Product Details

The QA1 MG401-10550C is a Pro-Coil Aluminum MOD Series coilover shock kit engineered for serious performance applications. Featuring double-adjustable damping with a low-speed bleed circuit, this kit gives drivers precise control over compression and rebound tuning to dial in handling for road racing, autocross, or high-performance street use.

This kit is built around a remote canister design that separates the oil and gas charge from the main shock body, reducing heat buildup and improving fade resistance during extended use. The aluminum construction keeps weight to a minimum without sacrificing durability.

Key Features:

  • Double adjustable damping with low-speed bleed for fine-tuned compression and rebound control
  • Remote canister design for improved heat dissipation and consistent damping performance
  • Stock mount configuration for straightforward fitment
  • Compressed height of 8.63", extended height of 12.63"
  • Includes 10" large tapered flat spring rated at 550 lb/in
  • Lightweight aluminum body construction
  • Part of QA1's modular MOD Series platform for easy component swapping and upgrades

The included 550 lb/in large tapered flat spring pairs with the shock's valving to deliver a balanced, performance-oriented ride. The MOD Series platform is designed for versatility, allowing racers and enthusiasts to swap springs, mounts, and other components as build requirements evolve. QA1's Pro-Coil kits are manufactured in the USA to exacting tolerances for consistent, race-proven performance.

Nice

Happy with results.

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.

good price, fast shipping, no issues to think of. Thanks

Easy ordering!

Great experience. Easy, quick, great price
