Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’

General brand comparisons with Moog and Mevotech

“I don’t really shop brand names but look for quality amongst certain brands cause every brand name will have their flaws aka stay away from Detroit Axle 🙅🏾‍♂️ TRQ is way better.”➕

Confusion over specifications and comparisons

Concerns about reliability of various aftermarket brands

“I heard some bad stories about their ball joints.”➕

Discussion on the impact of road salt on coil springs

“it's mind blowing how much damage using salt for de-icing does to a vehicle.”➕

“To be fair, the Escort was known for failing rear springs.”➕

Challenges with electrical installation

“It was more than I was comfortable with and it’s a commercial building so I wanted it up to code.”➕

“The electrical has to be the easiest part.”➕

Advice on managing coil whine

“My advice, in all honesty, is to put up with it for a bit.”➕
