Sweeting Performance Engineering Marketing & Design

Sweeting has had my money ($2000) for 5 months...they were supposed to have completed in 90 days. They do not respond to emails or voicemails. DO NOT send them any money. They are a 3rd Generation company, clearly the 3rd generation is not on point or care about their customers. STILL WAITING

Poor service...read all reviews before you make any purchase from this company

My experience has been frustrating. First of May my mechanic sent $2000.00 to Sweeting...that is 150 days ago, the terms say 90 business to complete. It has been 110 days...my frustration is after multiple emails and voicemails not a response from Sweeting Performance...only read terms and conditions which state 90 business days and they have exceeded that. Buyer beware... they have my 2k and they are not responding.
DO NOT SEND THEM ANY MONEY

I HAVE A LAND ROVER DEFENDER AND THE SWEETING POWER BOOST WAS JUST THE RIGHT UPGRADE I NEEDED AFTER THE LS SWAP

Pro tip for anyone hunting parts: finally found a supplier stacked with 24v brake booster backup motors (impossible to find when you need 'em, unlike the 12v ones). They even had a few different 12v variations in stock, which is a massive bonus for the rest of my trucks.

After making the mistake of buying a booster from a different seller, I realized I’d just been sent a cheap, flakey Cardone rebuild covered in rust—and for the exact same price as a brand-new unit from Sweeting! Needless to say, the other company was completely useless when I reached out with a technical question.

I went looking around and called Sweeting directly. Not only did he clear up my technical hurdles within a few minutes, but he also got me pointed completely down the right path. Phenomenal customer service and an absolute lifesaver of a resource!

Best money I ever spent on my Camaro was buying my hydro boost from them roughly 9 years ago. I actually spotted them cited as the expert source in a MotorTrend article online recently. That completely mirrors my own experience—they're truly the only ones who really know what they're doing

Finding brake parts for an older Chevy C70 is becoming nearly impossible, so I was relieved to find Sweeting Performance. I needed a replacement for the Hydro-Vac system on my farm truck, and instead of spending countless hours hunting for obsolete parts, I was able to install their conversion. It wasn't inexpensive, but considering what a new truck costs today, it was a very worthwhile investment.

The kit is well thought out, the components are high quality, and it solved a problem that many owners of older medium-duty trucks face. Companies willing to engineer solutions for vehicles that manufacturers stopped supporting decades ago are providing a valuable service.

My experience with Sweeting Performance has been positive from start to finish. The product worked as advertised, my truck is back on the road, and I have confidence in the braking system again. If you own an older Chevy C70 or another classic medium-duty truck and are struggling to find brake components, Sweeting Performance is the way to go. They're helping keep these old workhorses operating instead of sending them to the scrapyard.

I’m glad I reached out to Sweeting Performance. I originally bought a hydro-boost system from another vendor and ran into problems that they couldn’t diagnose or help me solve. Even though I wasn’t their customer for that part, the team at Sweeting Performance immediately knew what the issue was and walked me through the fix. Their knowledge and willingness to help got everything working perfectly on my '60s big-block Chevy.
Looking back, I wish I had called Sweeting Performance first. They were friendly, patient, and clearly know these brake systems inside and out. It's rare to find a company that takes the time to help someone, even when the product wasn't purchased from them. Based on my experience, I wouldn't hesitate to recommend them to anyone looking for quality brake components or expert technical support. Great people, excellent customer service, and truly knowledgeable.

I have a '60s Mopar, and finding brake components that actually fit the application and perform the way they're supposed to isn't always straightforward. Sweeting Performance took the time to answer my questions, explain the options, and recommend the right hydro-boost setup for my car instead of just trying to make a sale.

The installation went smoothly, the parts were well made, and the difference in braking performance is outstanding. The pedal feel is excellent, stopping power is dramatically improved, and the system has worked flawlessly since installation. It's one of the best upgrades I've made to the car.

Based on my experience, they're knowledgeable, helpful, and clearly know these older Mopar brake systems inside and out. Custom and specialty parts aren't the same as ordering something off a warehouse shelf, so I think it's worth having realistic expectations and communicating with the company if you have questions.

I'd buy from Sweeting Performance again without hesitation and would recommend them to anyone looking for a quality brake upgrade for a classic Mopar.

I ordered a hydrobooster from Sweeting 9 months later nothing... I'm filing a complaint here:

Maybe this will light a fire under their tails...

I ordered a hydroboost kit in February of 2025, it has been 15 months. All I got was the hose kit, still waiting on the hydroboost and wilwood master cylinder. Once in a while I get a reply to my emails saying I will be notified when the parts ship. I am pretty sure I got scammed

THE HYDROBOOST KNOCKED MY SOCKS OFF, BEST UPGRADE THAT I MADE ON MY RIG

Everything in my kit was OE quality or better. Superb.

night and day difference after swapping vacuum brakes to a sweeting hydroboost. best upgrade for the money.

Exactly what I needed after my brake upgrade. Works perfectly.

It took a day to connect, but they solved in minutes what others couldn’t in weeks.

I order and paid for a brake booster on 10/27/22. As of 12/13/23 I've yet to receive it. I have several email promising a tracking number and ship date. Plenty of excuses as to why the delay. Buy at your own risk.

Ordered a hydro boost got my Jeep on March1st 2023. After about two weeks I emailed them to inquire about a possible shipping date. I was told ten weeks. That date came and went so I contacted them again. This time I was told 5 more weeks. That date came and went. Emailed them again told them to either ship the booster or cancel the order and refund my money. This time I got no response. Tried to call, couldn’t leave a voicemail. It’s now September 29th and still no response. I have now filled a complaint with the BBB, and will be posting unsatisfactory reviews wherever I can. Hate to say it but so far Sweeting looks like a thief that stole my $826.00.

Placed order October 30 2022 with website saying 30-60 day leadtime. I figured with holidays it might take a little longer. So on February 1 2023 I email asking what is going on. I was told there was a delay with hydro-boost it will be 7 more weeks. So on April 20 2023 I contact again saying 7 weeks have come and gone whats the deal and said if it not shipped by April 28 I would like a refund. I was told order was complete will see email with tracking shortly. So on April 28 I get an email with tracking today is May 2 2023 and its still not shipped. I have contacted my credit card company today to file for a charge back since my item is not shipped . He has very poor business with telling the truth and if you are that busy maybe you need hire someone instead of lieing to people.
