Roll Centre AdjustersHardrace Roll Center Adjusters are special CNC machined spacers to correct the roll centre on lowered cars. This relieves some of the angle on the driveshaft CV joints and will prolong CV joint life this is why we call it the Driveshaft Saver. Driveshafts are a common fault with P1 chassis cars and it is easy to see why there are tons of lowered cars! Even a drop of 50mm can wear driveshafts quickly and they are not cheap to replace.

Hardrace Roll-Center Adjusters are special CNC machined spacers to correct the roll centre on lowered cars.  This relieves some of the angle on the driveshaft CV joints and will prolong CV joint life - this is why we call it the Driveshaft Saver. Driveshafts are a common fault with P1 chassis cars and it is easy to see why - there are tons of lowered cars! Even a drop of 50mm can wear driveshafts quickly and they are not cheap to replace.

By installing the Hardrace Roll-Center Adjusters, it will correct the suspension geometry of a lowered car, putting the control arms back closer to its original position, resulting in increased steering response and stability while eliminating bump steer. 

  • Decrease roll
  • Improves tire contact patch with the road
  • Increases steering wheel responsiveness
  • Enables increased cornering force
  • Prolong driveshaft life
The Roll-Centre Adjusters are also bundled with uprated Hardrace ball joints. You should replace the ball joint as they can be easily damaged during removal and are not designed to be fitted with RCA Plates.
Optional Upgrade Extended Tie Rods:
The OEM Tie Rod Ends will have to be adjusted to compensate your steering angle for the new ball joints. They will toe in without adjustment. Adjusting the OEM Tie Rod ends may result in the Tie Rod End only being attached by a few threads. 
The Hardrace Extended Tie Rod Ends have a deeper socket and will have sufficient thread to allow for full adjustment.


Fitment Notes: Hardened Rubber. Tie Rod Ends not included. Ball Joint size depends on chassis number. Check the last 6 digits on your VIN code, that will be the chassis number.

Avoid this product on Amazon
Flavor Name: Chicken & Sweet Potato, Size: 10.5 Ounce (Pack of 1)
I will never buy this product off Amazon again. My dog who recently passed got sick on this product when I bought it from Amazon, I thought I'd try it with a different dog, same awful results and I'm just out money. If your dog likes these I recommend Chewy. And Amazon doesn't refund food 😡 maybe they are waiting for someone to sue them or die before they change that policy!!

Way too expensive here
Pattern Name: Mega Roll Natural
The Frankly collagen chew is fine, per our Lab. We ordered this because it is out of stock at our normal store. The chew is 5 stars, but the price is 1 star. We were ripped off!!
