188mm (Standard) BMW Differential 45/45 Standard Pressure Ramps
When limited slip units are not serviced before end of life of the clutches, damage can occur to pressure surfaces (ramps) touching the clutches. Great news is that we offer a service to exchange for good condition ones! This set is factory 45/45 ramps found in most BMW 188mm LSD units.
While returning a core set of ramps is no longer not necessary, if you send us a refurbishable set of ramps, we will issue a $175 refund.
To return a set of ramps for a refund, follow these instructions:
- Ramp set must be suitable for recycling into this program.
- Securely package the ramps along with a copy of the original order invoice and ship via USPS small flat-rate box to: Thayer Motorsports, PO Box 1453, Ashland, VA 23005.
- USPS is the only acceptable shipping vendor for core returns. The required USPS small flat-rate box is very cost effective. Confirm your shipment is appropriately insured and tracked before sending - we are not responsible for lost or damaged packages.
- Once inspected by a member of our staff, a refund will be generated to the original method of payment.
