Return details & how to start

Request return authorization (RMA) within 30 days of delivery for eligible items. Keep items unused and uninstalled, with original packaging and accessories. Electronics, liquids, special orders and other categories are excluded.

Email sales@frsport.com with RETURN and your order number in the subject to request an RMA. Please wait for return authorization before sending your item back.

Wrong part/size or change of mind: a 20% return processing fee applies, plus applicable shipping costs.

Original shipping is non-refundable. For orders shipped free, the actual outbound shipping cost is deducted from the refund. Return shipping is prepaid by the customer.

After payment capture, cancellations and refunds generally incur a 5% processing fee, except for our error, confirmed defects or confirmed carrier loss. The 5% and 20% fees do not stack; only the greater applicable fee applies. Store credit waives the 5% fee, but applicable return fees remain.

Missing, incorrect or transit-damaged items: report within 3 business days of receipt with photos of the product and packaging.

For defective items, contact us for help with the manufacturer's warranty process. The manufacturer decides the claim.

Manley pistons are machined of high strength 2618 material. Each design is lightweight yet robust enough to deliver long service life. Offset wrist pin design is utilized for quiet start-ups. Perfect ring groove to skirt squareness is achieved through our unique "one fixturing" manufacturing method that assures maximum horsepower. All pistons come with moly coated skirts. Round wire locks, premium chrome moly wrist pins, and premium steel top ring sets from Total Seal are included with every kit at no additional charge. 9310 alloy upgraded wrist pins are available. Recommended clearance: .003" for mildly boosted and .0035" for highly boosted measured .850" (79/83mm Strokes) and 1.100" (75mm Stroke) from the bottom of the oil ring groove.
