Wilwood 140-12101-R is a D154 rear caliper kit with 120-11874-RD two-piston floating calipers in red powder coat. It is a direct bolt-on replacement for the factory single piston "Metric" calipers used on many custom rear axles, and it gives a matching rear option for Wilwood D154 front calipers. The calipers have forged billet aluminum bodies, stainless steel pistons and high-temperature seals, mount in the stock location over stock rotors, use OE style D154 brake pads and take an OE M10-1.5 banjo bolt brake line. The kit includes hardened slide pins and BP-10 pads.
Notes:
- Rotors are not included; the calipers fit over the stock rotors.
- The calipers can be used with most wheels that clear the OE calipers.
- Piston area differs on the product page: the description gives 1.96 sq-inches, while the caliper specification lists 1.98 in².
- Brake lines are needed. The calipers use an OE M10-1.5 banjo bolt line mounting.
- Other finishes: 140-12101-BK (black calipers).
