Prevent Premature Cylinder Bore Wear

OE plastic accumulators are prone to breaking and have poor sealing qualities, and metal rings currently offered with aftermarket accumulators also have issues with sealing. Sonnax accumulator piston kits feature a stronger piston made from anodized billet aluminum and a dual seal design. The piston's PTFEs seals prevent piston-to-bore contact and the D-rings vastly improve sealing compared to aftermarket steel rings. Sonnax also offers aluminum accumulator covers. Machined from billet aluminum, these covers provide a strong yet lightweight alternative to OE accumulator covers.
