Coilovers for (Almost) Everyone￼
If you have a GM muscle car or pickup, chances are good QA1 has a Pro-Coil, MOD Series, or Proma-Star Coilover Conversion Kit for it. The bolt-on kits replace your factory shocks with a ride height-adjustable coilover system to improve handling and ride quality. You can choose single-adjustable (compression) or double-adjustable (compression and rebound) shocks and coil spring ratings to dial-in handling to a T. QA1 even has Mustang II coilover conversions for street rods and kits for Ford Mustangs from 1965 through 2004.
Stronger Axle Shafts Can Handle More Power
When it’s time to replace the axle shafts in your vehicle, take the opportunity to step up a couple notches and get quality shafts like those from Yukon Gear and Axle. They make direct-fit one-piece axles in 1541H alloy steel (25% stronger than stock axles) and 4340 chromoly (50% stronger than stock axles) that can handle more power and bigger tires without a whimper. If you need cut-to-fit shafts for a custom axle setup, Yukon Gear makes those for many popular axle types.
