Technical summary for the X4F front shock holder

The XRAY 301977 front shock holder is an aluminium component designed to modify shock angle and add +1mm of mount height on the X4F front end, increasing available suspension travel for sharper input absorption.

It features three flex-adjustable mounting positions and accepts thin shims for fine-tuning shock angle and initial compliance, enabling quick tuning trials without full geometry swaps.

Manufactured from Swiss 7075 T6 aluminium, the pair is supplied for both sides of the X4F front assembly and built to handle repeated setup adjustments and track use.

Specifications

  • Item: X4F front aluminium shock holder
  • Material: Swiss 7075 T6 aluminium
  • Model Number: 301977
  • Compatibility: X4F front end
  • Quantity: 2 pcs
  • Adjustable positions: 3 flex positions, shim-adjustable for finer angle increments

Compatibility notes

Intended for X4F front end configurations where a fixed front shock holder is used. Appropriate for touring car and competition-style platforms that accept X4F front assemblies.

Select this holder when you want incremental front shock angle changes and a small travel increase while maintaining reversible mounting adjustments.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does changing the shock angle affect roll behavior?

Altering shock angle shifts how load is taken during roll and can modify the roll center slightly. Using the XRAY 301977 positions and shims helps you tune initial compliance and transient roll response.

Should I adjust shocks after fitting this holder?

Yes. After fitting and selecting shim settings, re-check spring preloads and damping since the altered angle and +1mm height change effective travel and initial shock action.

Can this change help understeer or oversteer?

Depending on setup, increasing front travel and changing angle can soften initial bite or improve compliance over bumps, which may reduce snap oversteer or affect turn-in feel; test changes incrementally.

Do shims give meaningful tuning resolution?

Yes. Thin shims allow small, repeatable angle steps that are useful for refining transient responses and roll onset without replacing larger suspension parts.
