Product Details

The Whiteline KSB750 Subframe Lock Kit is a motorsport-specific solution designed to eliminate rear subframe movement and optimize rear wheel alignment during high-performance driving. By effectively locking the rear subframe in place, this kit prevents the dynamic alignment changes that occur under hard cornering loads, resulting in more predictable handling and improved track performance.

Key Features:

  • Locks rear subframe to prevent movement under cornering loads
  • Enables more precise rear wheel alignment settings
  • Easy installation and removal between motorsport events
  • Hardware-based solution for maximum rigidity
  • Designed specifically for track and competition use

Important Notes:

  • Motorsport use only - not intended for street driving
  • Increases rear NVH (noise, vibration, harshness) by eliminating subframe bushing compliance
  • Should not be used for extended periods to avoid premature chassis wear
  • Ideal for racers who need consistent alignment and handling characteristics

This kit is perfect for competitive drivers who prioritize maximum performance and alignment stability over ride comfort. The removable design allows you to easily switch between street and track configurations.

Great so far!!!

I ordered on Sat. Dec 29th. With the new year holiday, I expected package to arrive on Wednesday. Was told it would arrive Thursday by the end of the day. I did not receive it until Friday afternoon.. In short, they shouldn't say 2 day delivery, since it took 6 days. I am however very happy with the product I ordered.

was easy to order. I'm very satisfied

Order was received very quickly and as described. Perfect transaction.

Thumbs up!

Lowest price and super fast delivery Autoplicity ROCKS!!

Good

good

Good prices on products. Response by email and phone.

Google searching produced this company as the lowest price on a set of spark plug wires. I like to deal with eBay, but I decided to try it out. Though the shipping was a bit more than Google estimated, it was still the lowest price! The item shipped quickly and was perfect with plenty of communication. Great seller!

Good customer service!!! I ordered a greddy boost controller. Took for ever but they explained why.. And everything is all good!!

ordered a steering box for a dodge truck, beat price i could find no hastle and easy to deal with i call and had a question and recieved an answer while on phone in just minutes.

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.
