Penske Shocks Shock Absorber

Penske Racing Shocks: Where Championship Damper Technology Meets Custom Craftsmanship

Few names carry as much weight in the world of suspension as Penske Racing Shocks. What began in 1988 as an in-house solution for the Penske Indy Car team has evolved into one of motorsport's most trusted shock absorber manufacturers — a brand whose products have been validated at the highest levels of competition, from the Indianapolis 500 to Formula 1 to the Daytona 500. But what truly sets Penske apart in the shock absorber category is not just its racing pedigree — it's the way every single unit is built.

Hand-Built, Billet-Machined Precision

Unlike mass-market shock absorbers stamped out on an assembly line, every Penske Racing Shock is billet machined and hand-built. Every single shock is billet machined and hand-built — there are no assembly lines, no stamped-out pieces, no off-shore manufacturing — and that personalized attention provides the finest reliability, consistency, and performance. This philosophy means that when you purchase a Penske shock absorber, you are not buying a generic off-the-shelf component. By working with top teams in professional motorsport, PRS continuously learns and develops new technologies that ultimately trickle down their entire product line.

A Model for Every Application

Penske's shock absorber lineup covers an impressive range of racing and performance disciplines, and their numbering system reflects distinct engineering goals for each platform:

• 7300 Series: The 7300 Series damper is the damper of choice in all levels of professional stock car racing — a simple, high-performance shock absorber that can be internally configured easily for any track and tuned externally with a single shaft adjuster.
• 7500 Series: The most versatile shock absorber available, the 7500 Series is offered in a variety of styles and adjustability options, and can be customized to meet any driving style or condition from the track to the street. The double-adjustable coilover version provides separate compression and rebound adjustments without an external reservoir.
• 8300 Series: The 8300 series double-adjustable coilover shock provides separate compression and rebound adjustments with the use of a remote or piggyback external reservoir, with a wide adjustment range making it easily adaptable to varying track conditions.
• 8760 / 8770 Series: The 8760 is among the most universal Penske shocks available, used in a wide variety of professional racing applications, and in its standard configuration is a triple-adjustable coilover damper. The 8770 takes this further with full 4-way adjustability — by offering high and low-speed compression and rebound, the 8770 offers the most versatility with external adjustment, which reduces the need for revalves.
• 7000 Series (Drag Racing): From the 7000 series small bore shocks for lighter applications to heavy-duty systems for Pro Mod and Top Fuel, these are engineered to handle the extreme forces of straight-line acceleration.
• 7700 Thru-Rod: The 7700 Thru-Rod shock is the latest development in short track shock technology — the thru-rod design eliminates the gas pressure feel entirely, so the need for a separate head valve or nitrogen chamber is no longer needed, which drastically reduces running friction and improves consistency.

Adjustability That Keeps Up With You

Models include adjustability levels ranging from non-adjustable up to 4-way adjustable, and can be offered in-line, remote, or piggyback configurations — all utilizing standard Penske internals so you can always use the latest technologies and stay current without purchasing entirely new shocks. This internal standardization is a meaningful advantage: as Penske engineers refine their valving and piston technology, existing owners can upgrade components rather than replace entire units.

Custom-Built for Your Specific Needs

All applications are custom-built to your specific needs, taking into consideration driving style, spring rate, vehicle weight, and type of tracks — ensuring you get a custom shock specific to your application. Penske also provides comprehensive dyno testing services, custom shock rebuilds and re-valving, personalized suspension setup consulting, and ongoing technical support, backed by over 100 years of combined motorsports expertise. Whether you are a professional racing team or a grassroots competitor, Penske offers the same technology and technical support to grassroots racers that it extends to the world's top-tier teams.
