Brake Booster For Jeep Wrangler YJ 1987-1990 2.5L & 4.2L (Replaces 54-74004, 5252628)

About This Product

Got a classic Jeep Wrangler YJ (1987, 1988, 1989, or 1990) with a 2.5L or 4.2L engine? If your brake pedal is getting really hard to push and you feel like you need to stand on it to stop, your vacuum brake booster is probably failing. This is a direct replacement part that matches OEM numbers 54-74004, 5252628, and 83502846. It's a single diaphragm style, made from steel, and has a 3/8x16 thread size for the master cylinder studs. Installing a new booster restores that power-assisted braking feel, making driving safer and easier. Before you order, please double-check: 1) Your Jeep's exact year and engine, and 2) that your old booster looks like the one in the pictures. This is a critical safety component, so getting the right fit is key. The part comes with a 12-month warranty for peace of mind. Get your braking power back!
