Chassis
XB2’26 features two all-new 2.5mm chassis plates with each one optimized for different track conditions.
XB2C with a mid-length 2.5mm chassis provides the stability needed in higher traction conditions to maximize cornering speeds & to reduce lap times.
XB2D with short 2.5mm chassis maximizes rear traction on lower traction dirt tracks, improving forward acceleration & stability to produce consistent and fast results on even the most irregular surfaces.
Suspension Holders
The improved suspension holder design maximizes durability. Each respective kit features optimized geometry out of the box, ready to hit the track.
The XB2C comes with a 1-degree D-block while the XB2D includes the 3-degree D-block. Thus, the Carpet kit features less toe-in, to free up the rear on high grip tracks. The Dirt kit has more toe-in, to generate more rear traction on a loose surface. The new blocks also allow for a wider track width range adjustment for both kit versions.
Rear Roll Center Holder
New aluminum Rear Roll Center Holder is included in each kit. Its centering milled area for the anti-roll bar collar eliminates play and improves the precision of the anti-roll bar movement.
The new holder also adds an extra middle pivot ball mounting position for additional roll center tuning.
The aluminum holder increases strength & reliability over the previous composite part.
Shock Towers
The rear 6 dot shock tower in the XB2C improves stability and prevents the rear suspension from collapsing during high speed cornering.
Big Bore Shocks
The shock absorbers feature a new 1mm shorter shock cap. The shorter shock cap gives greater up travel during compression of the suspension that is needed to maximize suspension performance in certain conditions and setups.
Shock Adjustments
The XB2C features a -6mm lower shock spring collar to reach lower ride height settings needed on smooth high traction surfaces.
Heavy Duty Titanium Turnbuckles
The XB2 now features ultra-lightweight & strong titanium turnbuckles all made in-house in Europe. The titanium turnbuckles enhance performance in all conditions.
The turnbuckles are very durable thanks to their heavy-duty design and the premium titanium materials.
Titanium Shock Mounts
Ultra-light & strong titanium rear shock mounts are now included as standard in the kit to reduce the weight.
Shocks Springs
4 dot front & rear springs are now included in the XB2C to improve out of the box performance on most carpet tracks. The stiffer spring combination works together with the new shock geometry to provide more consistent handling on carpet and other very high traction conditions.
Wings
To further improve consistency on lower grip dirt tracks, a all-new wider rear wing is included in the XB2D kit. The wider rear wing provides more overall down force, increases traction and enhances rear stability.
Wheel Hubs
The XB2C comes with wider offset wheel hubs - rear 5 slot & front 2 slot, for a more consistent handling on all carpet conditions.
Gear Differential
Lighter diff outdrives reduce rotational mass, improving acceleration, braking, and drivetrain efficiency. The gear differential is suggested for medium to high traction conditions as it increases on-power steering and is beneficial on all carpet tracks.
Ball Differential
The XB2D ball differential offers great performance & durability. Now HUDY Super Diff Grease is included in the XB2D for the most consistent smooth & longest-lasting ball differential assembly.
