DBK6272A-40 - 1962-1972 Mopar A Body Small Bolt Pattern Standard Disc Brake Conversion Kit

Mopar A-Body Disc Brake Conversion Kit, Small Bolt Pattern (5 x 4")

Bolt-on drum-to-disc conversion. No new control arms needed.

Our redesigned Mopar A-body disc brake kit takes the hassle and much of the cost out of a front disc conversion. It's built from all-new parts and bolts onto your existing control arms, which can save you 25% or more compared to conversions that make you replace them. You get stronger, more consistent stopping without rebuilding your front end.

⚠️ Before you order: confirm two things

1. Your bolt pattern is 5 x 4" (small bolt pattern)
This kit is for the 5 x 4" small bolt pattern found on many early-'60s A-bodies. We also offer a 5 x 4.5" version, so make sure you order the one that matches your car.

How to check: on a 5-lug hub, measure from the center of one stud to the outside edge of the stud across from it (skip the one next to it). About 4" means you need this kit. About 4-1/2" means you need the 5 x 4.5" kit.

2. Your wheels will clear the calipers
This kit fits most 14" wheels, but not the very narrowest 14" wheels Mopar ever made. Your wheels must have:

• At least 13.25" inside diameter, measured across the inside of the barrel
• At least 4" backspacing

How to check backspacing: lay the wheel face down, set a straightedge across the back rim lip, and measure straight down to the mounting pad where the wheel touches the hub. A wheel that falls short on either measurement won't clear the calipers.

What's in the kit

• 11" standard rotors, 5 x 4" bolt pattern
• Loaded large calipers
• Lower ball joints
• Spindle sleeve adapters
• Stock-height spindles
• Backing plates
• Rubber brake hoses
• Bearings, seals and dust caps
• All mounting hardware

Why choose this kit

• Bolt-on conversion: keeps your original control arms.
• Saves you money: 25% or more compared to kits that need new control arms.
• All-new parts: a redesigned kit, not reused or rebuilt parts.
• Complete package: everything you need for the front end in one box.

Please measure before you buy. Checking your bolt pattern and wheels is the buyer's responsibility. Returns are accepted, but the buyer pays return shipping plus a 15% restocking fee on any returned kit.

Changes I made:

• Warnings moved up: the bolt pattern and wheel checks now sit near the top, so buyers see them before they order rather than after.
• How-to-measure tips added: these should cut down on wrong orders and returns.
• Spindles and backing plates split: your list had "Backing Plates Stock Height Spindles" on one line, so I made them two items. Fix that if it's actually one part.
