was 60 days. I explained to the owner that I understood the policy however as he could see these were regular stock items in the condition they were sold to me in & asked him for some leniency due to the fact that I live an hour away and I am a dedicated customer to his store. He looked them up and scanned them into his system sorry those items dont sell well, Im not taking them. This policy is for all customers Then he just walked away and I never saw him again.Presumably his wife, which is always rude and short to others when Ive been in there ( never to me previously) walked over and I said Maam, I have $600 in parts here. I would like the decency to discuss this a bit further, Im a business owner and work hard to satisfy my customers. I believe this is unjust and based on Principal alone cannot accept the answer I was given The lady responded with hes heard enough, his decision is finalUnfortunately they disrespected me as a loyal customer. I have never given them anything less than all my business regarding my trucks. Im a fair and loyal guy, I typically never say boo but Im a principal (pun intended, ironically) man. Once that line is crossed I need to consider the relationship. I was very honest and polite with these folks and even apologized that I would no longer do business with them. I really enjoy having good solid relationships with local businesses. Its getting difficult to keep your money in local shops. This company is playing dangerously, once they forget why they are successful they will sink like a rock. Its there loyal customers who afford them the success theyve found. Anyone can sell wholesale truck parts, finding a good locally owned business with good customer service is a little different.Im giving them two stars for the simple fact that they have a good selection. They didnt sell me bad parts or anything dishonest.

Fast friendly service

Honestly theyre good for selling defective products and not accepting returns. They lost a local owner operator for life. They deserve a no star rating, not to mention they act fairly prejudiced to me.

Great place great people always have parts thats hard to find as well as yard truck parts

Good at making ac lines for truck have large selection of truck parts at reasonable prices

Bring u previous rescipt to match the parts its an ok store . To get u truck done. And cheap.

Parts people are very informative. Prices are abit higher then certain places for items but generally they have alot of parts for most trucks running on road today. Only critique is the road they are based on needs work.

Very knowledgeable. Very helpful. No prices on hardly anything. Would save me a lot of time.

I experienced an awful customer service, and I appreciate the apology of the management.

Great place, im a trucker went in my bicycle from the Pilot truck stop to check it out n see if I can find parts for the KW T700 I drive n the guy was pretty helpful got couple of stuff for an air leak problem, its good to see this kind of places where everything is well organized n cleaned

Knows their parts

Last week treated good helped by staff this week treated extremely bad by apparently the owner who told me and my 3 year old son who loves trucks to leave because he wouldnt make enough money off me to pay the lawsuit if my kid got hurt . LOST A NEW ACCOUNT TODAY. HAVE A NICE DAY !!!

Alot of truck parts and equipment fair prices with a good selection of led lights

Good place to buy Truck parts. Usually have what I need

Great Staff, product selection and prices. The candy store of truck parts and accessories!!

Good place to get hard to find parts

Bought a seat. Once I went to install the seat I found out it was a defective seat that wont lock in position. Came back to principal to fix the problem a day later was told they wont take it back or exchange it for me. Bad business will never shop here again. I suggest you stay away from this as much as you can.

Pathetic.where should we start? how about 8 years ago when I started going to principle truck supply. the very first time I walked in this place I loved it. lots of parts, tools, lights, snow plows, etc. what man would not like principal truck. first impressions can only be made once and luckily the glam or presentation hooked me in the lip. however, I will never forget my first taste of principle trucks customer service. if you want to feel unappreciated, worthless, this is the place for you. anyone who has gone to principle truck knows all to well that you are looked down on, treated like a lesser person, and I have even seen them stereotype individuals. this happened just today when I went in to get parts,. you see, I delt with this for 8 years up until today March 12 2016 .your probuallly wondering why would you keep coming g back for 8 years if you get disrespected?good question. idk. I was tolerant. we all get that way over time but today I drew the last straw of tolerance. here is the real meat to story. my son and I decide to make a 30 minute trip to principle truck today. I tell him, hey son, I need your help choosing new l.e.d. lights for our new truck. I try to make this a big deal for him to pick out lights because he knows it is going on a special truck of mine. kind of a big deal to him, and me, he is only 6 years old. we make it to the store and of course my son is super excited to find new lights for our rig. he does what any kid would do by testing all the lights to see which ones he likes. not a big deal right, Wrong!!! everything is all well until I get a mini lecture from the kind lady who takes your money behind the counter. I am told to keep my child in check because he is testing out lights that are on display for you to look at. Hello, thats what their there for. I forgot to read the keep your kid in check policy when I walked in the door. why is this a big deal? it a big deal for a couple of reasons. here is #1. I ask the guy sitting g behind 5 computer screens for help. he tries to dodge me like you cant see me behind all these screens. I can see you behind their, I just need some help. oh wait, that is principle truck policy to offer terrible service. now Mr 5 computer screen guy is bothered by my persistence with a tricky question. a tricky question which would have saved me $50. so now he is all irritated and finds a way to implement keep your kid in check policy . he cant do this himself though. he has to send nice money collector lady to do the dirty work for him. wth. say it to my face man. what is my kid doing that is wrong, he is turning light switchs on and off. that was the main reason to co.e to the store. I still cant figure what the problem was. here is the other reason why why I am bothered by this situation. I have now read the other reviews for principle truck and another father mentioned he had the same issue at principle truck supply. inocent children being disrespected. that is low. that is so low that i will not be bringin any more business to that store. never ever again. I will also recommended other people to go elsewhere. today was a bad day for principle truck, myself, and my son. today, my son was excited to make an important decision for his father. a small decision was to be made, but an important one for a 6 year old little boy. all he wanted to do was find which lights would be best for dads new truck. however that one simple important decision could not be made because I would not allow my hard earned money to be spent with a company with no respect for children. as we left the store empty handed and drove home, I had to explain an important lesson of appreciation.as a child I remember my love for trucks. I still love trucks to this day. I hope this bad experience with my son does not cause a long term love loss. i hope these bad experiences do not recignate with other families. i hope principle truck can fix their problems, great spirits have always encountered violent opposition from mediocre minds-Albert Einstein
