Product Details

Big End Performance 54030 is a coil-over conversion sleeve kit designed for use in performance and racing suspension applications. These precision-machined sleeves allow racers and builders to convert standard shock absorbers into fully adjustable coil-over setups, enabling fine-tuned ride height and spring preload adjustment.

Key Features:

  • Precision-machined aluminum or steel construction for durability under race conditions
  • Allows ride height adjustment via threaded sleeve design
  • Compatible with a range of popular shock bodies used in circle track and performance applications
  • Improves corner weight tuning and chassis balance
  • Designed for use in dirt track, asphalt, and street performance builds

Big End Performance is a trusted name in circle track and oval racing components. The 54030 sleeve kit is a practical solution for teams looking to upgrade their suspension geometry and adjustability without a full shock replacement.

Great experience! Shipping was fast and the price was amazing. I'd actually wondered if it was too good to be true, but my ramps showed up today (exactly a week from when I placed my order) and they look great.
