My shop couldn’t find a good 5.4 for my F150 locally. Found Car Part HQ and took a chance. They shipped one out to San Diego and it got here faster than expected. Wrapped nice, zero cracks or rust on the block. My tech said it was actually one of the cleanest pulls he’s seen. It’s been in for 3 months now and still running strong. Definitely not junkyard quality.
transmission was solid. came in 6 days, mechanic had it installed in 1. no complaints here.
I work on cars and needed a decent 4.0L Jeep engine for a customer. These guys shipped it out quick, no sensor damage, good compression. Was a straight swap. Customer was happy, which means I’m happy. Will use again.
I needed a motor for my 2010 tahoe and they sent one to my mechanic in dallas. he said it was clean and installed no problem. runs solid and came with a warranty too.
Bought a transmission for my GMC. Mechanic said it was plug and play. Been driving it 2 weeks, shifts perfect.
good engine fast shipin worked no issues thanks
I’ve bought parts online before and it’s always been a mess. This time it actually went smooth. Ordered a used transmission, showed up clean and wrapped right, went to my guy here in Phoenix. He had it in that same day. Been a month and it shifts great.
Sent the engine straight to my mechanic. He had no complaints and it runs like it should. Delivered in 6 days.
Ordered a 2.4L motor for my wife’s Hyundai. They made it quick and simple. Mechanic said the engine looked newer than expected for a used one. Everything’s working fine and I’d order from them again.
Ordered a 5.7 Hemi motor for my Ram. Shipped to my mechanic in 6 days. He said it was one of the cleaner used engines he’s seen. Running strong so far.
I bought a 4.6L engine for my ’09 Mustang. Ordered over the phone and it got shipped to my shop in Fort Worth in 3 days, no visible damage, and everything matched up during install. Car is back on the road and running strong. I’ve had bad luck with used parts before, but this one feels solid.
Bought a 3.6L V6 for my 2014 Dodge. Ryan made sure it shipped to my mechanic and arrived on time. They got it installed within two days of delivery, and I was back on the road by the end of the week. I’ve had it for three months now—still running like new. The one-year warranty is a nice safety net, but no problems so far.
I installed the transmission myself in my garage. It came in a legit steel cage, which was cool. Took a week to arrive. Bolted right up to my ’06 F150, and it shifted fine on the first test drive. Emailed Ryan with a quick question, and he actually got back same day. The warranty’s nice but hoping I won’t need it.
Ordered a used 5.3 LS motor for my Tahoe. Chris helped me pick the right one and got it shipped o my shop in Colorado. It took six days, which was faster than expected. Mechanic said it was a clean pull and install went smooth. Been driving it two weeks now. Runs strong, no codes.English from USA
I was a little nervous buying an engine online, but Mike walked me through everything. The transmission for my Ram 1500 showed up in good shape, well-packaged. The shop installed it and said all connections lined up perfectly. Been a month, and there's been no slipping, no weird shifts. Solid purchase.
Ryan found me a clean 3.5 V6 for my Honda Pilot. Came wrapped up tight, ports sealed, and no broken plugs. Mechanic said compression looked perfect. I’ve already put 900 miles on it and no lights, no problems. One of the better parts buying experiences I’ve had online.
Got a rear differential for my Ram 2500. Not easy to find used ones in good shape. They had two, had it sent to my local diesel shop. Shop installed it no problem and it’s quiet, no clunking. They even sent the warranty info in the crate. Real deal operation.
