Wilwood's D154-DS forged billet caliper is a direct bolt-on, lightweight, high-strength, extreme duty alternative to the OE cast iron calipers that were used on a wide range of factory disc brake equipped mid-size GM cars and small trucks beginning in 1978. Use of this caliper can still be found on some GM models as late as the year 2002. D154-DS calipers incorporate an exclusive dust wiper seal that further protects the piston bore from dust and corrosion, allowing the caliper to be used in locales that mandate a method of environmental sealing. The wide spread and affordable availability of D154-DS calipers and brake pad compounds also made it a popular choice in a number of restricted class competition categories and drum to disc conversions on all types of hot rods and street machines.
