Increase the off-road capabilities while improving the comfort and handling of your truck

The 2.5  PIGGYBACK shocks provide the optimal combination of:

• Firm and stable handling for driving on desert and fire roads (sports car feeling);
• Plush compliance while off-road driving over washboard;
• Strong ramping effect for extra bottom-out protection over large dips and washes;
• Maximum articulation and traction for rock climbing.
