The B358 R-COMP shock is physically similar to the B358 but has modified valving to handle higher power applications.
This shock is sufficient to these levels:
-Auto / Turbo up to 1500rwhp
-Auto / Blower up to 1300rwhp
-Auto / Nitrous up to 1300rwhp
-Manual Cars up to 1100rwhp
For applications that have more than 1000rwhp we highly recommend using the KT358U shock.
NOTE: For optimal shock performance we highly recommend aftermarket upper shock mounts
