PERRIN Transmission Crossmember Bushings – 2008–2025 Subaru WRX & STI / 2008–2013 Forester / 2013–2023 Crosstrek | Drivetrain Rigidity Upgrade

The PERRIN Transmission Crossmember Bushings are a direct replacement for the factory rubber transmission crossmember bushings on the 2008–2025 Subaru WRX and STI, 2008–2013 Forester, and 2013–2023 Crosstrek — engineered to reduce drivetrain slop, improve shifter feel, and tighten the transmission's mounting rigidity compared to the soft, compliance-oriented factory rubber bushings. The transmission crossmember bushings locate the transmission crossmember to the chassis — and the factory rubber bushings are intentionally soft to isolate NVH (noise, vibration, and harshness) from the drivetrain into the cabin. While effective for NVH isolation, this softness allows the transmission to move under load — contributing to vague shifter feel, drivetrain slop, and inconsistent power delivery. PERRIN's replacement bushings use a firmer material that reduces this movement, delivering a more direct, more precise drivetrain feel without the excessive NVH that fully solid mounts introduce. A straightforward, high-value drivetrain upgrade for any WRX, STI, Forester, or Crosstrek build.

Key Features:

• Firmer bushing material — PERRIN's replacement bushings use a firmer compound than the factory rubber — reducing transmission movement under load for improved shifter feel and drivetrain rigidity
• Reduces drivetrain slop — less transmission movement under acceleration, deceleration, and gear changes — more direct, more precise drivetrain feel
• Improved shifter feel — reduced transmission movement translates directly to a more precise, more mechanical shifter feel — particularly noticeable during aggressive gear changes and performance driving
• Direct bolt-in replacement — engineered as a direct replacement for the factory transmission crossmember bushings — no modification required
• Wide platform compatibility — fits 2008–2025 Subaru WRX and STI, 2008–2013 Forester, and 2013–2023 Crosstrek — a single part number covering a wide range of Subaru platforms sharing the same crossmember bushing specification
• PERRIN Performance quality — manufactured by PERRIN Performance, a respected US Subaru performance brand with a strong following in the WRX and STI community

Performance Benefits:

• Reduced Drivetrain Slop: The factory transmission crossmember bushings are engineered for NVH isolation — their softness allows the transmission to move slightly under load, which absorbs drivetrain vibration but also introduces slop into the drivetrain's response to throttle and gear changes. Under hard acceleration, the transmission can rock slightly in its mounts, causing a momentary delay in power delivery and a vague, imprecise feel at the shifter. PERRIN's firmer bushings reduce this movement — tightening the drivetrain's response and delivering a more immediate, more direct feel under load.
• Improved Shifter Precision: Transmission movement under load directly affects shifter feel — when the transmission moves in its mounts, the shifter moves with it, contributing to a vague, rubbery feel during gear changes. Firmer crossmember bushings reduce this movement, resulting in a more precise, more mechanical shifter feel that is particularly noticeable during aggressive gear changes and performance driving. For WRX and STI owners who value a direct, precise shifter feel, the crossmember bushing upgrade is one of the most cost-effective drivetrain improvements available.
• More Consistent Power Delivery: Reduced transmission movement under acceleration contributes to more consistent, more immediate power delivery — the drivetrain responds more directly to throttle inputs without the momentary compliance that soft factory bushings introduce. For track and performance driving where precise throttle response is important, this improvement is meaningful.
• Balanced NVH Trade-off: PERRIN's bushing compound is selected to reduce transmission movement without introducing the excessive NVH that fully solid transmission mounts generate. The result is a meaningful improvement in drivetrain feel and shifter precision with an acceptable increase in NVH — correct for performance street and track use where some additional NVH is an acceptable trade-off for improved drivetrain response.

What’s Included:

• PERRIN transmission crossmember bushing set — 2008–2025 Subaru WRX & STI / 2008–2013 Forester / 2013–2023 Crosstrek (PERPSP-DRV-141)

Installation Notes:

• Professional installation recommended — transmission crossmember bushing replacement requires supporting the transmission, removing the crossmember, pressing out the old bushings, and pressing in the new bushings before reinstalling the crossmember
• Support the transmission with a transmission jack or suitable support before removing the crossmember — the transmission must be supported throughout the bushing replacement procedure
• Press out the old factory bushings using a hydraulic press or suitable bushing press tool — do not attempt to drive out bushings with a hammer, which can damage the crossmember
• Lubricate the new bushings with a suitable rubber-compatible lubricant before pressing in — this eases installation and prevents bushing damage during pressing
• Torque the crossmember mounting hardware to the factory specification after installation
• Expect a noticeable increase in drivetrain NVH (vibration and noise transmitted into the cabin) compared to the factory rubber bushings — this is normal and expected with firmer bushing material

Why PERRIN Performance?

PERRIN Performance is a US Subaru performance brand with a strong following in the WRX and STI community — known for their intercoolers, intakes, exhausts, suspension components, and drivetrain accessories for Subaru performance platforms. PERRIN's transmission crossmember bushings are a well-regarded, cost-effective drivetrain upgrade for WRX and STI owners who want to improve shifter feel and reduce drivetrain slop without the excessive NVH of fully solid transmission mounts. For Subaru owners who want a quality bushing upgrade from a brand that understands the platform, PERRIN is the correct choice.

Perfect For:

• 2008–2025 Subaru WRX and STI owners seeking improved shifter feel, reduced drivetrain slop, and more direct drivetrain response from a straightforward, cost-effective bushing upgrade
• WRX and STI track day and performance street builds where a more precise, more mechanical drivetrain feel is a priority
• Forester and Crosstrek owners seeking the same drivetrain rigidity improvement on their specific platform
• Owners building a comprehensive Subaru drivetrain upgrade — pairing crossmember bushings with transmission mount bushings, pitch stop mounts, and other PERRIN drivetrain components for a complete drivetrain rigidity improvement

Pro Tip: Pair the PERRIN transmission crossmember bushings with PERRIN's transmission mount bushings and pitch stop mount for a comprehensive drivetrain rigidity upgrade — each component addresses a different point of transmission movement, and the combined effect of all three upgrades is significantly greater than any single component alone.

Note: Expect increased drivetrain NVH compared to factory rubber bushings — this is normal with firmer bushing material. Verify fitment for your specific Subaru model year before ordering. Professional installation recommended.
