Their parts are cheap junk. Review of DNJ valve lifters - I bought 16 DNJ valve lifters from RockAuto in November 2014. 5 of 16 lifters were defective - they never worked - they had 6 to 10 thousands inch clearance even after driving the car and after following the valve lifter filling instructions. The clearance should be 0. These are cheap chinese made parts. Since I didn't finish putting in the lifters until Feb 2015 Rockauto refused to refund my money and refused to accept back the parts. They said there was only a 30 day money back guarantee. Instead they offered to replace the defective lifters. Of course with a 31% defect rate I would have to disassemble the engine a third time to replace the defective replacement parts. It takes over 10 hours of labor to replace the valve lifters. I also bought a water pump from Rockauto (Gates - made in China). It lasted 18 months before failing and I only drove the car 4,000 miles. Stay away from this company at all costs! Pay more for real parts - rockauto does not save you any money!
