Wilwood D52 twin-piston caliper kits are two-piston calipers that replace the factory calipers and use stock rotors. It has stainless steel pistons and high-temperature seals, while its body is composed of forged billet aluminum. Designed for street and track use, these performance caliper kits are low-maintenance, light, and dependable. Its innovative design overcomes the problems of rust, bore pitting, and seal failures that affect other OEM calipers. The front and rear pads and sliding bolts are included in these enhanced red powder-coated D52 caliper kits. Meanwhile, the D154 Rear Caliper Kit from Wilwood is a straightforward bolt-on 2-piston alternative for the factory original single piston "Metric" calipers seen on many aftermarket application rears. With the added benefit of reduced rear piston dimensions (1.96 sq-inches of area), which isn't generally found in OEM calipers, this caliper kit provides proper front and rear bias. The forged aluminum bodies, stainless steel pistons, and competitive type high-temperature seals eliminate rust, bore pitting, and seal failures. For the street and track, D154 calipers offer low-maintenance performance, significant weight reduction, and high-temperature dependability. The D52 calipers use the original model D154 brake pads and an OE M10-1.5 banjo bolt brake line installation.
The D52 caliper is a simple two-piston upgrade for many 1968-96 GM automobiles and trucks. Using forged billet aluminum bodies, stainless steel pistons, and competition-type high-temperature seals eliminates rust, bore pitting, and seal failures in OE calipers. D52 calipers are perfect for both the street and the track. 1978 saw the introduction of Wilwood's D154 Front Caliper Kit, a direct bolt-on 2-piston replacement for the OE cast iron "Metric" calipers seen on many mid-size GM cars and compact trucks. GM utilized this caliper until 2002. Rust, bore pitting, and seal failures are eliminated using forged aluminum bodies and stainless steel pistons. D154 calipers are low-maintenance, light, and reliable. D154 calipers use OE D154 brake pads and M10mm x 1.5 banjo bolts to mount brake lines. Most wheels can use D154 calipers.
