Prothane 74.5-80 MG MGB Front Crossmember Mounts - Red - 26-49021

The Prothane Front Crossmember Mount Kit (part #26-49021) is a direct-replacement front cross member bushing set engineered specifically for U.S.-model MG MGB roadsters produced from mid-1974.5 through 1980. If your classic British sports car is suffering from the vague, wandering front-end feel that comes with decades-old rubber crossmember mounts, these polyurethane bushings from Prothane are the straightforward fix — available in eye-catching red to complement any engine bay build.

Key Features & Benefits

• Polyurethane construction for greater durability: Prothane's polyurethane material is designed to outlast the original rubber mounts, resisting compression set, oil, and the weathering that degrades factory bushings over decades of use on a vintage MGB.
• Improved comfort and front-end response: According to Prothane, their parts provide greater durability and comfort compared to the originals — meaning you get a more consistent, predictable feel from the front crossmember without sacrificing ride quality.
• Available in red or black: The 26-49021 kit is offered in both red and black colorways, letting you coordinate with other Prothane bushings throughout your suspension build.
• Lifetime warranty: Prothane backs this kit with a lifetime warranty, a strong indicator of confidence in the product's longevity.
• Made in USA: Prothane manufactures their polyurethane components in the United States.
• Direct-fit kit design: The kit is purpose-built for U.S.-specification MGB models, so there's no guesswork about whether the pieces will work with your crossmember mounting points.
• Drop-in upgrade for restoration or performance builds: Whether you're restoring an MGB to road-worthy condition or building a weekend driver, replacing collapsed or cracked factory crossmember mounts is a foundational suspension refresh that makes every other handling improvement more effective.

Fitment

This kit is designed for U.S.-specification MG MGB models. Confirmed fitment based on available sourced data:

• 1975–1980 MG MGB — MK IV
• 1975–1976 MG MGB — V-8

The product name references mid-1974.5 (74½) through 1980 as the application window per Prothane's own listing, which aligns with the late-1974 U.S. model year changeover. If your MGB predates the mid-1974 production run or is a non-U.S. (export/home-market) specification vehicle, verify fitment with our team before ordering, as crossmember mount configurations may differ. This kit is not confirmed for MGB-GT, early-production 1974 or pre-1974 MGBs, or non-U.S.-spec cars based on available data.

Frequently Asked Questions

Q: Does this kit fit my 1974 MGB?
A: Prothane designates this kit for 74½–80 U.S. models, meaning it is intended for MGBs built from mid-production-year 1974 onward. Early 1974 cars (built before the mid-year changeover) may not share the same crossmember mount configuration. If your car is an early-1974 or pre-1974 build, please contact our fitment team to confirm before ordering.

Q: Does this kit include all the bushings needed to replace the front crossmember mounts?
A: Yes. The kit contains 6 standard front cross member mount bushings (Prothane #69048) and 2 flat front cross member mount bushings (Prothane #69047) — 8 pieces total — designed to replace all mounting positions on the front crossmember for U.S.-spec MGB models.

Q: Is this kit available in black instead of red?
A: Yes. Prothane produces the 26-49021 kit in both red and black. The listing here is for the red version. If you prefer black to match a stealthy build, contact us and we can point you to the correct option.

Q: What is the warranty on these Prothane crossmember mounts?
A: Prothane covers this kit with a lifetime warranty, which is standard across their polyurethane bushing product line.
